that might be VFM - which AFAIK is end-of-life  Rainer
I don´t know what product is it, but Netapp has something to migrate all windows users file shares profiles, from standalone windows file share host, to NAS without downtime and without user notice the changes. How to fight against this using some product hardware of software of EMC2. VNX has CIFS shares, and home directory options, but how to migrate especific user profile without notices of the owners folder any idea  MC:)
Compete against Netapp - with EMC2 how consolidate user file sharing without 
downtime, VNX?
