dataset error after upgrade

Hello, we have recently upgraded our Protection Manager from dfm 4.0.2 to OnCommand 5.2.  We installed a fresh OS and made a backup of the old DFM and restored it to the new OnCommand server.  From what I can tell everything seems to be working fine.  However there is one dataset the takes snapshot backups to another Netapp that is failing.  A similar data set with the same relationship but with different volumes is successful.  I do not see much details in the logs about the failure except that there was an error. 

Here is a sample email of the error;

An Error event at 15 Jun 17:39 PDT on Qtree nofs3_nofs3_users on Volume nofs3_backup on Storage System nofs0.ltx-credence.com:

Hi Marc,

    I just confirmation from our folks internally that bug 624459 affects qtree snapmirror as well. Pls open a case with netapp and reference this bug to them.

Also to find the problematic file, follow the public report for bug 624459 in the link that I gave in my previous reply.

Regards

adai
