Here is the issue
I have my First domain controller that is on windows 2003 R2 x64(is also my only Exchange 2007 install). I have a secondary domain controller that is windows 2003 x86 that I also has the GC on.
I want to add in a new (physical) domain controller 2008 to be my "primary" domain controller. I also plan to decommision my current secondary domain controller and create a 2 new 2008 domain controller inside my vmware clusters.
I'm not sure what the best recommendation is for what to do about the original first domain controller running exchange. I still want it to be my exchange server but don't need it to be a DC anymore. I assume if I demote it my exchange will get destroyed with it somehow. Will having that machine as a 2003 domain controller cause me issues with 2008 AD at all?
Any suggestions on my best course of action?
