Small network. I just installed two new 2008 R2 domain controllers. Both are GC's, and I have transferred over the FSMO roles from one of the old 2003 domain controllers to one of the new 2008 domain controllers. I have changed DNS on all servers, and have also moved DHCP to one of the new 2008 servers. About 5 days ago, I unplugged the network connections from the old 2003 servers for testing....All seems to be just fine.
Before actually plugging the old 2003 DC's back in and decommissioning them, I noticed that our 2003 Exchange Server is still pointing to one of the old 2003 DC's in the Recipient Update Services.
Is it safe to go ahead and right click on those and change the server that RUS is pointing to, to one of the new 2008 DC's?
After that, I think I'll be all set to decommission the old 2003 domain controllers, and then(in the next few months), transition to a new 2010 Exchange server...
Thanks in advance.
