Exchange 2007? Get those domain controllers upgraded!
Do you have to be running all W2K3 SP1 domain controllers in your organization before moving to Exchange 2007? No, only the DCs/GCs that will be used by E2K7 have to be W2K3 SP1 (though SP2 works just as well).
However, if the setup process finds a W2K DC/GC it will fail. And other processes (once you are in operation) such as Move-Mailbox will also fail. Here is another example:
Error: Domain Controller 'example.example.org' Operating System version is 5.0 (2195) Service Pack 4. The minimum version required is 5.2 (3790) Service Pack 1.
Exchange Management Shell command attempted:'28600b07-6d7c-4e94-9559-7861c88faa48' move-mailbox -TargetDatabase 'CN=Mailbox Database,CN=First Storage Group,CN=InformationStore,CN=EXAMPLE,CN=Servers,
CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=EXAMPLE,
Elapsed Time: 00:00:00
I am recommended as a prerequisite that people get their domain controllers upgraded to a minimum of W2K3 SP1 prior to starting their E2K7 migrations.
