Microsoft 365 to Google Workspace Migration: Outlook, OneDrive & Calendar Transfer

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

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

Businesses move from Microsoft 365 to Google Workspace for its browser-first collaboration, Gmail simplicity, and Docs/Sheets real-time editing. The migration is reliable when planned properly, but Microsoft and Google structure mail, files, and calendars differently, so the mapping needs an experienced hand.

What Gets Migrated (Microsoft to Google Mapping)

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

Our Microsoft 365 to Google Workspace Migration Steps

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

Common Challenges We Handle

  • Folder-to-label conversion: Outlook folder hierarchies are recreated as Gmail labels so nothing feels out of place.
  • SharePoint permissions: Library access is remapped to Google Shared Drive membership.
  • Large mailboxes & archives: High-volume and archive mailboxes are staged to respect API throughput limits.
  • Recurring meetings: Outlook calendar recurrences and external invites are preserved in Google Calendar.
