I have a Windows Server 2003 with a domain name of: test.testdomain.com
I want to replace this DC with a new 2012r2 but want to know if I should rename the domain first and then promote a new domain controller or promote the new 2012r2 and then perform the rename process?
With my test VMs, I am running 2012r2 and no problems at all, whole rename process went very smoothly but I am not as confident with 2003. Any advice?
