Migration mailbox between two MBX - Error - Exchange 2010

Hi,

We have an Exchange with CAS/HUB/MBX role and recently I reconfigure another Exchange that previously has the CAS/HUB role into a Mailbox.

When I try to move a mailbox between the CAS/HUB/MBX and the new MBX I get this error:

Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:22
xxxxxx
Failed

Error:
Failed to communicate with the mailbox database.

MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80004005, ec=2423)

Exchange Management Shell command attempted:
'XXXX.local/Users/CXXXX2' | New-MoveRequest -TargetDatabase 'MBX-XXXX'

Elapsed Time: 00:00:22

Then I do the same with PS and -Verbose and get this log:
