Hi, I'm trying to prepare our Server 2008 r2 to migrate from exchange 2003 to 2010.
When trying to do a PrepareSchemaif fails running ldifde.exe and it exits with code 110.
Only 1 forest
Exchange 2003 is in native mode.
Attempted this on my DC server 2008 with account that is part of the admins group.
I have checked and no firewalls are turned on, and I have all virus protections turned off.
DCDIAG tests all pass.
I have ran a Pre-deployment Analyzer and the only issue is that Active Directory Schema needs to be upgraded (which I'm attempting to do obviously).
