Upgrade to Netbackup Version 7.1 from 6.5.1

Hi,

I need some information.

one of my client is using netbackup version 6.5.1 on windows 2003 master/media server and also all netbackup physical clients, database, exchange and virtual machine servers are in same version 6.5.1

Now, iam going to configure new media server with Netbackup version 7.1, with existing master/media server with netbackup version 6.5.1, so I need to upgrade master server also with same version 7.1,

my question is,

I will upgrade master server 7.1 from 6.5.1, is there any other changes need to be done ? and it won´t affect backups for  netbackup physical clients, database, exchange and virtual machine servers with version 6.5.1 ?

Thanks
