Excuse me for my poor English, I'm italian.

I have novell 6.0 service pack 5 and I'd like to upgrade to NW 6.5
service pack 6.
I don't change the hardware of my servers, I want only upgrade the s.o.
I have more servers with nw 6.0 sp5 how can I proceed ?

I have already checked the NDS health (tid 10060600).

I'm not expert so can you suggest the steps that I must follow?

thanks for all
