Upgrading Netbackup Media server from 7.0.1 to 7.5.0.7

Hi,

We have suggessfully upgraded one of Solaris Master Server from NB 7.0.1 to NB 7.5.0.7  last week.

Now we need to upgrade our 2 AIX media servers from 7.0.1 to 7.5.0.7 .

For master server upgrade, we have taken precautionary steps like ( Running NBCC , Taking snapshot of /usr/openv/ , Taking catalog backup, Copying DR file, Deactivating policies...)

Is there any pre steps that we have to taken before upgrading  our 2 AIX media servers ?

Is NB 7.5.0.7 Media server upgrade is just similar to Master server 7.5.0.7 upgrade?
