Upgrading to Exchange SE
Hi,
I currently have Exchange 2019 and need to upgrade to SE. When attempting an upgrade the process didn't appear as expected.
Articles I've read basically said the process should be the same as a regular CU upgrade.
When I run setup from the ExchangeServerSE-x64 iso, I get an Add Server Role window, instead of the expected upgrade method.
The window presents 3 Roles, 2 are ticked, and they're all greyed out. The Next button has no function.
I have Standard Edition 15.2 2562.17 (CU15). When checking my build number online, it is listed as the SE version, released July 1st, 2025.
When I run Get-ExchangeServer, the Edition = Standard. Should it not say Subscription, or maybe SE? How do I verify my installation is actually SE?
Thanks
Hi SteveJD,
15.2 2562.17 is the SE RTM build number. You can track all Exchange Server release information at https://learn.microsoft.com/exchange/new-features/build-numbers-and-release-dates.
It looks like you're re-running Setup using SE RTM, which is why it does not look like an upgrade.Exchange Server SE is available in four Editions:
- Enterprise, which supports a maximum of 100 mounted databases per server.
- Standard, which supports a maximum of 5 mounted databases per server.
- StandardEvaluation, which is a 180-day time-limited Standard Trial Edition.
- Coexistence (aka Hybrid Deployment), which maintains the hybrid relationship with Exchange Online.
So, the output you see from Get-ExchangeServer is showing you the correct Edition.
Unfortunately, this can be confusing because SE also uses the word Edition in its name, but these are two different things (one is simply the product name, and the other is determined by product key).
You can verify your installation specifics using the https://aka.ms/exchangehealthchecker, or by running the following PowerShell command on your Exchange server:
Get-Command Exsetup.exe | ForEach-Object {$_.FileVersionInfo}Hope this helps!
