I have a one, simple domain with 4 DCs (2 older 2003 DCs and two brand new DCs). I am trying to moving the role of DC from the old hardware to the two new servers with new hardware. I have all four 2003 servers up and operating as DCs. But from what I understand the one older DC (let's call it DC1) handles the FSMO role. If I want to eventually demote DC1 as a domain controller and reformat the HDDs, I need to make one of the new DC servers handle the FSMP role? How do I do that? Are there any other considerations or any other things that need to be migrated to the new server?
