moving FSMO roles from Svr2003SP1 domain to Svr2003 R2 servers
I have a domain setup (before my arrival) that is 2003 SP1. I am adding 2 domain controllers to the domain that are 2003 R2. I want to move the FSMO roles from the 2003SP1 dc's to the 2003r2 dc's. Does anyone know if this would be problematic? Or, should I build 2 2003sp1 dc's and then move the roles and upgrade.
Any ideas would be great!
