As I sat there, I ended up reflecting back on 2025. I found myself gravitating to these three questions:

• What went well this year?
• What did I learn?
• What should I focus on next year?

If you’re a leader, I’m guessing you rarely get this kind of thinking time during your workday. I know I don’t. Our calendars are packed with calls, team meetings, and those “quick questions” that turn into two-hour troubleshooting sessions.

But here’s what I’ve learned: the quality of your strategic decisions is directly tied to the quality of your thinking time.

And thinking time doesn’t happen by accident. You have to protect it.

What Went Well This Year?

When I asked myself this question, I didn’t think about our biggest projects or flashiest achievements. I didn’t think about when we migrated almost 2,000 databases as part of an upgrade project. Or the performance tuning we did that resulted in a $36,000 reduction in annual Azure spend for a client.

Instead, I thought about the relationships we strengthened. The trust we built with clients. The problems we solved before they became crises.

For you, this might look like:

• The audit that went smoothly because your security documentation was solid
• The successful disaster recovery test that was possible because you kept refining the process
• The team member you mentored who’s now ready for more responsibility
• The support resources you provided your team through a trusted partner

These aren’t always the things that make it into board reports. But they’re the foundation that everything else is built on.

What Did I Learn?

This year reminded me of something Eisenhower once said: “Plans are worthless, but planning is everything.”

The need for planning cannot be overstated. It’s critical. Even if the plan doesn’t always work out the way you intended.

The plan itself wasn’t the point. The thinking I did while creating the plan was the point.

Because I’d thought through our capacity, our ideal client profile, and our service delivery model, I could adjust quickly when reality didn’t match my spreadsheet. I knew which opportunities were a good fit for us and which ones to let go. Because we’ve intentionally built a small but incredibly talented team that genuinely wants to see our clients succeed, we were able to identify and create ways to help them.

I watched the same dynamic play out with clients. The institutions that had documented their SQL Server environments, tested their disaster recovery plans, and mapped their compliance requirements adapted quickly when needed. They were positioned for success even when the unexpected happened.

Planning isn’t about predicting the future. It’s about building the muscle memory to respond when the future surprises you.

What did you learn this year about planning and adapting? Maybe it was:

• That your three-year technology roadmap needs quarterly reviews, not just annual ones
• That the disaster recovery plan sitting in a SharePoint folder isn’t the same as a tested DR plan
• That “we’ll address that next quarter” eventually becomes “why didn’t we address this sooner?”
• That having an expert on call beats having a plan to find an expert when something breaks

These lessons matter. Write them down. They’re not just hindsight—they’re your blueprint for better decisions ahead.

What Should I Focus On Next Year?

For me, the answer was clear: I need to help more financial institutions and healthcare organizations understand that they have options. Most CIOs think they have two choices for database management: hire a full-time DBA (expensive and hard to find) or make do with whoever can “figure it out” (risky and unsustainable).

There’s a third option: fractional DBA services that give you expert oversight without the full-time price tag.

For you, your focus might be different. Maybe it’s:

• Finally getting your SQL Server environment documented and audit-ready
• Building a disaster recovery plan that you’ve actually tested
• Move a little further along the SQL Server Maturity Curve
• Finding a partner who understands banking compliance, not just databases

Whatever it is, the key is to actually choose something. Not everything. Something. And move toward it. Make progress.

The Power of Quiet Reflection

Here’s the thing about those early Saturday morning moments: they’re rare. And precious.

During the week, we’re in execution mode. We’re responding, reacting, solving, and fixing. That’s necessary work. But it’s not strategic work.

Strategic work requires space. It requires stepping back from the urgent to focus on the important.

So, here’s my challenge to you as we wind down 2025 and usher in the new year:

Block Off Time Just to Think, Then Protect It

Maybe it’s Saturday mornings before your family wakes up. Maybe it’s a long walk at lunch. Maybe it’s 90 minutes with your calendar blocked and your office door closed.

Whatever it is, protect it. The decisions you make during that quiet time about where to focus, what risks to address, and which partnerships to invest in will help shape your entire year.

Your Turn

As you think about the year ahead, I’d encourage you to ask yourself those three questions:

1. What went well this year? Celebrate it. Learn from it.
2. What did I learn? Write it down. It’s wisdom you paid for.
3. What should I focus on next year? Pick one or two things. Not everything.

And if one of those focus areas is “finally get our SQL Server environment to a place where I’m confident, not just hopeful,” let’s talk. That’s exactly what we help institutions do.

If you’re a CIO wondering whether your SQL Server environment is as healthy and secure as it should be, I’d be happy to have a conversation. No sales pitch. Just two people talking candidly about database management. Schedule a time here.

Whether you’re planning an upgrade from an aging SQL Server instance or simply staying informed about where the platform is headed, here’s what you need to know about SQL Server 2025 and how it might affect your institution.

What’s New in SQL Server 2025?

Major Changes to SQL Server Editions

Let’s start with the news that will matter most to budget-conscious institutions: SQL Server 2025 Standard Edition now supports up to 32 CPU cores and 256 GB of RAM. This is a substantial increase from previous limits and could significantly affect your licensing decisions.

