Move Master Netbackup 6.5.6 to 7.5 or more

Hi,

My client wants to change her Master Netbackup 6.5.6 to version 7.5.

Does the bd Netbackup EMM will follow?

If during the installation of the new Netbackup server, is that I can put the old database in the new Netbackup?
 

What other information the old Netbackup server Can I transfer to the new server?
 

Is there a procedure for changing the Master Netbackup an improved version?

Thanks
