NBU 7.6 Oracle Agent Install

Hi All,

Im planing on upgrading toda a MASTER/MEDIA server on Windows and a Solaris Client with Oracle agent, so my question is:

What is the correct way to upgrade the client?

Should I re-run the nbu script for RMAN?

Whitch should be the state of the DB while Im upgrading the client?

Thanks for the help

Alejandro
