Reinstalling server from NW 6.5 SP7 to OES2
Want to keep a NSS volume in a local RAID0 unharmed, including eDir file rights

We're about to reinstall a NW 6.5 SP7 server to OES2.
In addition to the SYS volume, this server has a separate local NSS volume in the RAID,
storing home directories, files and applications for the users.
If possible, we want to keep this volume including its file rights,
and reassign it to the new OES2 server object.

Is it possible to reinstall only the SYS-partition of the RAID0 to OES2,
leaving the other NSS-partition unharmed, and then reassign that NSS partition
to the new server object, while keeping the trustees/filerights?
