hi belgrade44,

thanks post.

your dcs in same domain , site?

if so, when can install new server, run dcpromo on , allow replicate new dc. if dns ad-integrated, don't have anything, replicate automatically just make sure to install dns role on new dc. dhcp, can import/export database.

as planning decommission old servers, need transfer fsmo roles, dhcp etc new server.

note - can identify fsmo role dc information using netdom /query fsmo command.
