Decommissioning a MediaServer

Hi,

I have a Netbackup 6.5.6 Environment with a clustered Masterserver and 8 Mediaservers (All Windows 2003 x64).

All backups are made to DataDomain OST Storage Units.

Because we are migrating to Netbackup 7.5 (Reinstalling), we would like to decommission the mediaservers one by one, as we are installing the new environment.

The server I would like to decommission is SRV012 (It is still running fine and doing backups at night)

How do I correctly remove SRV012, whilst reassigning the existing images on my DataDomain to an already existing mediaserver that will NOT be deleted (SRV007)?

How do I use the NBDECOMMISSION tool correctly?:

1) NBDECOMMISSION -M MASTERSRV00 -oldserver SRV012 -newserver SRV007 -file output.txt
2) NBDECOMMISSION -M MASTERSRV00 -oldserver SRV012 -file output.txt

Will all backups done by SRV012 be available still? Will everything on the DataDomain be reassigned to a different mediaserver?

Any help will be appreciated!

Thanks!
