This should be an easy one for some of you guys with DC and AD experience.
I am introducing a new DC running 2008R2 to replace a DC I have running 2003. I have run through all the set up and I have the new 2008R2 (DC-04) running alongside the existing 2003 domain controller (DC-03), I also have another 2003 DC (DC-02) which I am leaving alone.
Since I have this DC-04 up and running with 2008R2, I was planning on shutting down DC-03, and renaming DC-04 to DC-03 so it replaces it. After some research it seems this may cause some issues since the DC-03 name already exists in my system.
What is the best course of action here, is there a good way to clear out all references to DC-03 and then rename DC-04 to DC-03?
Or is it better to just demote DC-03, shut it down, and leave DC-04 with the name it has now? Will computers in my domain know to look to DC-04?
Any help is greatly appreciated, Thanks!
