Migrating Netbackup media server from 6.5.4 to new Master server 7.5.4

Hi All,

Currently I am migrating two media servers from our legacy netbackup environment to the new Netbackup environment 7.5.4:

1. Windows 2003  media server which is currently version 6.5.4 to a new master server(Linux) which is at 7.5.4 version. It is attached to a tape library with two drives.  I have a few questions:

1. Do I need to upgrade netbackup 6.5.4 on the media server prior to be migrated to the new Master server? Do I need to upgrade the Tape library firmware/drives/ driver prior to migration?
2. Do I need to upgrade the Tape Library firmware/drives/driver prior to migration? (New master server?)
3. Do I need to perform the catalog backup on the old master server? I don’t think it will be required since the media server will be move to a new Master server.
4. Or  Can I just add the media server with the current version 6.5.4 to new Master server and then upgrade to 7.5.4?

2. Linux media server (Tape library will be partition with the new media server)
   1. What steps do I need to install a new media server with a partition tape library
   2. What kind of device driver do I need to install for the tape library and tape drives? The library is a Quantum IScalar Tape Library with 4 LTO tape drives?
   3. Steps required prior to partition the library .

Thanks in advance for your information
