We are going to starting the process of upgrading our server OS soon from Server 2008 to 2012 R2.
We have 3 servers running 2008, one is the PDC, another is file and SQL server and last one is Exchange 2010.
I know the adprep needs to be run on the PDC, do I run this on the Exchange server as well? If so, is there anything I need to look at for or any special attention that needs to be directed at the Exchange?
How have your experiences been with the migration?
