G Suite is a web-based set of productivity applications from Google. It is a brand of cloud computing, collaboration tools, software and products developed by Google. To know about more features of it, you can visit here.

Here, in this blog, we will see how to migrate the emails from one G Suite account to another. The detailed documentation is available on their site but it creates confusion and quite difficult to understand it because all steps don’t have described on the same page. So, instead of switching pages, what if all the pieces are on the same page? It would be very easy to understand and implement it. Right?

Let’s start then!!!

Note: Before start the migrations, make sure you are logged in with new G Suite Admin Credentials.

Step – 1: Setup the Data Migration Service

  1. In your Google Admin console
  2. Go to Data migration app.
  3. Select the Email option and click Continue.
  4. On the Email Migration screen:
    • From the Migration source list, select G Suite.
    • From the Connection protocol list, select Auto select.
    • Enter the role account information for your old administrator’s G Suite email address and password.
  5. Click Connect to start the migrations. It will detect your old G Suite account.

Step – 2: Configure the Migration Setup

  1. In the next screen, we can select the Migration start date and options based on requirement. I have select Past 1 year. So, the email will migrate of last one year to till date.
  2. There is one option to select our custom date as well. So, we can migrate between those date ranges.

Step-3: Select User(s)

We can migrate one or more than one user accounts at a time. To do this we would need to follow the below steps.

  1. Complete the above steps to set up the data migration service.
    • Click on “+” icon and select multiple users.
    • Click Attach file to upload a CSV file containing the legacy email addresses and the new G Suite email addresses and passwords. Click Upload and start the migration.
  2. We can see the status on migrations Dashboard.
Select User

That’s it!!