For many community banks, this expanded capacity means Standard Edition can now handle workloads that previously required Enterprise Edition licensing. Given the price difference between editions, this change alone could translate into meaningful cost savings on your next upgrade or new deployment.

Express Edition also received an upgrade, with the maximum database size increasing to 50 GB. While Express isn’t typically used for core banking systems, this expanded limit makes it more viable for development environments, smaller branch applications, or testing scenarios.

Microsoft also introduced a new Standard Developer Edition that offers full feature parity with Standard Edition. This allows your development and testing environments to mirror production limitations more accurately, reducing surprises when you deploy.

Performance Improvements That Require No Code Changes

SQL Server 2025 includes over 50 enhancements to the database engine, with several performance improvements that take effect automatically—no application changes required.

The most significant is optimized locking, which uses Transaction ID locking and lock-after-qualification features to improve concurrency. In practical terms, this means reduced row and page locks during data modifications, which translates to better performance for high-transaction environments like core banking systems.

For institutions that have struggled with unpredictable tempdb growth, SQL Server 2025 introduces tempdb resource governor options that let you control how much tempdb space individual users or processes can consume. This provides better resource management and helps prevent runaway queries from affecting other workloads.

The release also includes a new ZSTD backup compression algorithm, which is particularly valuable for large database backups. Faster, more efficient backups mean shorter maintenance windows and reduced storage costs—both welcome improvements for institutions managing growing data volumes.

Security Enhancements for Regulated Industries

Security remains a top priority for SQL Server, and the 2025 release continues that focus with several enhancements relevant to financial institutions.

SQL Server 2025 integrates with Microsoft Entra for identity and access management, supporting multi-factor authentication, role-based access control, and condition-based policies. For institutions already using Microsoft’s identity services, this provides a more unified security posture across your environment.

The release also introduces enhanced password protection using a password-based key derivation function that follows NIST SP 800-63b compliance guidelines. Additionally, security cache improvements reduce the performance impact of permission changes in high-concurrency environments—a common scenario in banking applications with thousands of active connections.

For institutions running SQL Server on Linux, version 2025 adds TLS 1.3 support, custom password policies, and signed container images. Platform support also expands to include RHEL 10 and Ubuntu 24.04.

Built-In AI Capabilities

Microsoft is positioning SQL Server 2025 as the “AI-ready enterprise database,” and this release includes native support for AI workloads directly within the database engine.

New features include a native vector data type, built-in vector search capabilities, and integrated model definitions that can be defined directly within T-SQL. The new sp_invoke_external_rest_endpoint stored procedure allows you to call AI services like Azure OpenAI or ChatGPT directly from your database.

For financial institutions, these capabilities open possibilities for fraud detection, customer service automation, document processing, and other AI-driven applications without requiring separate infrastructure for vector databases or AI model hosting. However, as with any new technology in regulated environments, careful evaluation and appropriate governance will be essential before production deployment.

Developer Productivity Enhancements

SQL Server 2025 brings several features that streamline development and reduce code complexity. Native JSON support now handles documents up to 2 GB per row with dedicated JSON indexes for improved query performance. Regular expression support is now built directly into T-SQL, eliminating the need for third-party tools or workarounds.

Change Event Streaming allows real-time, event-driven applications by streaming changes directly from the transaction log to Azure Event Hubs or Kafka. Native REST API support through system stored procedures enables richer integrations with external services.

These enhancements make SQL Server more capable for modern application architectures while maintaining the reliability and security that regulated industries require.

Key Takeaways and Institutional Impact

SQL Server 2025 delivers meaningful gains for community banks and financial institutions, combining expanded Standard Edition limits, stronger security aligned with compliance expectations, and automatic performance improvements that benefit high-transaction environments. These enhancements can reduce licensing costs, improve reliability, and support more modern workloads without major application changes.

Planning Your Upgrade Path

SQL Server 2025 supports in-place upgrades from SQL Server 2014 or later, and migration methods work all the way back to SQL Server 2008. With SQL Server 2016 reaching the end of its extended support in July of 2026, now is a good time to evaluate your upgrade timeline.

Before upgrading production systems, thoroughly test your applications against the new version. While SQL Server releases rarely include major breaking changes, version 2025 does adopt TDS 8.0 with TLS 1.3 support, which can affect linked servers and replication configurations. Identify these dependencies early to avoid surprises. You’ll also want to verify support from vendor-provided applications.

A reactive approach may get you through the day, but it doesn’t build long-term stability, security, or confidence.

What is the SQL Server Maturity Curve?

Over the years, we’ve found that every SQL Server environment naturally falls somewhere along a maturity curve. Understanding where your SQL Server environment is today and where you want it to be helps you move from firefighting to foresight. SQL Server maturity can be best understood in four stages: reactive, managed, optimized, and strategic.

Let’s look at each stage.

1. Reactive: Firefighting

At the lowest level of maturity, we have what we call the reactive stage. This is where SQL Server environments are managed more in a ‘break/fix’ mode. Something goes wrong—an outage, a performance issue, maybe even a regulatory problem—and the team jumps in to fix it. Since the problem usually catches them by surprise, they then have to spend time figuring out how to address the issue before they can start to fix it.

