Microsoft 365 to Google Workspace Migration Services

Migration workstreams

More than a mailbox copy

Leaving Microsoft 365 changes how people sign in, share files, schedule meetings and find documents. We plan each of those, not just the data transfer.

Discovery

Microsoft 365 inventory

Users, groups, aliases, shared mailboxes, resource mailboxes, OneDrive and SharePoint volumes, Teams usage, and every app, device and automation that depends on Microsoft.

Mail

Exchange Online to Gmail

Mail, calendars and contacts moved in batches with a routing plan, so internal and external messages keep flowing while people move over.

Files

OneDrive & SharePoint to Drive

OneDrive content mapped to My Drive and SharePoint libraries mapped to shared drives, with folder structure, sharing and ownership reviewed first.

Identity

Entra ID & SSO

Accounts, groups, MFA and sign-in apps re-pointed to Google as the identity provider, with a clear plan for devices that were managed in Intune.

Cutover

DNS & mail flow

MX, SPF, DKIM and DMARC changed after a final sync, with a rollback plan and the Microsoft licenses kept until the move is confirmed.

Adoption

Training & support

Role-based quick-start guides for Gmail, Calendar, Drive and Meet, plus support in the days after cutover.

Where projects go wrong

The Microsoft-specific traps we plan around

These are the issues that most often surprise teams after a do-it-yourself move off Microsoft 365.

Teams

Chat does not come along

Teams chats and channel conversations have no direct Google Chat equivalent. We agree up front what is exported for retention and what is left behind.

Office files

Macros and complex Excel

Word and PowerPoint files usually open fine. Macros, Power Query and large Excel models do not convert to Sheets, so we flag them in discovery and keep them in Office format if needed.

Meetings

Teams meeting links

Migrated meetings keep their Teams links. Recurring meetings owned by key people are best re-sent as Google Meet invites.

Automation

Power Platform

Power Automate flows, Power Apps and Forms do not migrate. We list them early and rebuild the ones that matter with Apps Script or other tools.

Apps

Sign in with Microsoft

SaaS apps that used Entra ID as the identity provider stop working when accounts close, unless each one is moved first.

Licenses

Overlap and retention

Keeping Microsoft licenses long enough to verify the move, and long enough to meet retention needs, avoids losing mail you may need later.

Who this is for

This service fits organizations that have decided to move from Microsoft 365 to Google Workspace, from small offices to multi-site groups. Common reasons:

The team already works in Google tools and Microsoft is mostly used for email.
You are consolidating after an acquisition into a company that runs Google Workspace.
You want simpler collaboration and administration for a mostly browser-based team.
Licensing cost or product fit no longer matches how you work.

We are Microsoft 365 specialists, so we will also tell you if a smaller change, such as fixing licensing or governance, would solve the problem without a move.

What is in scope, and what is not

Usually in scope

Inventory of users, groups, shared and resource mailboxes, OneDrive and SharePoint data, Teams usage and Microsoft-dependent apps
Google Workspace setup, identities, licensing by role and MFA before anyone moves
Exchange Online mail, calendars and contacts migrated in batches
OneDrive to My Drive and SharePoint to shared drives, from a written mapping plan
Apps that sign in with Microsoft moved to Google as the identity provider
MX, SPF, DKIM and DMARC cutover with a final sync
Role-based quick-start guides and support after cutover

Handled separately or agreed during discovery

Rebuilding Power Automate flows, Power Apps and SharePoint site pages
Archiving Teams chat history or long-term mailbox retention
Moving Intune-managed devices to Google endpoint management
On-premises Active Directory or hybrid identity cleanup

How the work runs

Discover. Inventory Microsoft 365 and agree what moves, what is rebuilt and what is retired.
Prepare. Set up Google Workspace, identities, groups, mail routing and the file mapping plan.
Pilot. Move a small group, fix what they hit and adjust the plan.
Migrate. Move users and files in planned waves, with a final sync before cutover.
Cut over and support. Change DNS, confirm mail flow, support users and keep Microsoft licenses until the move is verified.

FAQ

Microsoft 365 to Google Workspace questions

Yes. We move Exchange Online mail, calendars and contacts to Gmail and Google Calendar, and OneDrive and SharePoint files to Google Drive and shared drives. We also re-point sign-in and SSO apps, cut over MX records and support users after go-live. Google Workspace was called G Suite until 2020; it is the same product family.

Teams chat history, Power Automate flows, Power Apps, SharePoint site pages and lists, Planner plans, Forms, and Office files with macros or deep Excel models do not convert cleanly on their own. We list these in discovery and agree what is exported for the record, rebuilt in Google tools or retired.

Yes. Mailboxes, shared mailboxes, calendars and contacts go to Gmail, Google Groups and Google Calendar. OneDrive content maps to My Drive, and SharePoint libraries map to shared drives from a written mapping plan. Office files can stay in Office format or be converted to Docs, Sheets and Slides, and we agree which before the first batch.

That is the plan. We set up Google Workspace first, run a pilot group, then migrate in batches while mail routing keeps internal and external messages flowing. The MX cutover happens last, after a final sync, and everyone gets a short quick-start guide for Gmail, Calendar and Drive.

We inventory every app that uses Microsoft as its identity provider and move each one to Google as the identity provider, or to a standalone login. Device management is planned separately: Windows and Mac devices that were managed in Intune move to Google endpoint management or another tool you choose. If you keep some Microsoft services during a transition, we plan how identity works while both are live.

Book a free scoping call. We review users, mailbox and file volume, apps, devices and anything that must be rebuilt, then send a written fixed-scope proposal. Pricing depends on those inputs, so we do not publish a single starting price for this service.
