Move FSMO roles from 2003 AD DC to a 2008 DC
Posted on 2013-06-24
We have a total of three DCs on our network. They all replicate fine. The DC currently holding all 5 roles and is a Windows 2003 R2 server. We have another 2003 R2 server that replicates with it. We added a third Windows 2008 R2 about 6 months ago and all DCs replicate without issue.
I want to move all 5 roles to the existing Windows 2008 R2 server. The Domain and Functional levels are Windows Server 2003. I still want to keep all 2 DCs operational, and simply want to move the roles onto the newer Windows Server 2008 R2 server. In the near future we will implement more W2K8 R2 servers, and we simply want to make the existing W2K8 the new main server holding all the roles. All three servers are Global Catalog servers with Active Directory DNS configured.
How can I move all 5 roles to the existing W2K8 R2 server? I still want to keep the existing W2K3 server holding all roles in mixed mode since I still have W2K3 servers that need to continue replicated AD services.
Is it a matter of connecting to the existing W2K8 R2 server, and simply right clicking on the domain name in Active Directory Users and Computers, All Tasks, Operations Masters..., Change button for RID, PDC, and Infrustructure. Then going to Active Directory Domains and Trusts, and right click on Active Directory Domains and Trusts, selecting Operations Master..., and select change for the Domain naming operations master. That's the way it was done when all W2K3 servers were deployed, but I am not sure if it applies with W2K8 R2 servers in the mix. I did not see anything pertaining to the Schema Master, but I think it was updated when the W2K8 DC was joined to the domain six months ago.
