Remove Exchange 2007 servers...

Hi

We have a mail platform with Exchange 2007/2013. We are going to delete the Exchange 2007 servers (all mailboxes are already in Exchange 2013) with the help of the following note: https://www.veritas.com/support/en_US/ Article.TECH50256

When doing step 3 (Look up EV's record of mailboxes associated with this ExchangeServerIdentity) we find thousands of entries corresponding to mailboxes that no longer exist. After consulting,  support tell us that we must delete the ExchangemailboxEntry table, which would leave us with the historical information of elements that no longer exist, and that we need to perform other tasks that we have automated.

Has anyone else been through this? It seems incredible that this is the only solution (obviously we can not leave the servers on Exchange 2007 turned on, and we need this historical information).

Thanks and regards.

  • Hello,

    Advocate of the devil here :-)

    EV does what it is supposed to do. Remove the entries connected to a server you want to remove. It is not EV (Veritas's) concern you target that specific table with custom queries/processes. They (Veritas) need to make sure that the product functions as intended, and performs well.

    End advocate of the devil :-)

    You have 2 choices as far as I can tell. Make a copy of the table (or the directory database) and target that in your processes/queries.

    Or, leave the targets in. Remove the tasks for those targets, but leave the targets. As long as the target Exchange remains, the ExchangeMailboxentry table is not having records deleted. It does not matter if the target exists physically (or virtually now-a-days) in the network. Just leave the name in the console.

     

  • Hey folks,

    From experience, you can upgrade (you can even leave the Exchange 2007 tasks). The only thing is that EV 12 will not be able to archive from Exchange 2007. This is the only limitation.

  • Hi mate,

    This means that you still have mailboxes in Exchange 2007. Have you triple-checked that all of them have been moved to Exchange 2013?

    If you are sure there are no mailboxes left behind, you can safely go to the next step, delete the MSMQ related to Exchange 2007 servers and remove them from the VAC.

      Hello

      I am 100% sure that all the entries that appear after doing this query are of mailboxes that no longer exist in the system and that all the active mailboxes are already in Exchange 2013. Those entries correspond to mailboxes that no longer exist, of users which do not exist in Active Directory either.

      If I delete the Exchange servers the entries in that table will be deleted, and I'm not interested in it. I need to keep historical information due to automated processes that I have, and rely on both the ArchiveID and the mailbox name.

        I may be wrong, but I don't think the entries will be deleted.

        To test you can do the following. Set backup mode, take a backup of the database and give it a try. If it really removes the entries, you can restore the database back.
