Here's the scenario going on at our church...

3 servers, all running 2k.  2 of them are DCs, the other is just a
member server.  One of the DCs is already an Exchange 2000 server.

We received a donation of 2 nicely packed out servers.  We'd like to
re-purpose our existing hardware, so a migration seems to be in order
here.

Thus far, here's what I've done:

1. changed from Domain Mode to Native Mode on the AD, and verified that
the changes replicated to the other DC.

2. sometime after the work day's done today, I'm changing the Exchange
2000 from Mixed Mode to Native Mode and rebooting that system.

What I think needs to be done as next steps..  Feel free to slap me
about the head if I'm doing something stupid or leaving something out...

1. Install 2k3 Server on one of the new systems, make sure it's happy

2. On the DC that holds the Exchange 2k and the schema (since it's the
first 2k server that was installed, the schema is there, right?), do
what scenario #2 on mskb # 325379 says to do (make some ldif, run a
couple of commands from the command line, then adprep /forestprep and
adprep /domainprep)

3. Run dcpromo on the new 2k3 server, turn it into a DC

4. Install Exch2k3 on the new 2k3 server.
  - Do I install this as an additional server in the site?

5. Migrate mailboxes
  - How do I get the GAL, and other shared stuff to reside on the new
server?
  - How do I move the users' mailboxes over to the new server?
  - Do their Outlook clients get automatically updated to point to the
new server when they next startup?

What I've done thus far has been very simple and straightforward, but
the many kb articles and dozens of write-ups on the yet-to-do stuff, all
with different information make me long for the simplicity of openldap,
cyrus & postfix. :-)

Thanks for any pointers...