Banks in this stage tend to rely heavily on manual processes and have very little automation in place. There might be some monitoring, but it’s often not tailored to SQL Server and effectively too generic (maybe something like SolarWinds Orion). So, leaders don’t have a clear picture of what’s healthy, what’s risky, or what’s about to break.

A second indicator for this stage is an environment where no one person is truly accountable for SQL Server. It’s a shared responsibility, which really means no one’s watching it closely. It’s just one of many systems all lumped in together. In these environments, small problems slip through the cracks until they turn into something big.

A third indication is the assumption that the vendor or core provider is handling all necessary SQL Server maintenance. In reality, they’re not watching it nearly as closely as the bank thinks they are.

From a business standpoint, this leads to high operational costs, more regulatory findings, and frustrated employees and customers when things go down.

Most of the SQL-related budget at this stage goes toward putting out fires instead of preventing them. Unfortunately, this is still where a lot of community banks find themselves today—operating in a reactive state, vulnerable to risk, and always one incident away from disruption.

2. Managed: Gaining Control

The next stage up in the curve is the managed stage. In this stage banks start putting some structure in place.

Backups are running consistently. And I know what you might be thinking: ‘Of course they are.’ But you’d be surprised how often we hear that, only to find something very different once we dig in during an SQL Health Check.

Monitoring is usually turned on so the team gets alerted before things get out of hand, and patching is scheduled instead of done haphazardly.

You’ve probably heard the phrase people, processes, and technology. At this stage, banks are making solid progress on two of those: processes and technology. And there’s usually someone in IT who’s been given responsibility for SQL Server, though it’s often just one of the many things they take care of.

But the results are noticeable. Incidents are happening less often, performance is steadier, and compliance is easier to manage. There’s even some separation of duties starting to take shape.

Here, most of the SQL-related budget is still going toward maintenance, but now, instead of pure firefighting, a little bit of that time and money is shifting toward planning and improvement.

So the managed stage is a big step forward. Things are more stable, there are fewer surprises, and the environment is definitely safer. But it’s still not efficient—and it’s not yet resilient. That’s usually when the question shifts from ‘Are we stable?’ to ‘How can we do this better?’

3. Optimized: Running Proactively

Third is the optimized stage; things start to look and feel different. We’re no longer spending most of our time just keeping the lights on; the focus shifts from maintenance to efficiency.

Routine tasks like backups and testing the backups, patching, and monitoring are automated and standardized across the SQL Server environment. The team’s not reinventing the wheel on every server anymore. Builds are standardized and perhaps even automated.

Performance is managed proactively—indexes, queries, and resource usage are being reviewed on a regular basis. The bank finally has real visibility into capacity, performance trends, and risks over time.

And all that optimization pays off literally.

At this stage, banks start saving real money. They’re doing proactive performance tuning, right-sizing their environments, and consolidating where it makes sense. That means fewer servers, lower licensing costs, and less wasted hardware.

We worked with one client who was able to save about $2,000 a month—$24,000 a year—on just one of their Azure SQL Servers, simply by tuning and optimizing the setup.

And another bank we work with was able to cut their SQL footprint in half through consolidation and decommissioning efforts. That saves on licensing costs, management costs, etc.

But it’s not just about cost savings. This is also where security gets stronger. Misconfigurations get closed off, permissions are tightened, and the environment starts aligning with best practices like the CIS benchmarks and the principle of least privilege.

The payoff is easy to see. Customers experience faster, more reliable systems. Inside the bank, IT teams aren’t scrambling to fix the latest outage—they’re staying ahead of it. They identify and resolve issues before they impact operations or audits. SQL Server becomes a reliable foundation that actively supports business goals.

4. Strategic: Turning Data into Advantage

In the final stage, the strategic stage, SQL Server isn’t just stable or secure; it’s resilient by design.

High availability is built in. Disaster recovery plans aren’t just written; they’re tested and refined. Security is strong and consistent across the environment, and compliance isn’t something the team scrambles to prove once a year; it’s woven into daily operation.

Auditing and monitoring tools are in place. There’s clear separation of duties. And reporting infrastructure is mature enough to shift workloads where they make the most sense.

But what really sets this stage apart is how SQL Server starts to enable the business.

At this point, it’s not just about avoiding risk; it’s about driving strategy.

Data becomes a competitive advantage. Executives have access to real-time insights through analytics and reporting. They can spot trends, understand customer behavior, and make better decisions—faster.

And IT? It’s no longer seen as a cost center. It’s a business enabler—helping drive efficiency, innovation, and growth.

Moving Up the Curve

Wherever your institution is today, the goal isn’t perfection overnight. It’s steady progress. Moving even one stage up the maturity curve can dramatically reduce risk, improve audit readiness, and free up your team to focus on higher-value initiatives.

The key is to be intentional, to assess, document, and continually refine your SQL Server management practices.

Because in business, in banking, and in healthcare, SQL Server maturity isn’t just an IT milestone; it’s a business advantage.

What are the benefits of enabling Query Store? While there are many technical reasons, here are my top four broad advantages to consider.

1. Free SQL Server monitoring

Your business has already paid for Query Store in the SQL Server licensing. With SQL Server 2016 and later, it is accessible at the database level. This means that for smaller shops that may not have a large enterprise environment, you don’t have to spend large sums of money to get observability from 3rd party software. Query Store’s native capture mechanisms can provide significant insight into your SQL Server’s performance, all without costing you any more money!

