Migrating from Zimbra RRS feed

  • Question

  • Hello Everyone,

    I'm evaluating best tools to migrate from Zimbra to Exchange 2013.

    So far I've seen Cloud Migrator 365, Softspire Zimbra converter and Migrationwiz.

    Has any one tried any of the tools above in a similar scenario? What's the best? any advice or issues to watch for?

  • I used BitTitan MigrationWiz to move about 8,000 mailboxes from Zimbra to Office 365 for one of our university customers last year.

    A few salient points and recommendations:

    - Something you need to be mindful of in all IMAP migrations is that if you have users that have mounted shared calendars, they should be disconnected prior to migration, since a mounted IMAP calendar is frequently imported as a secondary calendar to the target mailboxes

    - If you are synchronizing an AD environment to Office 365, you will want to populate the AD objects with the SMTP proxy addresses on the user's Zimbra accounts and make sure that the users' UPNs match their primary SMTP address (which will fix a myriad of Outlook and Skype autodiscover issues)

    - I would recommend deploying an Exchange hybrid solution (single Exchange server, hybrid configuration wizard) so you can use either the Enable-RemoteMailbox or New-RemoteMailbox cmdlets as part of your on-going provisioning process.  On-premises hybrid will also give you TLS-enabled transport from on-premises applications relaying through it to Office 365 mailboxes, so on-premises mail won't get flagged as spam

    - Cloud mailboxes must be provisioned prior to mailbox data synchronization.  If you want to pilot users, you can using the script and methodology I provide here (  I built it for two of my Zimbra customers and it has been used in about 75 MCS engagements.

    - Export the permissions from Zimbra mailboxes and use the Add-MailboxPermission cmdlet in Office 365 to configure mailbox permissions going in.  It will make your life better.

    - If you are synchronizing from AD, make sure your Zimbra DLs are recreated in Active Directory as well (if you want to source them from on-premises AD).  Otherwise, recreate them directly in the cloud.  If they are recreated in the cloud directly, you can grant ownership rights to them, and users can self-manage the groups via OWA or Outlook.

  • No I never tried them but for migrating the data from Zimbra (TGZ) file the user should not go with the manual method according to my opinion as that process is tricky and risk full to perform. But you can try the software which I used earlier that is Softaken Zimbra Converter. This application is a great solution proved for me as it provide me direct conversion result and accurately. To get more information about this tool you can refer this link:-
