Methods to Migrate G Suite to Office 365

There are two methods to migrate G Suite mailboxes into Office 365:
  1. Manual Method using the Admin Panel of Office 365.
  2. Automated Method using a third-party tool.

Using Office 365 Admin Center

1st Step – Sign in as an admin user in your Office 365 account.The admin is the only authorized user that can create and manage all the user accounts in Office 365.2nd Step – Check the Domain owner.For the migration of mailboxes from Google Apps to Office 365, you must first confirm that the domain is owned by yourself. You will go through domain verification while setting up Office 365.3rd Step – Adding Users to Office 365.An Admin can either add a single user at a time or multiple users at once using the CSV file. To add users, go to the Admin Center, click on Users > Active users and select the preferred option to add users. Make sure that each user has its own mailbox and license. Once done, pause the setup wizard and do not proceed with the “Set up Domain” step. It has to be done only after migrating the Gmail mailboxes.4th Step – Get the User List from the G Suite account.Admin must first reset the passwords for all G Suite accounts and create a temporary password to later include in the User list. The steps for creating the list are:
  • Log in G Suite admin console and click Users.
  • Keep the Google console open.
  • Now open Excel.
  • In Excel, input EmailAddress in A1, UserName in B1, Password in C1.
  • Now, use the user list from Google console to select each user account and enter the displayed username, email address and password in the Excel sheet.
  • Proceed to save the document as a CSV file.

  • Now, select the [] button and choose Migration endpoints.
  • Click the plus icon [+].
  • Choose IMAP from the select the migration endpoint type page.
  • Enter imap.gmail.com in the IMAP server and keep all the default settings, then click Next.
  • Give a name to the migration endpoint and click on new to create the endpoint.
6th Step – Create a batch and start G Suite to Office 365 Migration.Here, the admin user can try to migrate a smaller batch first to test the process execution. To start the batch migration, follow these steps:
  • In the Office 365 admin center, click Admin centers and choose the Exchange option.
  • Afterward, click on Recipients and select Migration.
  • Click the plus icon [+] and choose to Migrate to Exchange Online option.
  • Select IMAP migration and click the Next button.
  • Click Browse to locate the select the CSV file that you created in the 4th step.
  • Once the file is validated by Office 365, check the number of mailboxes it displays and click on Next.
  • Choose the migration endpoint created earlier and click on Next.
  • Again, click Next in the IMAP migration configuration page.
  • Now, enter the migration batch name and add folders for exclusion, then click Next.
  • Choose Automatically start the batch and click on new to immediately start the migration of G Suite mailbox to Office 365.
  • To verify the completion of the process, look for Synced status after going to Recipients, then Migration.
7th Step – Updating the DNS records.The admin must make sure that the MX records point to Office 365 and not Gmail. This will ensure that all the future emails are sent to Outlook account rather than Gmail. Create a TXT or MX record and request Office 365 to verify it:
  • Open Admin center.
  • Go to Settings.
  • Click Domains.
  • Select the domain name.
  • Select Start Setup and Verify.
8th Step – Stop the Synchronization.It can take up to 72 hours for email systems to recognize the changes in the MX record. So wait for this much time and then stop the synchronization between G Suite and Office 365. You should also ensure that every G suite user is now using Office 365 as the G suite mailbox will no longer be available.
  • In the Exchange admin center, go to Recipients.
  • Choose Migration and select the batch.
  • Choose Delete.

Important Points:

  • The Manual Method only works for Mailbox Migration.
