- Already installed 2022 on most of my servers. I have a few though that I can't complete the in-place upgrade from 2019. It fails on reboot with an error and rolls back. Whenever I ask for help the response I get "not recommended you should rebuild" but the upgrade is a supported scenario right? See https://learn.microsoft.com/en-us/answers/questions/916816/server-2019-)-2022-in-place-upgrade-failure for more details.

Hi Brian, Could be issue I have seen possibly. It first occurred back in June of 2022. It was fixed in November of 2022. Make sure you are using the December or later Windows Server 2022 ISO and you have dynamic update enabled when you run setup Setup.exe /auto upgrade /dynamicupdate enable- Thanks, that worked! Got the latest ISO and my servers that wouldn't upgrade have now done so.
- Finally, we do have good updates on Windows Server 2022. Let's have fun.
