I've been trawling through the reams of information on the web about migrating from NT4 to server 2003 and none of it has been able to answer one of my concerns.
We're a smallish company with about 75 employees, but we have 5 branches scattered about the state. At the moment we have one PDC in the head office along with 3 BDC's, and a BDC at each of the branch offices.
Because of the scattered nature of the offices, I can't upgrade all the servers at the same time and need to be able to stagger the upgrading of the servers starting with the head office.
My plan is to upgrade the PDC first, but I'm concerned that once the PDC is running Server 2003 and Active Directory, I won't be able to make it talk to the other servers. This would be a major problem because the PDC is currently running DHCP and DNS and is, well, the PDC, it not talking to the rest of the network would be bad.
Is there any way to run a combination Server 2003/NT4 network, or should I approach this in a different way?
