We use file device classes for TOC. No problems. NFS mounted data domain storage. Maxcap of 400GB. We have several TB of toc data and don't have problems except for hating life when I have to do a restore. It works fine, just can be painfully slow if you have very large TOCs (file systems with 20million+ files)
I haven't looked into the v6 upgrade process yet, but I would try and pursue the standard upgrade for the library manager/NDMP instance, then use export for everyone else. I was under the impression the standard upgrade process would work for ndmp data.

Environment: AIX 6.1, TSM 5.5.4 We've been backing up a couple of NAS filers via NDMP for around 18 months but recently find that sending the data to a storage pool of 12 500G rlv-formatted disks has been diagnosed by L2 as the cause of occasional problems with the recovery log when it changes volumes -- holding the recovery log too long and crashing the instance. The rlv disk data has been moved off in preparation to rebuild the disks as FILE devclass volumes...but think I remember reading something about TOCs being troublesome/incompatible with that config? Since one of these NAS boxes has millions (literally, I'm told) of small documents -- versions of which are required to be kept forever -- TOC is a a 'must-have' for file level restore, else we would have to restore the whole filesystem, the largest of which has about 5-6TB in use. Is anyone using NDMP writing to file devclass with TOC successfully? (any suggestions on MAXCAP? default is 4M which seems 'small') Side issue: think I heard there's no data export upgrade path for NDMP...'take a fresh full backup' isn't going to work for millions of keep-forever documents...we are planning to move to AIX 7.1 and TSM 6.2.x later this year when the new hardware arrives so this will be upon us soon.
