I have a single domain running 2 W2k DC's and 1 W2K3 server running Exchange 2003. I have 2 new server W2K3 member servers that I want to promote to DC. After this is done I would remove the 2 W2K AD's and run with the 2 W2K3 AD's for a few weeks to ensure that everything is OK. After 2 weeks I'd raise functionality on both W2K3 AD's.
Is this the correct path? For some reason it seems to easy.
