Email Migration Guide: Exchange to Gmail or Gmail to Exchange
6 steps for a successful platform switch with zero data loss.
Evaluate your current setup
Document all mailboxes, shared mailboxes, distribution lists, contacts, calendar events, rules, and custom configurations. Identify third-party integrations and API connections.
Choose your migration method
For Gmail → Exchange: Use Microsoft's Google Workspace Migration tool or third-party tools. For Exchange → Gmail: Use Google Workspace Migration for Exchange (GWMME) or BitTitan MigrationWiz.
Prepare the target environment
Create user accounts, assign licenses, configure MX records, set up SPF/DKIM/DMARC, and configure sharing policies. Enable litigation hold or Google Vault if needed.
Run a pilot migration
Migrate 5-10 pilot users. Test email, calendar, contacts, and shared mailbox access. Verify formatting, attachments, and folder structure. Fix any issues before full migration.
Execute the full migration
Migrate in batches to avoid overwhelming the target system. Maintain both platforms during coexistence. Set up mail flow connectors for cross-platform email delivery.
Cut over and decommission
Update MX records to the new platform. Verify inbound/outbound email. Decommission the old tenant after 30 days (keep for rollback if needed). Train users on new platform.
