I'm migrating an NT domain to Windows 2003 with AD. The NT box acting as DNS server will be removed, but I would like to leave it active so users can continue to log into the NT domain while I complete the setup of the new servers.
I've already installed DNS service (without AD) on the new W03 machine and created secondary forward and reverse lookup zones, setting the NT box to forward to this new secondary server. I want to promote the W03 DNS server to primary DNS with AD and demote the NT box to secondary DNS server.
1: Can an NT server be a secondary DNS server if the primary DNS server has AD integrated?
2. Which machine should I change first? Should I demote first (so briefly both are secondary) or promote first (causing both to be primary briefly)?
