I assume you are running the command from the Exchange Management Shell (not PowerShell) and you have been assigned a member of the Organization Management group.

Hi,
when migrating Mailboxes to a different Exchange-Server, be aware of Diskspace.
Whilst the Mailboxes are moving, Log-Files are created.
So if your Database has 130 GB, on the targetserver you need 130GB for the Database + 130GB for the Logfiles until you activate circular logging.
