Resume-moverequest problems when SuspendWhenReadyToComplete option has been used.

We are doing a cross forest migration and move mailboxses from Exchange 2010 to 2013.
We have done the new-moverequest with the option SuspendWhenReadyToComplete(over 30 days ago).

Now when we tries to do a Resume-moverequest, but we get TransientFalure on all moverequests we have tried.

Is it true that the SuspensWhenReadyToComplete expires after 30 days (Deleted mailbox retention time)?
