Demoting a 2003 Domain Controller and How Sites Are Affected
Posted on 2011-02-28
Adding and removing a new domain controller and have a question about any additional steps I need to take, beyond the standard ones.
The situation is a network with two AD sites. Each site originally had one domain controller. At one site, we are adding a 2008 R2 DC, and removing the old 2003 DC.
Poking around in Active Directory Sites and Services, I notice that there are replication links set up between the original two servers, and the old server and new server on the same site (but not between new server and old server on the different site). Do I need to do anything here (New Active Directory Connection)? I'm assuming so, since I'd like to shut off the old DC first, to test that nothing breaks. Looking at how things are now, there will be no replication if I do this.
Moving the FSMO roles won't be necessary, since those are on the lone DC at the other site. I've done (I believe) all of the dcdiag/netdiag testing, to test communication between Domain Controllers, and that all seems good.
