Dunno for sure if this also is valid for the upgrade to 7.3, but part of the revert_to process used to be deletion of snapshots which were made using the uprev ONTAP version.
This usually means you have to either delete all snapshots, or delete a few by hand, which can cause you to have to resync snapmirror/vaults.
Good luck on the reversion, and let us know how it went?
Thank you! FYI, the migration we discussed back in July (and which,for other reasons, was postponed to Nov, 8th) did go well.
We actually believe it is possible to transparently (without NFS service interruption) migrate data between filers without using virtualisation technologies, but this would require some modifications to the way snapmirror migrate functions. So we had to plan some downtime.
We wanted to suggest those to NetApp, but let's say we have some other problems for now ;-)
