Beginning with Data ONTAP 7.2.5.1, qtree SnapMirror resynchronization is not supported for mirroring volumes from a less strict qtree to a SnapLock Compliance qtree. When the source is a non-SnapLock qtree or a SnapLock Enterprise qtree, and the destination is a SnapLock Compliance qtree, resynchronization is not allowed.
The following table shows all the possible combinations and whether resynchronization is allowed.

In addition, to allow a qtree SnapMirror resynchronization between SnapLock Compliance qtrees, you must make at least one transfer from the SnapLock Compliance qtree source to the SnapLock Compliance qtree destination after you upgrade to Data ONTAP 7.2.5.1 or a later release and before you break the relationship. If you do not make the transfer after the upgrade, the resynchronization is disallowed.
