Migrate Gmail to Office 365: Step-by-step guide

Migrating from Gmail to Office 365 is a common need for both individuals and organizations seeking to leverage Microsoft’s productivity suite. This guide covers the entire process, including both manual and automated approaches, ensuring you can select the method that best fits your requirements.

Manual Way to Migrate Gmail to Office 365

Migrating Gmail to Office 365 manually involves several steps and requires careful preparation. This method is suitable for those who want to avoid third-party tools and are comfortable with technical configurations.

Key Preparation Steps:

• Plan and Prepare:
  Decide whether you need to migrate only emails or also contacts, calendars, and Drive files. Create a migration timeline based on the number of mailboxes and data volume. Back up critical Gmail data before starting the migration to prevent data loss.

• Verify Domain Ownership:
  You must verify to Microsoft 365 that you own the Gmail domain. This is essential for organizations using a custom domain with their Google accounts. If you don’t have a custom domain, you can use the default companyname.onmicrosoft.com domain provided by Office 365.

• Add Users in Office 365:
  Create user accounts in Office 365 for each Gmail user you wish to migrate. Assign the appropriate licenses to these accounts67.

• Prepare a List of Gmail Users:
  Prepare a CSV file listing all Gmail mailboxes to be migrated. Include each user’s email address and app password (note: Gmail requires an app password for IMAP access; regular passwords will not work if 2-step verification is enabled).

Step-by-Step Manual Migration Process:

1. Domain Verification:

   • In the Office 365 admin center, verify your domain or use the default domain if you don’t have a custom one76.

2. User Creation:

   • Add users and assign licenses in the Office 365 admin portal.

3. Enable IMAP in Gmail:

   • Log in to each Gmail account and enable IMAP access in settings.

4. Create App Passwords:

   • For each Gmail account, generate an app password to be used during migration.

5. Prepare Migration File:

   • Create a CSV file with Gmail account details (email addresses and app passwords).

6. Create Migration Endpoint in Office 365:

   • In the Exchange admin center, set up a migration endpoint to connect Office 365 to Gmail via IMAP.

7. Create Migration Batch:

   • In the Exchange admin center, go to Migration > Add migration batch.

   • Select “Migrate to Exchange Online” and choose IMAP as the migration type.

   • Upload the CSV file containing user information7.

8. Start Migration:

   • Initiate the migration batch. Office 365 will connect to Gmail accounts and begin transferring emails.

9. Update DNS Records:

   • Change your domain’s MX records to point to Office 365, ensuring new emails are delivered to Office 365 mailboxes.

10. Stop Gmail Synchronization:

    • Once migration is complete and DNS changes have propagated, stop synchronization with Gmail.

11. Verify and Finalize:

    • Confirm that all emails have been migrated and users can access their data in Office 365. Back up any remaining data if needed.

Manual Migration: Pros and Cons

• Pros: No third-party software required; full control over the process.
