I currently have 3 Windows 2000 Servers with SP4 and fully patched - the domain is still in mixed mode but I can easily go Native. I have Exchange 2000 SP4 on one server which happens to be the Operations Master and a GC server.
I have a new server which will has Windows 2003 std installed. I will be installing Exchange 2003 on this new server and migrating the email mailboxes to the new server. ( The reason for the upgrade is old hardware and low disk space on the old Exchange server and needing a larger backup drive). It made sense to buy a new server to accomplish these objectives.
My question is :
Is there an order I need to follow to install the new 2003 server without breaking AD or Exch 2000 until I can get the email migrated and Exch 2000 uninstalled?
Sounds like I have to:
Run ADPrep and ForestPrep on the existing 2000 domain operations master
Can I just join the new server to the 2000 domain and then run dcpromo to install AD and ugprade the domain to 2003 or do I have to upgrade an existing 2000 server to 2003 and then add my new server?
