Bridgehead server

Question

I'm migrating my domain controllers over to new hardware with a new name and IP address. I have no bridgehead servers set at all in my domain when I look at sites and services. When I do a repadmin /bridgeheads it shows all my domain controllers I'm replacing as bridgeheads. My question is, since I don't have any set, when I demote my old domain controller, will it automatically select my new server as the bridgehead or do I need to set this before hand?

Answer 1

If that's the only other domain controller at the site then yes.

Answer 2

You don't need to do anything KCC process will nominate a new bridgehead from the remaining domain controllers at site.
