Cross-forest Exchange 2007-2013 new-moverequest fails

Dear.

Source forest has Exchange 2007, target forest is Exchange 2013. We have a bidirectional forest trust, we ran the prepare-moverequest.ps1 script successfully, but I get the following errors when executing the commands:

[PS] C:\>New-MoveRequest -Identity 'email address' -TargetDatabase "DB01" -remote -RemoteCredential $RemoteCredentials -RemoteHostName ex06.accent.local -RemoteGlobalCatalog dc102.accent.local

The call to 'https://ex06.accent.local/EWS/mrsproxy.svc' failed. Error details: The underlying connection was closed: The connection was closed unexpectedly. --> The underlying connection was closed: The connection was closed

[PS] C:\>New-MoveRequest -Identity ‘DN’ -TargetDatabase "DB01" -remote -RemoteCredential $RemoteCredentials -RemoteHostName ex06.accent.local -RemoteGlobalCatalog dc102.accent.local

The requested search root 'accent.local/Users' is not within the scope of this operation. Cannot perform searches

Thanks for the support.
Regards.
Peter
