Mailbox and Archive Migration Options

A note on root migrations

Exchange migrations do not migrate from the root, as EWS only sees and migrates items contained in folders. To migrate items at the root, create a folder for these items, drag and drop the items into the folder, and then migrate as usual. 


Mailbox and archive migration options


  1. Perform a standard mailbox to mailbox migration

    This is considered a mailbox migration project.

    Leave the Advanced Options at their default options, i.e., "migrate to mailbox" for Source and "migrate to mailbox" for Destination. When migrating, you specify the Source and the Destination mailboxes.

    Note: Once migration is complete, you could set Office 365 archiving rules so that mail will be moved to the archive mailbox, but that will all occur post-migration.

  2. Perform a mailbox to archive migration

    We support migrating directly to an archive mailbox. In this case, you would enter Advanced Options for your project and select archives as the Destination, as in screen shot below. You would then save these settings and run your migration following normal procedure.

    Note: This would still be considered a mailbox migration. Therefore you would create a mailbox migration project and purchase mailbox migration licenses or User Migration Bundle licenses.

  3. Perform an in-place archive to mailbox migration

    In this case, when you create a project, you choose an in-place archive migration project.

    In this case, you would leave the Advanced Options at their default destination setting, "migrate to mailbox".

    Note: This requires User Migration Bundle licenses.

  4. Perform an archive to archive migration

    This is also considered an archive migration project.

    In this case, you would change the Advanced Option for Destination to be "Migrate to: Archive."

    ​Note: This requires archive licenses, rather than mailbox migration licenses.
