Mailboxes wont move to Exchange 2013

Im currently attempting to move mailboxes over to Exchange 2013 from 2010. Upon creating the initial migration batch of 34 boxes, 31 failed and 3 system boxes completed. I then attempted to migrated a single mailbox and it completed without errors, however, the mailbox didnt actually appear to have been moved.
I get 0 Total 0 Synced 0 Finalized and 0 Failed.
When I view the details on the batch, it shows nothing.
Any ideas?
