I'm in the process of upgrading my Windows 2000 domain to Windows 2003. I've already run adprep /forestprep and /domainprep with success.
I'm decommissioning the root DC and moving all services (DHCP, DNS, WINS, etc including all FSMO roles) to a new machine that will be the new DC. I have not promoted the new server to a DC yet.
I'm not sure how to handle moving DNS. Should I run DCPROMO on the new server and point DNS to the old server and then move DNS to the new server later? Should I move DNS to the new server now and then run DCPROMO?
I've read KB articles on how to move DNS within NT 4.0 or 2000 but not much on 2003. Also I've seen steps on moving the zone files over but they include having to move the IP address of the old DC to the new DC as well. I'm trying to avoid that if possible (may not be able to do that).
Any suggestions would be greatly appreciated.
