WooYing,

You are on the right track here. I would bring the new hardware into the
NT4 domain as a BDC. Transfer the PDC role to the new hardware and do an in
place upgrade to Windows 2000 or 2003. Now, you'll have AD with the NT4
server as a BDC.

Transfer your database to the new server. If its MS SQL, I'd say detach and
re-attach the database and Log files. If you can't have any downtime, set
up a publication relationship and transfer the user connections to the new
server. If its not MS SQL, you're on your own <G>.

>From here, make sure you don't have anything mapped or dependent on the old
server (DHCP, Printers, File Sharing, other apps) and decommission the old
server.

There are other options and ways of doing this, but I think its the safest
with the smallest potential impact to your users.
