Microsoft 365 to Google Workspace

Leaving Microsoft for Google without losing the last ten years. Folders become labels, shared mailboxes become Groups, Teams become Chat spaces — and everything that can't be translated is written down, not dropped.

Typical moves.

Standardising on Google

An acquired Microsoft shop joining a Google-first company. Keep their mail history, drives and shared addresses; give them Gmail on day one.

Cost consolidation

Fewer suites, fewer licenses. Move the people, keep the addresses, retire the tenant.

A Google-native rebuild

Start clean in Workspace with the history you need and none of the SharePoint you don't.

In detail.

Mail → Gmail

Messages travel as standard MIME with dates, read state and flags; folders become labels; categories become labels.

Calendar & contacts

Events converted field by field including recurrence (Graph patterns → RRULE), reminders and free/busy; contacts to People.

OneDrive → Drive

Files streamed across; Office files stay Office files; sharing re-granted to the matched Google accounts.

Shared mailboxes → Groups

Each shared mailbox becomes a Google Group with the same address and members; its contents land in the Group's collaborative inbox where enabled.

Sites → shared drives

Libraries become shared drives with Owners / Members / Visitors mapped to managers / contributors / viewers.

Teams → Chat spaces

Channels merge into one Chat space with history imported under the original authors.

Copy 1 missing itemread-only on both tenants

Every container counted on both sides; the exact items that never arrived are listed and copied on request.

Good to know before you plan

Outlook rules, signatures and Teams tabs have no equivalent and are listed by name.
Recurring events with Exchange-only patterns are approximated to the nearest RRULE and flagged in the report.
Domain cutover moves the domain from Microsoft to Google with an MX/SPF check before you flip.

Six steps, one page each.

Connect both tenants, assess, match users, migrate in waves, verify and keep in sync, cut over. Every step lives on its own tab with the numbers that matter and the next action ready.
