I have an AD site that has 3 subnets assigned to it. These are for 3 different buildings connected by fast WAN. We are moving the servers from one subnet to another including the domain controller (and DNS server) for that site. It runs Windows Server 2008 R2. I have changed the NIC on the server to point to another server in another site for DNS primarily now so my thinking is that we change the a and ns records on the other server, change the ip address of the dc and shut it down before moving it. Once up in the new location change DHCP scopes to point at the new address for DNS. (DHCP forwarding/relaying is enabled through switches) IT's DNS properties already listen on all interfaces and it only handles AD integrated DNS. Has anyone done something like this and are there caveats to this I am missing?
Thanks in advance.
