I have an old Windows NT domain in need to upgrade to Windows 2000/2003 Active Directory. There is one PDC and two BDCs. What should my next steps be?
My approach would be:
Note that if you're planning on doing a hardware upgrade at the same time, then there would be a few differences.
If anything goes wrong before step 5, you can bring up a BDC, promote to PDC and keep using your NT4 domain until you've fixed the problem.
