I have an very old DC with FSMO roles installed.
This is an old WIN2008 server, no R2.
Can I move the roles from WIN2008 to an WIN2012R2 server ?
And please can you give me some hints and links ?
It's advisable not to, but as long as the move is clean there isn't any downtime.... However.... If it goes wrong, you'll need to seize the roles, that could cause issues.
