Using Rainfinity as a migration tool to Netapp

This is re-posted from the Celerra group at the reccomendation of the support people there.

We currently are looking at migration methods for moving about 7 VDMs  worth of data to Netapp Vfilers.  We already have a Rainfinity in house  from when migrations were done from the stand alone file servers to the  Celerra VDMs.  Has anyone seen the Rainfinity used in this way?  Also,  is there an application that will copy over the local users and groups  from the VDMs over to the Netapp filer?
