I currently have 3 DCs (windows 2003 Enterprise SP1), one of them is old, and running out of diskspace. I need to replace this DC as soon as possible. The roles that current server is holding are Domain Naming Master and Schema Master. The requirements are I have to keep the same server name and same static IP address for the new server. I just bought a new server for this project and the steps that I am planning to do is as follow:
Build the new server in the test environment with the same name and IP address
From the current server (DC) transfer the roles it currently holding to the other DC ( question here: when I viewed the Change Schema Master or Change Domain Naming Master screen, I didn't see the other DC name listed in the option. It shows the same server name as the current one, So how do I transfer?)
Assuming the roles trasnferring is done. Run dcpromo to demote this server. Bring it offline.
Bring the new one online with the same server name and IP. make it member of domain.
Run dcpromo and make it DC.
Transferring the roles back to new server.
DId I miss any steps or is this the correct ways to do it? What if the process doesn't go through as expected? Please guide me through
