If your migration seems to be taking longer than expected, please see the troubleshooting section of this article.

    Warning:

    Your destination mailboxes must be created prior to migration. See our articles Adding Multiple Mailboxes in Premium Business Email and Hosted Exchange.

    Note:

    You can close the browser window while this is being performed. The amount of time it will take depends on the number of mailboxes you are migrating and number of emails contained in them.

Troubleshooting Migration Issues

The number one cause of an email migration taking an excessive amount of time is the size of the migration. Migration of mailboxes that are between 350MB and 1.5GB can take up to an hour, and groups of mailboxes can take even longer. When you migrate, it should be done outside of business hours when incoming and outgoing emails are slower.

There are additional factors that can slow down the migration process, the most common are:

  • Simultaneous mailbox migrations: The self-service migration tool uses MigrationWiz, this tool reaches over 1.5GB per hour per mailbox when connecting to high availability infrastructures. Migrating more mailboxes at the same time allows parallel processing and can reduce the duration of your migration.
  • Network speed: The network speed at both the source and destination servers is a factor in the speed of your migration. The slower the network speed, the slower your migration.
  • Network latency: Network latency depends on the quality of the connection between the source and destination servers.
  • The number of mailbox items: Mailboxes containing large amounts of messages and attachments will take longer to migrate. The source and destination servers talk to each other to introduce each message, so a mailbox with several messages will have more network chatter than a mailbox with one large message.
    Note:
    Prior to migration, make sure your users go through their messages and delete any non-essential email items that they will not need. This will help speed up your migration.
  • Mailbox size: The volume of data in a mailbox can affect the length of your migration, the number of items in a mailbox has a much greater impact on the duration.
  • Mailbox errors: Errors can occur for many reasons, including corrupt items and network outages. MigrationWiz contains automated self-healing technology that can automatically manage errors for you in most cases.
