ESX 5.5 or later compatibility

Hi,

We need to know how is the version of the Netbackup to support ESXi 5.0, 5.1 and 5.5. 

Actually we have Netbackup 7.5.0.1 in the backup host, Netbackup 7.6.0.4 in the Master and Netbackup 7.6.0.1 in another master. This host connected to the VCenter with ESX 5.0 and now the support of this VCenter upgrade to 5.5.

We will need to upgrade our Netbackup Masters and BackupHost?

Thanks.

Regards.
