Exchange SE: The Simplicity of an In-Place Upgrade from Exchange Server 2019
Posted On September 1, 2025
Why Exchange SE Makes Upgrades Easier Than Ever
With Exchange Subscription Edition (SE), Microsoft's latest evolution in their Exchange Server line, an in-place upgrade is possible. This is literally just a rebranded, Exchange 2019 CU16. Which is why an in-place upgrade is available. Because it is just another Cumulative Update (CU) installation.
Conclusion
If you want to stay supported on your current Exchange on premises environment, then Exchange SE's in-place upgrade capability is available. It's a practical, efficient, and cost-effective path to a modern Exchange environment. Just do it. I know some people don't want to, but it's easy if you're on Exchange Server 2019.
