Does Source and Destination Restore host should be on same version of NBU?

Dear Experts

#Due to some reason one of our environment still is on 6.5.6#

My question is ,  IF we are trying to restore ORACLE database to some Linux host , which got Netbackup version 6.5.3 , but when the ORACLE database backups it was different Linux host which had Netbackup version 6..0 MP6.

So is that possible to restore to some other host which got higher version Netbackup on it?

Source : 6.0 MP6

Destination : 6.5.3

Master/Media server : 6.5.6

Is oracle restore possible or do we need to downgrade Destination to 6.0 MP6 as well?

If yes, how do we downgrade?

Regards!
