A Manual Way to Migrate Gmail to Office 365

The Gmail to Office 365 transfer process is crucial for any organization or individual; performing the process with utmost care becomes important for the user. So, follow the given steps very carefully to avoid any uncertainty in the result:

Step 1. Domain verification

It is necessary to verify to Microsoft 365 that you own the domain you used for your G Suite accounts. Without verifying the domain, migrating Gmail to Office 365 may be delayed.

Note: Using your companyname.onmicrosoft.com domain that is included with the Office 365 plan is considered the alternate option instead of your custom domain.

Step 2. Add users to Office 365

Office 365 provides you with a feature to add users, either one or several users at a time. While adding the users, you also need to assign the corresponding license to them.

Step 3. Create a list of Gmail mailboxes for migration

To execute the task, you need to create a migration file that contains Gmail mailbox lists for migration along with the corresponding app password of each email. A migration file can also be created through Excel. Let’s delve into the steps to accomplish the task:

1. Login to the Google Workspace admin console with your administrator username & password and go to the Users option.
2. Copy the user’s email address.
3. Now, launch the Office 365 admin center & select Users > Active Users.
4. Further, open the Excel application to fill in the entries as shown:
5. Then, save the file in CSV format & close the Excel application.

Step 4. Establish a connection between Office 365 & Gmail

For successful migration, Office 365 needs to be connected with Gmail. So, for this concern, Office 365 uses a migration endpoint that establishes the connection between them for the migration. Follow the steps below to create a migration endpoint:

1. Go to Migration in the Exchange admin center.
2. Click on the Endpoints & go to the Add+ option to create a new migration endpoint.
3. On the Add Endpoint page, choose IMAP as the migration type & fill in the appropriate information in the following fields, like Migration endpoint name, IMAP Server & leave the remaining information as the default settings. Finally, click on the Create option.

Step 5. Create a migration batch & initiate Gmail to Office 365 migration

The Migration batch contains the migration file that we have discussed in the previous steps. So, for creating the migration batch, follow the given steps carefully:

1. Go to the Exchange admin center, tap on Migration, followed by the Add migration batch option.
2. In the Add migration batch, give a unique name to the batch & select Migrate to Exchange Online as a migration path. Then, click on the Next option.
3. Choose the IMAP migration as the migration type & click on the Next option on the Migration type page.
4. In the next steps, click on the Next option after ensuring that you have completed all the prerequisites.
5. Now, select a migration endpoint from the dropdown list in the Set a migration endpoint page & then click on the Next option.
6. Now, in the Add user mailboxes page, upload the user information by clicking on the Import CSV file option, followed by the Next option.
7. After selecting the suitable options, tap on the Next option in the Select configuration settings page.
8. By selecting the appropriate options for efficiently managing the migration in the Schedule batch migration page, click on Save > Done options.

Note: You can check whether the migration worked or not by going to the Migration option in the Exchange admin center. If the status is Completed, then migrated successfully; otherwise, recheck the associated mailbox status for specific errors.

Step 6. Update your DNS records to route Gmail directly to Office 365

For delivering email, email systems use a DNS record called an MX record to figure out the location. While in the migration process, usually, your MX record was pointing to your Gmail system. But to complete the migration process, it is needed to point your MX record to Office 365.

Follow the given steps to update the DNS record:

1. Login to Office 365 with your work or school account.
2. Tap on the Setup followed by the Domains option.
3. Choose your domain & then select Fix issues.
4. Choose What do I fix? for each DNS record type & follow the corresponding instructions to add the records.
5. You will see a message that your domain is set up correctly (No action is required) once you add all the records.

Note: Wait for around 72 hours since your partner or customers take this much time to recognize the changed MX record.

This way, you can execute the Gmail to Microsoft 365 migration process completely.

• Synchronization errors due to incorrect IMAP settings.
