Moving from Windows Server 2022 to 2025
And by moving I mean stand up a completely fresh Windows Server 2025 as the old server was patched for one too many times. (painfully slow and stuffy) What I figured out so far, is to install Windows Server 2025, and the exact same SQL Server 1:1 to the build # install ODBC v18 update current MECM to the latest and its OS (update other Microsoft products with windows update) go to sites / maintenance tasks and do an export robocopy the "software" folder as is Now next would be to shut down old MECM server, rename new to the old's hostname, and start the "recover site" What my concern is as always "What if" can I at this point or once I set up the new MECM up and running go back by shutting down this new server, and powering on the old (leave and rejoin domain for trust) and go back to business as usual? That if anything goes sideways, or things won't get better. By that i mean speeding up things which is the main reason of the 'move' which now I do not wish to troubleshoot. Our environment, database size is 7.9 Gb, which is far from being big. The reason must be the update over upgrade over update over 15 years or more no and never brand new OS. I can take care of the "how to" I know exactly how to recover a site 'on paper'. I just want to know there's no such thing as point of no return. (when not making a single change in the Db/console) I also understand I should not make any changes in the Db (console) while testing, which is no problem at all. All we use MECM for is staging computers. Nothing else really. Like nothing else at all. PXE. The end. Thanks for the inputs. (I hope I picked the right tags)
