Exchange 2013 sp1 DAG problem on Wondows 2012 r2

Question

 Hi,
 I have configured this on my servers. It seems to be working almost 100%.
 When I look at  server-databeses in ecp  I see the DB is healthy both active and psssive.
 When I run  this (Get-DatabaseAvailabilityGroup) | ForEach {$_.Servers | ForEach {Test-ReplicationHealth -Server $_}}
 I get DatabaseAvailabilty   FAILED  on  both  active and passife  DB.
 When I Switchover to the other sever I get no errors  but in ca. 2 min it Switches back.
 If I try to move mailbox from Exchange 2010 sp3 to  Exchange 2013 sp3 I get 
Data migrated: 1.327 GB ‎(1,425,379,174 bytes)‎
Migration rate: 0 B ‎(0 bytes)‎
Error: MigrationPermanentException: Error: Mailbox changes failed to replicate. Database 18475dc2-2111-4da6-854b-6583d42c9279 doesn‎'t satisfy the constraint SecondCopy because the commit time 3/12/2014 12:17:49 PM isn‎'t guaranteed by replication
time 1/1/0001 12:00:00 AM.
I admit that I had this configured before I installed SP3 :( Do I need to delete the DAG and create it again?
thanks.

Hello,
Please use Get-MailboxDatabaseCopyStatus cmdlet to view health and status information about one or more mailbox database copies.
Based on your environment, please set DataMoveReplicationConstraint to None to check the result.
Set-MailboxDatabase "mailbox database name" -DataMoveReplicationConstraint None
After you have done the move, please set DataMoveReplicationConstraint to SecondCopy again.
Set-MailboxDatabase "mailbox database name" -DataMoveReplicationConstraint SecondCopy
