Exchange 2007 Cross Org Mailbox Migration
Paul MacKnight has written a post about cross organization move mailboxes in Exchange Server 2007.
Cross-org Mailbox Moves
Cross Org migrations are the ones where a mailbox needs to be moved from one Exchange Organization to another. Since there can only be one Exchange Organization per Forest, that means moving the mailbox between two different Forests.
Exchange Migration Wizard was used to perform this task in Exchange 2003. Exchange 2007 has incorporated Cross Org migrations into the server code base, so now Administrators can perform these moves by using the same task used for Intra Org migrations: Move-mailbox.
The following versions are supported for this kind of move:
Source Server:
- Exchange 2000 SP3 (or later)
- Exchange 2003 SP1 (or later)
- Exchange 2007
Target Server:
- Exchange 2003 SP1 (or later)
- Exchange 2007
Exchange Permission requirements:
- Logon account for the user who is running Move-Mailbox needs to be a granted the “Exchange Recipient Administrators” role for Source and Target Forests and “Exchange Servers” role for both source and target Server. Permissions for legacy Exchange Servers remain the same as they were for Exchange 2003 Migration Wizard.

The source AD needs to be Windows 2003 in order to use cross-mbox move as I found out recently. There are a number of articles out there that talk about cross forest moves from EXCH2000>EXCH2007 - but none mention the requirements for Active Directory.
If you try to move when all source DC’s are Win2K, you get:
The Error message:
Domain Controller ‘lima.contoso.com’ Operating System version is 5.0 (2195) Service Pack 4. The minimum version required is 5.2 (3790) Service Pack 1.

Any idea how to solve this error message:
>>>>>>> Start Error
Failed to reconnect to Active Directory server serverA.SourceForestA.tld. Ensure the server is available and that you are using valid credentials.
At line:1 char:1

Hi,
I have to following setup:
* Exchange 2003 server SP2 which is DC/GC (Windows 2003 SP2) in SourceForestA
* Exchange 2007 server SP1 RU3 in TargetForestB
* I have an account in both forests that has sufficient permissions on Exchange and on Active Directory
* I’m using Get-Credential to fill the variables.
