Mailbox migration failed after some successful batches

Hi,

I installed Exchange 2013 CU1 and I began to migrate my Exchange 2010 SP3 mailboxes. After a few successful migration batches using the EAC, I am currently not able to migrate any single mailbox!

I am afraid that the Exchange system is damaged. Is there any suitable cmdlet to test or repair the system? Unfortunately the BPA is yet not available...

Thank you in advance for any good idea!

Greetings, George
