Prerequisite Step: Setting Up Data Migration Services for Office 365 to G Suite Migration

As the Data Migration Service is going to conduct the export process from O365 to G Suite, we need to prepare it for the process.

  • First of all, users have to sign in to the Google Admin Console with the administrator account. Remember: Administrator account id does not end with @gmail.com.
  • The home page of Admin Console will open. Navigate to Data migration from there by clicking on More control.
  • Click on Email>> Continue.
  • At this point, the Email Migration screen will appear. Here, you have to perform these actions:
  1. From the list of Migration Sources, select between Microsoft Exchange and Office 365 mail server according to your actual legacy environment.
  2. Afterward, choose an option from the below to select the connection protocol of your “legacy mail server”
    Select Autoselect to have the protocol getting determined automatically. (This is the recommended step by Google.)
  • If you want to include the Exchange Web Services URL by yourself, you have to select the Exchange Web Services option. Then type the URL, which is the address that is used by Exchange to contact Exchange Web Services. One such example is:
  • Firstly, Add your role account credentials like email address and password.
  • Secondly, Click on the Connect button.
  • If it fails to connect, check if the information regarding the role account and connection protocol is correct. Finally, click again on Connect.
  • Users have to accept all the default options of two sections named “Migration start date” and “Migration options.” Else, they can choose the data that do not need export.
  • Click on Select Users.
