I have NetWare 6.5 server with 30 licenses. I cant find any cd's with licenses so I would like backup them for future use. Is that possible?

Also how can I check what Service Pack is installed?

In NetWare Administrator tree i had item describing server and if I click on Details i had:
Novell NetWare 5.70.02

This server is used only for samba (sharing files over network), clients connect to this files via dos program (something like a database based on files). So is this worth to apply latest SP?

Also in few month's we migrating database to new oracle server.
