We are currently a single domain on a single network running Server 2003 Standard and Exchange 2007.
I have a new server up and running (added to the domain already) with Server 2008 R2 on it. I want this to become my Primary Domain Controller, thus replacing my old Server 2003 server.
I know I should just be able to run dcpromo on the new server, then decomission my old server, and raise my domain functional level to match the 2008 server. My only concern is the Exchange 2007 server. Is there anything I need to know relevant to it before I start? Thanks!
