I'm not sure I see the problem. Given that one can internally (in ONTap) mount a volume pretty much anywhere in a custom namespace, one can almost use volumes like qtrees, just with a much better "container" for moving data in the background within the cluster. One just exports the volumes as part of the namespace. Admittedly, I haven't spent enough time with this yet to fully wrap my head around all the possibilities. I guess if you exported "hidden" directories below the old qtree level, you had a pretty quirky setup (although I've done CIFS shares a level or two below the qtree before. It wasn't very pretty though. Migration, if you mean from 7- to Cluster Mode, is pretty painful and the available tools really seem like lab experiments. Getting people over to cluster mode means migration for almost all of us but it doesn't look like that fact has hit home at NetApp yet. VTW was crude, MTT is actually perhaps even a bit worse. Given that NetApp wants to be a major SAN vendor, lack of migration tools for LUNs seems like a critical blindspot also. S.
