    Hi Saurabh,

       I haven't done it yet. I'll update the discussion after I've finished. I have also contacted Symantec Support and they gave me a slightly different approach which I'm going to test early next week, meaning:

    1) nbemmcmd -addhost –machinename "newmediaservername"–machinetype media -masterserver masterservername -netbackupversion 6.5.6 -operatingsystem linux

    2) nbemmcmd –listhost                     (to confirm that it has been added to EMM)

    3) nbdecommission –oldserver "oldmediaservername" -newserver "newmediaservername"

    4) Uninstall media server software and install media server software with the desired hostname (newmediaservername).

     

    Your comments, please.

     

    Thanks,

A - You should remove and reinstall netbackup since after decomissioning it, the server is no longer part of the netbackup domain. It is the cleanest way to do things.

B - For the decommission you should use -oldserver <server to be removed> -newserver <server that will take ownership of all backups and media> This MUST be a valid server that is part of your NetBackup domain. 

C - This is the part that can be a bit interesting. You need to know which backup IDs to move back. Then you can run bpimage -newserver master -oldserver media -id <backupid> 

Also note this can be more difficult if there is an MSDP on the old server. You need to duplicate those images to another server and expire the images on the old server BEFORE decommissioning the server otherwise the decommission will fail.
