Regarding the upgrade of Netbackup Clients

I have a query related to the upgrade of clients.

We have upgraded the Master Server, Media Server and few clients from 7.1 to 7.5.0.4 version.

We have a mix of clients like AIX, Solaris, VMWare, Linux and some Windows clients.

Now I want to upgrade the Clients from 6.0 versions to 7.5.0.4 version for all the clients across the Infra.

Kindly provide me the documentation/ web link to verify the compatibility with the OS versions/Hardware/Processor etc., and the Netback up Client version.
