Netbackup Upgrade from 6.5

Hi All,

I need some light with an upgrade for one of my new clients.

They are running(amongst many), a Netbackup domain with the following setup:

Windows 2003 Standard Edition, Service Pack 2

X86

Physical Memory 4.095.08MB

Virtual Memory 7GB

Netbackup version 6.5 (No patches).

5 of thier other sites are currently running on 7.5.0.7 and one site on 7.6.0.1

They would like to upgrade this smaller neglected site to the latest version.

Should I advise them to start with an upgrade to 6.5.5 then possibly to 7.0.1 or I can just upgrade to 7.0.1 ?

Thanking you in advance.
