I have a NetWare 4.2 server (1GHz proc - 2GHZmem, 380Gb RAID 5) which is
the home directory for approx. 2000 users. A situation has come up where I
need to upgrade it to NetWare 6.5/SP2.

Will CIFS work on a traditional volume?

In testing a NetWare 6.5 server with a traditional volume (Vol1:), I
cannot browse nor access via CIFS without the NetWare Client32. I can
however access SYS which is NSS.

If CIFS will not work with traditional volumes, what is involved in
converting the existing volumes to NSS once the 6.5 upgrade is complete?
Will users lose rights, am I at risk of losing the volume, etc., etc...?