2. Capture foundational SQL Server performance indicators

Query Store collects the data already present in your SQL Server, displaying it in easy-to-understand graphs and reports. With Query Store, values for CPU, memory, duration, and more can be viewed based on MAX/AVG/STD Deviation metrics per query. This provides valuable insights into core metrics that shape the performance of your applications. Furthermore, this data allows your company to see not only how specific queries behaved when there was a performance problem but also to trend those queries over time to see shifts in performance.

SQL Server wait statistics are also captured and displayed in Query Store. When a query needs a resource, like CPU, or data read from disk, then a wait type is assigned to the query. These various waits affect query performance in a multitude of ways, and Query Store surfaces those performance-impacting waits for you. For example, the Query Wait Statistics report may show large bar graphs for BUFFER IO and CPU. Queries appearing in both graphs may be suffering from large table scans because of missing indexes.

Additionally, Query Store captures the query plans associated with queries. Think of query plans as the blueprint for how the query will be executed. These plans contain data about the decisions SQL Server is making about your data and how to process it. Some decisions revealed in the query plan can pinpoint performance issues. For example, query plans that regularly contain table scan operators may indicate missing indexes that force SQL Server to scan millions of rows when it only needs to retrieve a few thousand rows.

3. Talk to your vendors with data in hand

COTS vendors need to see hard data when approached with a performance problem. Query Store can provide that data. Without it, you can report a problem, but the software vendor is unlikely to consider making changes.

If you engage a DBA as a Service company, having performance data in hand will go a long way toward building a good relationship with that vendor. They will see your preparedness and be drawn to that. Also, it will allow them to solve your problem faster, and isn’t that what you really want anyway?

4. Allow your applications to take advantage of new performance features

Newer versions of SQL Server have a collection of features known as Intelligent Query Processing (IQP). Features such as memory grant feedback, degree of parallelism feedback, and more are tied into IQP. These features depend on Query Store. Without Query Store running and without using the appropriate database compatibility level, your applications are missing out on performance-enhancing features that make queries execute faster, use fewer resources, or do both at the same time.

Still, even if your technical team sees the need, it can be tough to make the business case to your CFO. Since managed services would be an ongoing investment, how do you best convey their value?

Here’s how to frame that conversation to maximize your odds of getting buy-in from financial leadership.

1. Start With the Business Impact, Not the Tech

CFOs think in terms of financial risk, cost control, and business outcomes. So instead of leading with patching, query tuning, or Always On configuration, focus on:

• Avoiding costly downtime
• Reducing licensing waste
• Freeing up internal staff for higher-value work
• Protecting customer data and ensuring compliance

Example: “We had 4 hours of unplanned SQL Server downtime last year, which impacted billing, customer support, and payroll processing. Managed services would help us avoid that kind of disruption.”

2. Quantify the Cost of Doing Nothing

IT leaders often struggle to justify costs because the risk feels abstract. Make it real by putting numbers to:

• Cost of downtime: How much are lost productivity and missed revenue costing you during each outage?
• Opportunity cost: What projects are delayed because your team is busy firefighting?
• Audit and compliance penalties: Noncompliance with data protection rules (e.g., SOX, HIPAA) can get expensive fast.

If you’re not sure where to start, consider a health check or audit to quantify current gaps and risks. These numbers can make a compelling case.

3. Emphasize Cost Efficiency Over Hiring

Hiring a full-time SQL Server DBA can cost over $120,000 per year between salary, benefits, and overhead. Even after this substantial investment, you’d still have only one person managing all of your business’s needs.

With managed services, you get a team of SQL Server experts for a fraction of the cost of building that capability in-house. That includes:

• 24/7 monitoring and alert response
• Proactive maintenance
• Performance tuning
• Disaster recovery support
• License optimization

It’s not just cheaper—it’s more scalable and more reliable.

4. Show That It’s More Than Emergency Help

Many CFOs assume managed services are only about putting out fires. Make sure they understand that SQL Server managed services also work proactively. Here are a few examples of ways to highlight the potential benefits to your business:

• Preventive maintenance reduces long-term costs.
• Regular reviews help improve system performance.
• Guidance on upgrades, cloud strategy, and license optimization saves money over time.

5. Tie It to Business Continuity

When SQL Server goes down, so does the business, and CFOs understand the financial impact of disruption. Managed services ensure that:

• Your backups are actually restorable.
• Failover mechanisms are in place and tested.
• RPOs and RTOs align with business expectations.

That kind of readiness can make or break a company in a crisis.

6. Provide a Clear ROI Narrative

It can help to build a before-and-after picture:

• Before: unplanned downtime, poor performance, reactive fixes
• After: stability, predictability, reduced risk

Highlight cost savings from:

• Consolidating underused instances
• Reducing overprovisioned licenses
• Avoiding emergency consulting fees

Then, present it using the CFO’s language: predictable monthly spend, reduced risk exposure, and higher operational efficiency.

7. Offer a Pilot or Assessment

If your CFO is hesitant, suggest a low-risk starting point:

• A fixed-fee health check
• A short-term pilot engagement
• A time-boxed cost optimization review

This allows them to see the value for themselves before committing.

