Google Workspace to Microsoft 365 Migration

Migrating from Google Workspace to Microsoft 365 tenant includes discovery & assessment, pre-migration setup, domain migration, mailbox migration, file migration, post-migration cleanup, and documentation. The process begins with auditing Google Workspace, documenting DNS configurations, and inventorying shared Google Drive folders. It then moves on to creating users and assigning licenses in Microsoft 365, setting up migration projects, and configuring SharePoint architecture. Domain migration involves removing domains from Google Workspace, adding and verifying them in Microsoft 365, and reconfiguring DNS records. Mailbox migration includes configuring migration endpoints, pre-staging mailbox data, performing pilot migrations, and scheduling final cutovers. File migration involves planning file-to-library mappings, executing Google Drive migrations, preserving metadata and permissions, and conducting spot-checks. Finally, post-migration tasks include performing data integrity checks, providing training materials, documenting configuration steps, and delivering final documentation and sign-off packages. This comprehensive plan ensures a smooth transition from Google Workspace to Microsoft 365, addressing all critical aspects of the migration process.

Discovery & Assessment Audit Google Workspace for user count, aliases, and mailbox size Document existing DNS configuration and domain assignments Inventory shared Google Drive folders with their corresponding permissions Identify migration blockers and legal hold requirements

Pre-Migration Setup Create users and assign licenses in Microsoft 365 Set up migration projects and endpoints Configure destination SharePoint architecture (site/library structure) Schedule migration windows and notify users

Domain Migration Remove domains from Google Workspace Add and verify domains in Microsoft 365 Admin Center Reconfigure MX, SPF, DKIM, DMARC records Conduct test mail flow validation Create documentation to repeat the domain migration for additional domains.

Mailbox Migration Configure mailbox migration endpoints Pre-stage mailbox data (initial sync) Perform pilot migration and validation Schedule final cutover and run delta sync Verify delivery, calendars, mobile sync, and shared mailboxes

File Migration Plan file-to-library mappings (e.g., team folders → SharePoint Sites) Execute Google Drive migrations (via migration assistant tools) Preserve metadata and permissions Conduct spot-checks on migrated files

Post-Migration Perform data integrity checks and compare mailbox/file counts Provide training materials and sessions for end users. Document configuration steps, policies, and support procedures Deliver final documentation and sign-off package
