New Netbackup 7.5.0.x on RHEL 6.4

Hi Team,

I am going to build a new Netbackup environment using Netbackup 7.5 runing RHEL6

I need your advice as per your experience.

Do I install Netbackup 7.5 with 0.5 patch or I should stay N-1, i.e. 7.5.0.4

same in case of OS RHEL 6 is now available with patch 4 i.e. RHEL6.4, Do I install RHEL6.4 or I should stay N-1 i.e. RHEL6.3

as per Netbackup OS compatibility guide, Netbackup supports RHEL6, its not mentioned as what patch level ...

Regards

Gurjeet