Why Your CFO Might Say Yes

SQL Server managed services aren’t just an IT expense—they’re a strategic investment in uptime, security, and efficiency. When you frame the conversation in terms your CFO cares about—cost, risk, and business continuity—you’ll be much more likely to get buy-in.

It’s a question too many teams avoid until it’s too late. But between rising cybersecurity threats, growing compliance expectations, and increasing reliance on real-time data, a solid SQL Server disaster recovery (DR) plan is no longer optional.

Here’s how to assess your plan’s strength—and where to start if you’re not sure you’d pass the test.

1. Do You Know Your RPO and RTO?

Your Recovery Point Objective (RPO) defines how much data you’re willing to lose. Your Recovery Time Objective (RTO) defines how quickly you need to be back online.

Together, these two metrics set the target for your disaster recovery plan. But we’ve seen organizations that think they have a DR plan—only to realize they’ve never clarified what “acceptable loss” actually means to the business.

Start by working with your business stakeholders to define these values. Then validate whether your current backups, logs, and failover strategies can actually meet them.

2. Are Your Backups Frequent, Verified, and Offsite?

Most SQL Server environments have some backup process in place. But that doesn’t mean the backup strategy is effective.

Ask yourself:

• Are backups scheduled frequently enough to meet your RPO?
• Are you testing your ability to restore from backups regularly?
• Are copies stored securely offsite (or in a different cloud region) in case of catastrophic failure?

In our SQL Health Checks, we’ve seen corrupted backups, failed jobs, and local-only storage that would all fail under real-world disaster conditions. A good DR plan doesn’t just back up data—it proves you can get it back.

3. Have You Tested Your Disaster Recovery Plan Recently?

You can’t consider your disaster recovery plan “ready” if you’ve never run a test failover.

Tabletop exercises are a great start—especially for small teams—but ideally, you should test end-to-end failover and recovery at least once a year. That means

• Simulating a system failure
• Measuring time to recovery
• Evaluating data loss
• Reviewing stakeholder communication plans

Don’t forget to test people, too. Everyone involved should know their role and how to execute it under pressure.

4. Does Your DR Plan Include All Critical Dependencies?

Even if your SQL Server environment comes back online quickly, that won’t matter if key application servers, file shares, or authentication systems are down.

A strong SQL Server disaster recovery plan takes into account all supporting systems:

• Application and web servers
• Reporting tools (like SSRS or Power BI gateways)
• Authentication (like Active Directory or Azure AD)
• Networking and firewall configurations

Your DR plan should address each of these and ensure that your failover environment mirrors production closely enough to support full functionality.

5. Are You Leveraging the Right Technology?

SQL Server offers multiple high-availability and disaster recovery (HADR) features, but they’re not all created equal. The best choice depends on your budget, environment size, and RPO/RTO needs.

Your options include

• Log shipping: Simple and reliable, but with slower failover requiring manual intervention.
• Database mirroring: Deprecated but still in use in some legacy systems.
• Always On Failover Cluster Instances (FCI): Protects against server failure.
• Always On Availability Groups: Great for fast failover and readable secondaries, but more complex to set up and manage.

The right SQL Server consulting partner can help you match your business needs to the most appropriate technology stack—and make sure it’s implemented correctly.

6. Have You Documented and Updated Your Plan?

Even the best disaster recovery setup won’t help you if no one knows how to use it, or it walks out the door in the head of your DBA or sysadmin. A strong DR plan is

• Written and version-controlled
• Stored in a location accessible even during an outage
• Reviewed and updated at least annually
• Understood by all relevant stakeholders

You want more than just a technical diagram—you want a full playbook your team can follow under stress.

Final Thoughts: DR Is a Process, Not a Project

Disaster recovery isn’t a one-time task. As your environment evolves, so should your plan.

6 Reasons for a Side-by-Side SQL Server Upgrade

Here are the key reasons why this approach consistently delivers better outcomes for our clients.

1. Minimize Downtime During SQL Server Upgrades

Downtime is costly—especially for businesses that rely on 24/7 access to data. With a side-by-side upgrade, we build the new SQL Server environment in parallel with your existing one. This allows us to configure, test, and validate everything before the final cutover. When it’s time to go live, we simply migrate the latest data and switch over, often with just a few minutes of downtime. This approach ensures business continuity and avoids the stress of a high-stakes, all-at-once upgrade.

2. Reduce Risk with a Built-In Rollback Plan

In-place upgrades modify your production environment directly. If something goes wrong—whether it’s a compatibility issue, a failed service, or a corrupted database—your options for recovery are limited, most likely to restoring a VM snapshot. Side-by-side upgrades, on the other hand, preserve your original environment until the new one is fully operational. If issues arise, we can pause, troubleshoot, or even revert without impacting your live systems. It’s a safer, more controlled way to upgrade.

3. Test Everything Before You Go Live

SQL Server upgrades can introduce changes in behavior, deprecated features, or performance shifts. You can mitigate that to some extent with the Data Migration Assistant. However, the proof is in the production environment. With a side-by-side setup, we can test stored procedures, jobs, reports, and integrations in a sandboxed environment. This ensures that everything works as expected before we make the switch. It also gives your internal teams and application owners time to validate their workflows, reducing surprises post-upgrade.

