Google Workspace to Microsoft 365 Migration: Gmail, Drive & Calendar Transfer

Quick Answer: How do you migrate from Google Workspace to Microsoft 365?

To migrate from Google Workspace to Microsoft 365, you provision the Microsoft 365 tenant and users, pre-sync Gmail into Exchange Online while users keep working, move Google Drive files into OneDrive and SharePoint, transfer contacts and calendars into Outlook, then switch MX records and run a delta sync at cutover. Net Microtech manages the entire Google Workspace to Microsoft 365 migration with zero downtime and verified, no-data-loss transfer.

Many businesses standardise on Microsoft 365 for its Office desktop apps, Teams, and enterprise Exchange email. Moving from Google Workspace is straightforward when planned properly, but the mapping between Google and Microsoft services needs care — Gmail labels, Drive sharing, and Google Calendar all translate differently on the Microsoft side.

What Gets Migrated (Google to Microsoft Mapping)

Google Workspace Migrates To (Microsoft 365) Notes
Gmail Exchange Online mailbox Labels mapped to Outlook folders
Google Drive OneDrive for Business Personal files & folder structure
Shared Drives SharePoint document libraries Team/shared content with permissions
Google Calendar Outlook / Exchange Calendar Events, recurrences & invites
Google Contacts Outlook Contacts Personal & directory contacts

Our Google Workspace to Microsoft 365 Migration Steps

  • 1. Assessment: Inventory users, Gmail data size, Drive/Shared Drive storage, and shared calendars.
  • 2. Tenant Setup: Provision Microsoft 365, create users and licenses, verify the domain, and configure security (MFA, anti-spam).
  • 3. Pre-Sync: Copy Gmail and Drive data into Exchange Online and OneDrive/SharePoint in the background while users stay on Google.
  • 4. Cutover: Switch MX and autodiscover DNS records to Microsoft 365 during a low-traffic window.
  • 5. Delta Sync & Validation: Capture mail received during cutover, reconfigure Outlook and mobile devices, and validate every mailbox.

Common Challenges We Handle

  • Label-to-folder conversion: Gmail messages with multiple labels are mapped cleanly into an Outlook folder hierarchy.
  • Drive sharing permissions: Shared Drive access is recreated as SharePoint library permissions.
  • Large mailboxes: High-volume mailboxes are throttle-managed to avoid Google API export limits.
  • Calendar invites: Recurring meetings and external invites are preserved so nothing drops off the schedule.
