I have one win2k forest root DC, 1 NT 4 bdc, and one 2000 member server. I wish to make the 2000 member server a dmoain controller (no problem i know) But how can I make it the new forst root? The old forest root is due to be retired pretty quick.

The NT4 BDC will sit there doing not much of anyhthing except letting users log in and is fine just the way it is.

(Obviously this is mixed mode)

Essentially, just add the new DC using dcpromo, and then move all of the FSMO roles and GC to the new box. You can do this manually (there are several articles covering this at http://support.microsoft.com just enter "move fsmo role") or do it automatically by demoting the current DC using dcpromo (after you have promoted the replacement, of course). The demotion process calls "Give Away FSMO Roles" and it searches the AD looking for the next suitable host. I always move the roles manually myself, and I have multiple boxes acting as DCs to spread them around. Read up on this before you do anything.