4. Start Fresh with a Clean SQL Server Installation

Over time, servers accumulate clutter like old settings and deprecated features in the operating system and in SQL Server. (SQL Server Notification Services anyone?) A side-by-side upgrade gives us the opportunity to start fresh. We work with your team to install a clean operating system and SQL Server instance, apply current best practices, and migrate only what’s needed. This results in a leaner, more secure, and better-performing environment.

5. Migrate Applications Gradually

Not all applications are ready to move at the same time. Some may require vendor coordination, code changes, or additional testing. A side-by-side upgrade allows us to migrate applications incrementally. We can move one app at a time, validate its performance, and ensure it’s stable before moving on to the next. This phased approach reduces risk and makes the transition smoother for everyone involved.

6. Align with Compliance and SOC 2® Requirements

For organizations pursuing SOC 2® certification or operating in regulated industries like healthcare and finance, documentation and auditability are critical. Side-by-side upgrades can offer better change control, clearer audit trails, and more structured testing. We can demonstrate due diligence at every step—something that can be harder to do with an in-place upgrade.

Still Not Sure?

While in-place upgrades may seem faster on the surface, they often come with hidden risks and limitations and can also carry over existing issues. A side-by-side SQL Server upgrade offers more control, better testing, and a safer path forward.

Core banking environments are complex. They handle everything from transaction processing and customer account management to regulatory reporting and data security. Your SQL Server partner must understand not only the technical architecture but also the core banking systems’ operating requirements.

Expect your partner to ask the right questions about your environment, your data dependencies, your peak usage times, and your business continuity and recovery needs. The best SQL Server consultants come equipped with industry experience and a blueprint for helping banks navigate change.

Core banking system providers are experts in their own software, but they’re not always expert SQL Server administrators. That’s where a specialized SQL Server consultant adds value. They ask the right infrastructure questions, including about Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs). These metrics help ensure your SQL environment supports your business continuity and disaster recovery needs. A knowledgeable SQL partner can turn those objectives into strategies like point-in-time recovery, automated failover, and high-availability design.

2. Rigorous Planning and a Clear Project Timeline

A core banking database upgrade isn’t something to approach casually. Your SQL Server partner should help you scope and sequence every phase of the upgrade, including:

• Environment assessments and baseline performance benchmarks
• Compatibility testing with the new infrastructure
• Backup and restore strategies for rollback protection
• Performance settings recommendations
• Cutover planning and go-live support

Look for partners who can produce a detailed project plan and who proactively manage timelines, milestones, and communication. You shouldn’t have to tolerate surprises—and neither should your customers.

3. Zero-Downtime (or Near-Zero) Migration Strategies

Unplanned downtime in core banking systems means customer impact, reputational risk, and possible regulatory scrutiny. SQL Server partners should be able to offer strategies that minimize or eliminate unexpected downtime through:

• High availability (HA) and disaster recovery (DR) design reviews
• Pre-migration dry runs to simulate live scenarios
• Staged cutovers during low-usage periods

Expect your partner to not only explain these strategies but also test and validate them in your environment before launch day.

4. Compliance and Security Oversight

With the FFIEC sunsetting its Cybersecurity Assessment Tool and CIS® Benchmarks™ gaining ground as the new standard, your SQL Server partner must be fluent in financial data security requirements.

They should review your SQL Server configuration for gaps, recommend security hardening, and help you prepare for both internal and external audits. This includes:

• Encrypted backups and secure storage
• Role-based access controls
• Configuration baselines aligned with best practices
• Detailed documentation for compliance reviews

5. Post-Upgrade Monitoring and Support

A good partner doesn’t just help you upgrade. They help you meet your regulator with confidence.

The job isn’t finished when the core system goes live. The first few weeks post-upgrade are critical. Your SQL Server partner should offer extended support to monitor system performance, resolve unexpected issues, and ensure optimal database operation.

Banks should expect:

• Real-time monitoring for performance and error trends
• Rapid-response troubleshooting
• Ongoing patching, maintenance, and tuning
• A smooth transition to in-house teams or ongoing DBA-as-a-Service

This post-upgrade care is what separates good partners from great ones.

What if you could retire two aging SQL Server 2016 failover clustered instances, migrate 1,200+ databases to SQL Server 2022, and slash storage spend by 84%—all in the length of a weekend maintenance window?

In this post, I’ll tell you exactly how we did it for a client using AWS.

We had multiple goals for this migration:

• Move to SQL Server 2022 and Windows Server 2022
• Reduce Amazon AWS storage costs
• Minimize the downtime required for the migration

The environment consisted of two SQL Server 2016 Enterprise failover clustered instances hosting over 1,200 production databases. As you may know, mainstream support for SQL Server 2016 ended on July 13, 2021, with extended support ending on July 14, 2026 (which is approaching quickly). This post explains how we successfully migrated this complex environment with less than 3 hours of planned downtime while simultaneously reducing infrastructure costs by transforming their storage architecture and backup strategy.

Key Results:

• 1,200+ databases migrated with minimal business disruption.
• Infrastructure storage costs reduced by 84% (estimated).
• SQL Server platform modernized from 2016 to 2022.

