We are days away from upgrading our domain to a Windows 2003 Active Directory. This is how I propose to perform the upgrade
We have the following scenario
1 X NT4 PDC
1 x NT4 BDC
1 x Windows 2003 Server which hosts Pri DNS and which will be the eventual main DC, FSMO master
1 x Windows 2003 Server which hosts Sec DNS and which will be the second DC
I have already created the neccesary zones, namely,
all zones support dynamic updates
So, when I upgrade our PDC, DNS setup will complete without a hitch using the existing DNS server. I will then run dcpromo on the Pri DNS once I am happy with the upgrade.
Anyway, this is my question. The zones above are all Standard Primary on the Pri DNS server with the Sec DNS Server listed as additional nameserver. Should I
1) Set up secondary zones on the Sec DNS server then once I have promoted both servers to DCs change the zone types to AD Integrated
2) Leave the zones just residing on the Pri DNS server. Then, once I have promoted the first server, change the zone type to AD integrated and then promote the second.
I know it probably seems like a very subtle distinction, but I would appreciate some input.
