I have followed the MS recommended cross-forest migration process from Exhcange 2007 to 2010. However, after successfully running the Prepare-MoveRequest.ps1 and trying to perform the actual mailbox migration i get the following error:
"Parameter -RemoteTargetDatabase must be specified.
The command i am using, identical to MS's example and similar cases found here:
New-MoveRequest -Identity 'firstname.lastname@example.org' -RemoteLegacy -TargetDatabase 'Storage Group' -RemoteGlobalCatalog 'dc01.oldDomain.Old.com' -RemoteCredential $RemoteCredentials -TargetDeliveryDomain 'Mailboxserver01.newdomain.com'
Its almost as though its trying to migrate the wrong way (from 2010 to 2007). If i do as it says and change targetdatabase to remotetargetdatabase it give my the obvious 'Source user 'test3' doesn't have a primary mailbox.' which further enforces my theory.
