I have a 2003 Std Server setup as the primary domain controller and running dns and active directory on this as well. I also setup a second domain contoller and joined it to the existing domain contoller. Example mydomain.com(primary) & xxx.mydomain.com(secondary
). I want to eliminate the primary DC and make the secondary DC the primary and turn the current primary into another type of server. I have ran adprep as the primary is an older version of 2003. what is the correct procdure to make this happen and the best way to avoid down time to anyone joined to the domain?
