Migrating your email from your server to Liquid Web’s Premium Business Email is made easy with our free self-service migration tool. From your browser, navigate to https://liquidweb.selfmigration.com and follow the instructions below. If your migration seems to be taking longer than expected, please see the troubleshooting section of this article.

Migrate Your Email

  1. When you open the website for self migration, enter your email in the Migrate section, agree to the terms and click Login.

    Your destination mailboxes must be created prior to migration. See our articles Adding Multiple Mailboxes in Premium Business Email and Hosted Exchange.
  9. After you enter the mailbox information to migrate, click Next and the migration tool will perform a trial migration to verify that the mailboxes are configured properly. Click Next to begin the trial migration.


    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.
  10. Once the trial migration is complete, a success message will show and you can proceed to the next page.

  11. Once the trial migration completes successfully, you can now start the migration process, click Next to migrate your mailbox(es).
    begin migration
  12. When the migration begins, you will be able to see the progress in the Status section. You can navigate away from this page during the process as it could take some time depending on the number of mailboxes and amount of data in them before your migration is complete.

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.
    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.
