Hello
I have a big trouble with mailbox migration.
Situation is: I have orphaned child domain with Exchange 2007 SP1 (root domain was disconnected and destroyed year ago). I need to migrate user accounts with mailboxes to a new domain with Exchange 2010. Trusting was set between domains. User accounts migration successfully tested with ADMT 3.2, but i'm stuck with mailbox movement.
I can't upgrade old Exchange server (2007 SP1) to SP3, because this needs schema update, but no Shema Admins and Enterprise Admins group in the child domain.
I can't export user mailboxes into PST files for future import to new server, because old server is 64-bit.
I set up Exchange management tools on the new 32-bit server, but i can't start neither Exchange management console no exchange powershell, because got "Could not find any global catalog in forest ..." error.
Any help would be greatly appreciated!
