migration to appliance

Hi,

Hope you all doing well.

We have an old solution netbackup master 7.7.3 on solaris sparc server with 4 medias.

The new solution installed is a netbackup appliance 5250, netbackup version is 9.0.

The customer asks if it is possible to migrate a part of backups to the new solution (appliance) and keep the rest with the old one.

In this case, what will be the workaround? 

Thank you in advance for your clarifications.

    Hi Riadh_R17 

    Firstly the catalog migration from your existing master to the appliance a complex task typically which can only be done by Veritas consulting (although StoneRam-Simon may also have a method). 

    As for the remainder of your questions:

    • Yes you could run both masters at once (although it would not be recommended and could get confusing).
    • If you have migrated the catalog, then why do you need the old master running anymore? 
    • What is your intention for the old media servers - a media server can only be attached to one master server?
    • Using hosts files instead of DNS for this purpose again would work, but I can see challenges around making sure the hosts file on a particular server is using the correct entries.

    What is your actual goal - why do you want to keep the old master server running? Will you be upgrading this to a supported NetBackup version? If you do a complete catalog migration, there should be no reason to keep the old master running (and the existing media servers can be moved to the new master as part of the migration).

    Hey

    What do you mean parts of backup? Current clients? Or already made backups? If second one where backups were written to? Disk or tape? if disk - what kind of storage server was used?

    If to tapes - read about importing backup images here 

    https://www.veritas.com/support/en_US/article.100017201#:~:text=NetBackup%20media%20may%20be%20imported,Phase%201%20and%20Phase%202.&text=Creating%20a%20new%20pool%20called,backups%20from%20using%20these%20media.

    If it is about to move clients to new NBU domain - it should be easy. Create for these clients policies on new one as these were on old (of course storage units will be different), add in old NBU domain to these client new master/media server into servers for these clients... than I would upgraded the clients and make the newly added master as master ;)

      Hi quebek 

      Thank you for your answer.

      can you explain more clearly these steps ?

        Hello

        I am not sure what is unclear there... Please read NetBackup Admin guide part 1 and you should know what to do.

        These are the basics NBU administration tasks. Can you perhaps be more specific?

    It is possible to do many different things but we do need to have a better understanding of what is is that you are asking.  (NetBackup migrations, is all I do!!  and  I've been doing them for more than 13 years).

    Partial migrations can mean many different things depending on who is reading it..

    it can mean migrating just policies, 

    it can mean migrating just legacy images on tape (in which case media import is possible)

    it could mean moving individual clients, and their policies, and images, and other related configuration.

    If you are looking to migrate everything related to a given client, you need to prepare for such a migration by moving all associated images, and policies to use on of the media servers and make sure that any disk or media is not shared with other clients that are not being migrated. 

    If a partial migration, requires you to also move media servers or storage you will need to make sure that post migration these components can be upgraded to a supported version for the destination (in your case something that is supported by 9.0).

    If you can elaborate a little more to state what the desired end result should look like, myself (or others) may be able to give a more defined response as to how to achieve it.

      Hi StoneRam-Simon 

      Thank you for your answer

      knowing that we only work with hosts files (no DNS), after wholy migration of the catalog from old master to new master

      is it possible to let the two masters turning on ?

      we think editing hosts files of some clients to point to the new master. is it possible ? or we should point all clients to new master ?

      for example:

      Client A and client B are using the old master, is it possible that after migration of catalog,  we keep client A running with old master and just edit the hosts file of client B to use the appliance as its new master?

      Sorry if i wasnt clear.

      And thank you for your time and for your explanations
