I am preparing to do an in place upgrade of our Windows 2000 Server that runs Exchange 2000 (hey, we can't afford an additional server, unfortunately... non-profit world and all) to Server 2003 and Exchange 2003.  I've done Server 2K to 2K3 Upgrades, and Exchange 2K to 2K3 Upgades, but never before on the SAME box, in a production environment - so I want to be sure I'm not camping out, having to run a clean reinstall and tape restore over the weekend!  Admitidly, it's been over a year since I did any types of upgrades like this, so I figure it's best to refresh myself with the help of the experts here, and helpful resources via Google.  :)

I've read through the MS white papers and also found a handy 'checklist' of sorts at http://www.commodore.ca/windows/windows_2003_upgrade.htm.

I know I have to upgrade Exchange first.  I found what looks to be a nice step-by-step procedure at: http://www.msexchange.org/tutorials/Upgrade_Exchange_2000_to_2003.html

I think maybe I'm confusing myself with all these white papers and various 3rd party documents.  I know in Q325379 (http://support.microsoft.com/?kbid=325379) it mentions having to create and run a script or Exchange will get 'mangled'...  

Now, my big question is: If I upgrade Exchange first, before the Win2K3 Server upgrade,  I shouldn't have to worry about any of that (script), correct?  Basically, I was planning:

1) Upgrade Exchange to 2003, according to http://www.msexchange.org/tutorials/Upgrade_Exchange_2000_to_2003.html.

THEN...

2) Upgrade to Server 2003, according to http://www.commodore.ca/windows/windows_2003_upgrade.htm


am I on the right track here?

You have to upgrade to Exchange 2003 first because Exchange 2000 doesn't run on Windows Server 2003 (http://support.microsoft.com/?kbid=321648)

Get a good backup before and after the upgrade.
Make sure your OS and Exchange are upgraded and patched to the latest updates

1. Upgrade to Exchange 2003
2. Run ADPrep /forestprep then /domainprep
3. Upgrade to Server 2003

http://www.msexchange.org/tutorials/Upgrade_Exchange_2000_to_2003.html as you mentioned above lists some pretty decent steps in order to migrate.

I'd say you are on the right track!
