Check out the upgrade docs at http://www.microsoft.com/ad and the readme
that comes with your 2003 server media for more specifics.
You won't coexist, you'll insert a 2K3 DC into your 2K domain/forest. As for
DNS, DHCP, and WINS, the migration is a little different.
DNS - If AD integrated, install on the new DC at installation. Let
replicate.
- if not AD integrated, then you'll have to replicate the zone to the new
server.
- recommended to ad-integrate if that works the domain you have.
WINS - WINS replicates. Replicate it to the new instance. Change the
client settings before sunsetting the old WINS replica. Be sure the clients
have started using the new instance.
DHCP - no replication :( you'll have to migrate it. There are tools to
help, but it takes some time while you update the client settings. It's not
overnight neccessarily.

Thanks for the advice! Excuse my ignorance, but how do I upgrade the
schema, while I'm installing the WIN2K3 server? Ditto for migrating
FSMOs.
Does it mean that I would have a 2K and 2K3 AD domain coexisting for a
while until I remove 2K AD?
When you said move DNS, WINS, DHCP, you meant Just installing them on
the new server, right?
Did you also have to migrate Exchange (from 2K to 2K3) by any chance? If
so, in what sequence you did the upgrade?
Thanks

I would, if budget allows, go the second route. Do the schema upgrade
bring up new windows 2003 server. Migrate FSMO roles to it. Move
DNS,WINS etc to the new server and then DCPROMO, one at time, your other
servers out. Reinstall them with W2K3 and dcpromo them back in. Did this
with a 700 user network with no downtime.

Peter Johnson
P.S
Look out for the article on migrating your DHCP database.

Subject: [ActiveDir] AD Migration Question
I have a W2K AD that I want to migrate to W2K3 AD. What's the best
option: In-place upgrade of the W2K DC or standing up a brand new W2K3
DC server
And then upgrade the W2K DC to W2K3?
By the way the W2K DC is also running DNS, DHCP, & WINS. I have one more
DNS server. If I go the second route do I need to set up a DNS server or
can I use the existing ones?
Thanks
