Manual Method to Migrate from Google Workspace to Microsoft 365

Microsoft 365 offers an official migration path for organizations transitioning from Google Workspace. The process requires configuration across both platforms before migration begins. You need to follow the steps below to migrate Google Workspace to Microsoft 365.

Step 01: Prepare the Microsoft 365 Domain

1. Access the Microsoft 365 Admin Center using a valid administrator account.
   
2. After that, you need to simply add and verify the primary domain.
   
3. Add a routing subdomain to manage mail flow during the coexistence period.
   
4. Create user accounts and assign active Exchange Online licenses to each user.

Step 2: Prepare the Google Workspace Domain

1. Log in to the Google Admin Console.
   
2. Add the same routing subdomain as a User Alias Domain.
   
3. Navigate to Apps >> Google Workspace >> Gmail Settings, and enable IMAP access under End User Access.

Step 3: Configure Google Cloud Platform

1. Go to the Google Cloud Console and create a new migration project.
   
2. Create a Service Account and download its security key in JSON format.
   
3. Enable the Gmail API, Calendar API, and Contacts API within the project.
   
4. In the Google Admin Console, access the Domain-Wide Delegation settings under Security > API Controls.
   
5. Authorize the Service Account Client ID with the OAuth scopes required by Microsoft.

Step 4: Create the Migration Endpoint

1. Open the Exchange Admin Center and navigate to Migration, then Migration Endpoints, then New.
   
2. Select Google Workspace as the migration type.
   
3. Enter the Google Workspace super admin email address & upload the JSON key file from Step 3.

Step 5: Start and Run the Migration Batch

1. In the Exchange Admin Center, go to Migration and select Add Migration Batch.
   
2. Choose Migration to Exchange Online and select Google Workspace Migration.
   
3. Upload a CSV file mapping source Google email addresses to target Microsoft 365 usernames.
   
4. Select the endpoint created in Step 4, set the target delivery domain to the routing subdomain, and start the batch.

Step 6: Finalize Mail Routing and Clean Up

1. Once the mailbox status displays Synced, plan the cutover window.
   
2. Log in to the DNS hosting provider and update MX records to point to Microsoft 365.
   
3. Update SPF, DKIM, and DMARC records accordingly.
   

In the Exchange Admin Center, select the migration batch and click Complete Migration Batch to run the final delta sync.

After confirming email delivery, delete the completed migration batches.
