Google Workspace (Formerly G Suite) Email Migration


Many users who wish to use Google Workspace to manage their business applications may already have a fully functional email that has already been in use and may store a large amount of email essential to their business. Google Workspace has tools to directly migrate your email to your new Google Workspace email account.

This article discusses the following topics.

How to Migrate Email to Google Workspace (G Suite)

  3. Click Set Data Migration Up.

    Google Workspace - Set Migration

  4. On the next page, fill out the necessary fields.

    • Select the type of source server you are migrating from – Choose I don't know / Other IMAP Server.
    • Select the type of items to migrate from your source server – Choose Email from the dropdown.
    • Connection Protocol - Select IMAP from the dropdown.

How to Troubleshoot Common Email Migration Issues

The two most common issues that may cause a migration to fail are the following:

Google is trying to transfer the email too quickly

If the transfer fails after you have already had a successful connection, please try to adjust the migration speed.

To adjust the migration speed:

  1. Click the down arrow beside More.
  2. Select Migration Settings.

    Google Workspace - Email Migration - Migration Settings

  3. Use the slider to adjust the speed for your simultaneous requests.

    Google Workspace - Adjust Migration Speed

    Note: It is recommended to set the migration speed to half the number of users you are trying to migrate. For example, if you are migrating 100 users, set the speed to 50. Otherwise, leave the migration speed to its default value of 100. Do not select a speed larger than half the number of simultaneous requests your source server can handle to prevent putting much load on your mail server.
  4. Click Save.


You're connected to the incorrect server

If you are getting incorrect emails from the transfer, you may have connected to the incorrect server.

To change which server you have entered for a user:

  1. Click the down arrow beside More.
  2. Select Exit Migration.

    Google Workspace - Exit Migration

  3. Click Exit Migration to confirm.
  4. You will need to restart the migration process and enter the information for the correct server your email is hosted on, as instructed in Step 4.
