So right now, I have two 2008 non-R2 servers acting as both of my DCs. These DCs are playing the roles of DHCP, DNS, and AD.
I need to decommission one of these physical servers and replace it with a new system, running Server 2008 R2 64 bit.
Do you know of any walkthrough helping me with this exact scenario? I'm having problems getting DNS to migrate gracefully. I feel that I have DHCP and AD already working, but I'd want to be completely sure.
My idea was that I can have all 3 servers up at once and then shut down one of the older DCs once I know the new DC is fully functional.
Also, once the project is done, does having two different DCs on two different Server 2008 versions matter? One serverwill be on R2, the older server will not.
