When to Upgrade Your SQL Server (And When to Stick With What You Have)

SQL Server is a critical part of many businesses, but knowing when to upgrade can be tricky. On the one hand, staying up to date ensures security, performance, and compatibility. On the other, upgrading too often can be expensive and unnecessary. So, when should you make the move—and when is it safe to stick with what you have?

Understanding SQL Server’s Lifecycle

Microsoft SQL Server follows a predictable 10-year support lifecycle:

• Mainstream Support (First 5 Years): Includes feature updates, bug fixes, and security patches.
  

• Extended Support (Next 5 Years): No new features—only security updates.
  

• End of Life: No updates at all, making it risky to keep using.

For example, SQL Server 2014 is no longer supported. If you're still running it, it's time to upgrade. SQL Server 2019 also recently left mainstream support, meaning it only has security updates moving forward.

Reasons to Upgrade

1. Your version is no longer supported
   If your SQL Server is out of support (or approaching it), you’re no longer getting security updates, leaving your system vulnerable. SQL Server 2016 will reach the end of extended support soon, so plan to upgrade before that happens.
   

2. You need new features
   Each new version of SQL Server comes with performance improvements, security enhancements, and new capabilities. If these features benefit your business, upgrading is worth considering.
   

3. Your vendor requires it
   Many third-party applications rely on SQL Server, and vendors often drop support for older versions. If your critical business software no longer supports your SQL version, you’ll need to upgrade to stay compatible.

When You Can Stick With What You Have

If your SQL Server is still in mainstream or extended support, and you don’t need new features, you may not need to upgrade right away. However, it’s good to have a plan in place for when support ends.

Final Thoughts

Upgrading SQL Server isn’t just about staying current—it’s about security, compatibility, and performance. If your version is nearing the end of its lifecycle, it’s time to start planning your move.
