    I am not 100% sure on this so cation is needed - consider to open a support request with Veritas

    Before starting the operation obtain the media id for the now gone data domain. Media is @aaaa{something}.

    Try using the -nodelete to the bpexpdate command.  bpexpdate -nodelete will remove images from the catalog but not try to delete the image itself.

    See : https://www.veritas.com/support/en_US/article.000117798

    Subsequent you need to clean up the EMM table as it keep track of images it can't delete. The -fore option to nbdelete will remove the image from EMM, deletable or not.

    /usr/openv/netbackup/bin/admincmd/bpimage -cleanup -allclients
    /usr/openv/netbackup/bin/admincmd/nbdelete -allvolumes -force

    Verify afterwards clean up is complete by running 

    nbdelete -deletion_stats [-U] -media_id name (name is @aaaaa{something} again.

    Also check the image clean job in Netbackup.

I have been wondering since my reply why the compatibility issue was not picked up before the upgrade?
Or if the DD cannot be upgraded?

since the DD is no longer needed i was not aware of the "need". I thought i can just delete :(

so this means i have to upgrade DD, install the plugin and connect...just to cleanup my database

    No you don't have to - but it quite a mess to do the clean-up afterwards :-D

      thanks Nicolai

      so i did a "bpexpdate -stype DataDomain -dp dd-de-dp -nodelete" which was working fine. Then i checked again for the images
      [root@franbp1 ~]# bpimmedia -stype DataDomain -dp dd-de-dp
      no entity was found
      [root@franbp ~]# bpimage -cleanup -allclients
      [root@franbp ~]# nbdelete -allvolumes -force
      [root@franbp ~]# nbdelete -deletion_stats -U -media_id @aaaah
      Frags : 0
      KB    : 0
      [root@franbp ~]#

      And next cleanup was running fine no longer partially successful :smileyhappy:

      But i do not understand what means "quite a mess to do the clean-up afterwards" ? I am missing anything ?

        "Quite a mess" is the reason why you requested assistance in this discussion. 

        This process is not automatic and not documented since this issue should not present itself with proper planning.
