How to migrate emails with Google?

Gmelius Updated by Gmelius

We suggest using the new Google Migration tool if you want to migrate emails across different mailboxes.

Requirements:

  • You need to have a Google Workspace account.
  • You need to have access to the Google Workspace Admin account.
  • Gmelius should not be installed and activated for the account used for the migration.

Important information:

  • No duplicate source users per CSV file (the target user can be added more than once).
  • It's not possible to launch migration in parallel. You must finish the first migration before starting a new one.
  • Do not have Gmelius installed.
  • 40'000 emails should take around 10 hours (it could be reduced depending on the size of your emails).

Step 1: Connect to the Google Workspace Admin account

To start the migration, head to this page with your Google Workspace Admin account: https://admin.google.com/ac/migrate/googleworkspace

The first step is to enter the email address of the Google Workspace Admin from your organization, and request authorization. Once authorized, you'll be connected to migrating email messages.

Step 2: Upload migration maps

The second step is to upload a CSV providing the user's source and target email addresses. You will find a sample CSV that you can download and use to ensure correct formatting on this page. Note that you can migrate up to 1000 users at a time.

Step 3: Configure migration settings

In this section, you can select additional settings for the migration:

3.1) Email start date: Select a start date for emails to migrate. Messages from the date that you select below to the day that you start migration will be migrated:

3.2) Email options: You can choose spam or deleted emails to be migrated as well. And even exclude emails part of a specific folder by adding a list of labels separated by a comma (e.g., Clients, Finance, Billing):

Step 4: Start the migration

Once you are ready to start your migration, simply click on the "Start migration" button:
