We are in the process of migrating users and their PC's from one AD Forest [Forest A] to a new Forest [Forest B], all servers and resources will remain in the original Forest [Forest A]. Currently the DHCP Server [Windows 2008R2] is in Forest A when finished the user migration I want to migrate the DHCP server from Forest A to Forest B. What is the best way to do this?
Should I create a new Server in Forest B then migrate the settings with the DHCP migration tool to the new server.
or
Should I unauthorize the DHCP server in Forest A then migrate the server to Forest B and then authorize it again?