Client Profile

Industry: Education software

Environment:

• Two SQL Server 2016 Enterprise failover clustered instances in Amazon AWS
• FSx file share volumes for database storage
• FSx file share for backups
• Multi-subnet configuration
• 1,200+ production databases ranging from 1GB to 3TB in size
• 24/7 business operations with minimal tolerance for downtime

The Challenge

Business Drivers:

The client approached us with several business requirements:

Cost Reduction: Their existing FSx storage and backup architecture was consuming an unsustainable portion of their IT budget.

Technology Modernization: SQL Server 2016 was approaching the end of extended support, requiring an upgrade path to maintain vendor support and security compliance.

Minimal Disruption: With 1,200+ production databases supporting critical business functions, any migration solution needed to minimize downtime.

Technical Challenges:

The technical landscape presented several significant obstacles:

FSx Storage Cost and Performance

The client’s reliance on Amazon FSx for Windows File Server provided the necessary shared storage functionality for their SQL Server failover clusters, but at a premium price point. The FSx architecture also introduced additional network latency for I/O operations, affecting database performance.

Complex Multi-Subnet Configuration

The existing environment leveraged a multi-subnet configuration, adding complexity to any potential migration solution.

Database Scale and Diversity

With over 1,200 databases that vary dramatically in size, usage patterns, and business criticality, a one-size-fits-all migration approach would be insufficient.

Backup Architecture Limitations

The existing backup strategy relied on additional FSx storage, increasing the storage costs while creating management overhead.

Strict Downtime Constraints

The business could tolerate a maximum of 8 hours of downtime, with a strong preference for staying under 4 hours to minimize impact on operations.

The Solution

After a comprehensive analysis and planning, we designed a phased approach that would transform the client’s database infrastructure while meeting their strict requirements for minimal disruption.

Solution Architecture

We architected a modern SQL Server environment on AWS with the following components:

1. Platform Upgrade:
   • SQL Server 2022 Enterprise Edition
   • Leveraged latest features and extended support lifecycle
2. Storage Transformation:
   • From FSx file shares to Multi-Attached EBS volumes
   • io2 Block Express volumes for critical data files
   • Optimized configuration for SQL Server workloads
3. Backup Modernization:
   • Implement S3-based backup strategy
     • Direct SQL Server native backup to S3
   • Intelligent lifecycle policies for cost-effective long-term retention
   • Elimination of dedicated backup storage infrastructure
4. High Availability Design:
   • SQL Server 2022 FCI
   • Modern monitoring integration

Implementation Approach

We divided the implementation into distinct phases to manage risk and ensure successful outcomes.

Phase 1: Development Environment Migration

We began with the client’s development environment to validate our approach and identify potential issues. We worked with the client’s internal system admins to complete the EC2 instance and Windows Server Failover Cluster builds. This allowed us to focus mainly on the SQL Server FCI components:

1. Infrastructure Provisioning:
   • Deployed new EC2 instances optimized for SQL Server 2022
   • Configured multi-attached EBS volumes
   • Established networking and security configurations
2. Initial Testing:
   • Validated storage performance
   • Confirmed failover functionality and timing
   • Verified backup and restore operations to S3
3. Migration Dry Run:
   • Executed migration process on a subset of development databases
   • Measured migration times
   • Refined automation scripts based on observations

Phase 2: Production Environment Preparation

With lessons from the development migration incorporated, we prepared for the production migration:

1. Pre-Migration Activities:
   • Comprehensive database inventory and dependency mapping (i.e., agent jobs, applications, etc.)
     • Planning, communication, and task tracking were crucial to the overall success of the migration.
   • Database health checks to identify potential migration blockers
     • Including utilizing Microsoft’s Data Migration Assistant to ensure database compatibility
   • Implementation of enhanced monitoring
2. Automation Development:
   • Custom PowerShell script creation for orchestrating the migration
   • Integration with DBATOOLS for database backup and restore operations
3. Infrastructure Deployment:
   • Production SQL Server 2022 cluster provisioning
   • Multi-attached storage configuration and testing
   • S3 bucket preparation with appropriate security and lifecycle policies
   • Tested access to the current backup location from the new SQL Server 2022 instances (permissions and network access)

Phase 3: Production Migration Execution

The production migration followed our carefully orchestrated plan:

1. Pre-Stage Initial Data:
   • Performed initial data copy without taking systems offline
   • Utilized a combination of native Full, Differential, and Log backups
   • Leveraged the rebuilt PowerShell script to perform the initial full restore and differential restore
   • Restored log backups every 30 minutes
   • Scheduled restores via the SQL Server Agent on the new SQL Server 2022 FCIs
   • Established baseline synchronization to minimize final transfer time.
2. Migration Window Execution:
   • Implemented application maintenance mode at the start of the maintenance window, blocking access
   • Executed the final data synchronization using our custom migration script
     • Tail-log backup was used to capture all transactions and place the database on the SQL Server 2016 instances into “recovering” status
       • This accomplished two important goals:
         • Capture all transactions that have occurred since the last transaction log backup
         • Place the database into a “recovering” state so that new connections were not allowed in the old environment
   • Performed database restores on the new SQL Server 2022 instances using all transaction log backups, including the final tail-log backup
     • Databases were then recovered and placed into a multi-user read-write state
   • Raised the database compatibility level to 160
   • Changed the database owner
   • Validated each database post-migration
   • Initiated post-migration full backups
3. Cutover:
   • Updated connection strings and DNS entries
   • Performed final validation testing
   • Opened systems for production use

The Technology

Multi-Attached Storage Architecture

The shift from FSX to multi-attached EBS volumes represented one of the most significant technical innovations in this project. We configured the volumes with performance characteristics matched to their specific workloads:

• Data volumes: 3,000 IOPS
• Log volumes: 3,000 IOPs
• TempDB volumes: Amazon EC2 instance store volume (local to each EC2 instance)

This approach delivered both performance improvements and significant cost savings compared to the FSx solution.

