Re-use IP adr and Name of PDC after migration

Archived from groups: microsoft.public.win2000.setup_upgrade (More info?)

I just finished a new Win2003 server build on new hardware
which I intend to use to replace the existing PDC(AD). How
can I reuse the old server's name for the new server?
Also, how about reusing the IP address (old server is DNS
and DHCP server for the network)? After I take the old
server off the network it's easy enough but what about the
SID and the LDAP complications? I think I'm also in for
trouble with Office since the old server is the Admin
Install Point for the clients.

Haven't quite pieced the KB articles together enough to do
this...help!
