I'm beginning to introduce 2008 R2 servers into my 2003 AD Domain. The first
server I was planning on replacing was a 2003 R2 DC that was basically used
for file sharing and was a 3rd DC in my environment. I was planning to
replace it with a 2008 R2 DC for the same purposes but I'm concerned with
what will happen to my existing AD infrastructure.
If I plan on keeping my other (2) 2003 R2 DCs and my Exchange 2003 on a 2003
R2 server, while adding this single 2008 R2 server am I going to experience
issues if I DCPROMO it to DC status?
Will this convert my entire 2003 AD infrastructure to a 2008 R2 AD and will
I need to be concerned about the 2003 Exchange server?
I've looked around for posts regarding migration but I don't really see
where anyone else is only introducing one 2008 R2 DC. Everyone else appears
to be replacing all DCs at once.
Do I need to be concerned? Has anyone else done it this way?