Custom Migration Automation

The scale of this migration—over 1,200 databases—demanded sophisticated automation. We developed a custom PowerShell script that utilized multiple commandlets from the DBATools module.

DBATools Integration

While our custom script orchestrated the overall migration process, we leveraged the power of DBATools—an open-source PowerShell module for SQL Server management—for many of the core database operations. This combination of custom automation with proven community tools provided the perfect balance of flexibility and reliability.

Key DBATools functions employed included:

• Get-DBABackupHistory to retrieve the latest backup information for each database.
• Restore-DbaDatabase for restoring the initial full, differential, and all t-log backups.

The Results

The migration was completed successfully with impressive metrics:

Cost Reduction

• 84% reduction in monthly storage costs

Business Impact

• Minimal disruption: Total downtime of only 2 hours and 55 minutes, well under the 8-hour target
• Extended support lifecycle: Movement to SQL Server 2022 provides support through 2032
• Performance headroom for growth: New infrastructure accommodates projected 55% database growth

Migration Metrics

• Total databases migrated: 1,235

Key Lessons Learned

Throughout this project, we gained valuable insights that would benefit any organization undertaking a similar database migration:

1. Thorough database inventory is critical
   • Understanding dependencies between databases was crucial
   • Early identification of current database sizes allowed for proper allocation of storage to support the migration.
2. Storage strategy has an outsized impact
   • Moving to multi-attached EBS volumes delivered both cost and performance benefits
   • SQL Server 2022 introduced the ability to backup directly to S3, delivering significant storage savings vs. FSx
3. Automation is non-negotiable at scale
   • Manual migration for 1,200+ databases not possible within time constraints
   • Investment in custom automation paid dividends in reliability and speed
4. Pre-staging reduces risk
   • Copying the bulk of data before the migration window dramatically reduced the final migration time
   • Delta synchronization proved highly efficient using t-log backups
5. Multi-phase approach validates methodology
   • Starting with the development environment allowed refinement of techniques
   • Lessons learned in initial phases improved production migration execution

Conclusion

This post demonstrates how even the most challenging database migrations can be accomplished with minimal downtime when approached with careful planning, appropriate technology choices, and custom automation. By transforming the storage architecture and leveraging modern AWS services, we not only successfully migrated 1,200+ SQL Server databases but also delivered substantial cost savings and performance improvements.

For organizations facing similar challenges with aging SQL Server environments, this project provides a proven blueprint for success—combining the best of cloud infrastructure, modern database platforms, and sophisticated automation techniques.

The client now enjoys a modern, cost-effective SQL Server environment that provides room for growth while reducing ongoing operational costs. Most importantly, they achieved this transformation with minimal disruption to their business operations—proving that with the right approach, large-scale database migrations don’t have to be painful or disruptive.

But a recent experience undermined their confidence in that approach.

Their core banking system SQL Server went down — not for minutes, but for two full days. The outage impacted operations, delayed customer services, and created immediate compliance concerns.

The core banking application provider eventually restored the system. But when I asked what had caused the outage, what was done to resolve it, and how they were ensuring it wouldn’t happen again, the answer was unsettling: “We just don’t know.”

The Hidden Risk of Relying Solely on Application Vendors

That moment of uncertainty is not uncommon. Application vendors are excellent at supporting their software. They should be, after they created it and know it inside and out. But SQL Server performance and resilience require a different level of focus and expertise.

This isn’t a critique of the vendor — it’s a reality check.

When no one is actively managing your SQL Server’s health, backups, indexing strategy, or failover configuration, issues can go unnoticed until they cause real and lasting damage.

SQL Server is the heart of many business applications. It needs more than passive and reactive care — it needs proactive, specialized attention.

Why SQL Server Downtime Is More Than an IT Problem

For regulated institutions like banks and healthcare organizations, database outages aren’t just technical glitches. It’s not like the printer is being finicky again. Problems with SQL Servers present very real business and compliance risks. Downtime erodes customer trust, disrupts internal workflows, and can even trigger audits or fines. Not to mention the security implications of an ignored SQL Server.

What’s more troubling is when an organization doesn’t have answers. No root cause. No remediation plan. No visibility. That’s when leadership starts asking tough questions — and rightly so.

How to Regain Control of Your SQL Server Environment

The good news? It doesn’t have to be this way.

At The SERO Group, we provide SQL Server managed services designed to help highly regulated industries keep their SQL Server healthy, secure, and reliable. We help organizations

• Proactively monitor and optimize SQL Server performance
• Investigate and resolve potential issues before they become disruptive events
• Deliver clear reporting and visibility to IT and business leaders
