MSDP conversion

Hi all,

some weeks ago I upgraded Netbackup from 7.7.3 to 8.1 for a customer.

During the installation, the system didn't asked me about the MSDP conversion process.

The upgrade was completed without issues. How can I check if the MSDP is ok?

Thank you

    There are quite a number of docs that deal with pre-upgrade steps, pre-upgrade EEB, MSDP pre-conversion steps, post-upgrade EEB, etc. 
    Hopefully you have gone through all of that?

    https://www.veritas.com/content/support/en_US/doc/25074086-127355784-0/v122375353-127355784

    To determine the mode of data conversion and the conversion progress, use the --dataconvertstate option:

    Windows: install_path\Veritas\pdde\Crcontrol.exe --dataconvertstate

    UNIX: /usr/openv/pdde/pdcr/bin/crcontrol --dataconvertstate

      Hi Marianne,

      thanks for replying.

      I already checked with these commands and this is the output:

      ./crcontrol --dataconvertstate
      ***** Data Conversion *****
      Status : ON
      Mode : Fast
      Busy : Yes
      Current Group ID : 15043
      Current DCID : 15404071
      Min Group ID : 0
      Max Group ID : 15425
      Progress : 18%

      I also checked it with this command and seems that everything is ok

      ./stconv --status
      Your Media Server Deduplication Pool is up to date

      But maybe I found the answer to my question.

      I read in this page https://www.veritas.com/content/support/en_US/doc/25074086-127355784-0/v122375349-127355784  that after the upgrade to 8.1, the data is re-encrypted with the AES-256 algorithm, so the data container has an additional .map file that contains the mapping between the SHA-512/256 and the MD5-like fingerprints.

      Before posting this question, I checked only the last data container and there weren't .map files, but, in the previous data I can find them. That means that it is converting and everything could be ok.

      Anyway, I still have the doubt about the fact that I was not asked about the conversion during the update, both from 7.7.3 to 8.0 and from 8.0 to 8.1. Next week i have to perform another similar upgrade. Are the command I used above (crcontrol --dataconvertstate and ./stconv --status) enough to be sure that is ok?

      Thanks again

        There is also 
        crcontrol --fpconvertstate 
        Not sure if the pre- and post upgrade EEB's are necessary for this switch as this option does not appear in Commands Ref Guide.

        Output should look similar to this : (From  https://www.veritas.com/support/en_US/article.100045193  )

        Monitor conversion until completed: 

        # /usr/openv/pdde/pdcr/bin/crcontrol --fpconvertstate
