Platform migration
Microsoft 365 to Google Workspace migration
We plan the move so no mail is lost and your clients notice nothing: data copied while Microsoft 365 stays live, a cutover in a quiet window, then checks and a week of support.
The short answer
Most businesses can migrate from Microsoft 365 to Google Workspace using Google’s own data import tool in the Admin console, which moves Exchange Online mail, calendars and contacts, OneDrive and SharePoint files, and Teams chats at no additional tool cost. The work that decides success is around the tool: inventory, DNS and email authentication, a planned cutover, checks and training.
How the migration runs
- Inventory: users, shared mailboxes, groups, files, connected apps and "Sign in with Microsoft" logins
- Set up Google Workspace and verify your domain without touching mail
- Copy historical mail, calendars and files while Microsoft 365 stays live
- Pilot with 2 or 3 users
- Cut over in a quiet window: switch MX, update SPF, publish DKIM, keep DMARC
- Run a final pass to catch mail that arrived during the switch
- Check message counts, calendars, sharing and every connected app
- Train the team, then keep Microsoft 365 until everything is verified

Which Google tool to use
| Tool | Best for | What it moves |
|---|---|---|
| Data import (Admin console) | Most businesses | Exchange Online mail, calendar and contacts; OneDrive and SharePoint files; Teams chats |
| Data Migration Service | Small teams with simple needs | Email, calendar and contacts |
| Google Workspace Migrate | Large or complex setups | Exchange plus SharePoint and file data |
Google renames and extends these tools often. We check Google’s current admin documentation before each project.
An honest note on outages
Every cloud platform has outages, Google included. Moving reduces your dependence on one provider; a backup plan is what keeps you reachable. If outages are your only reason to move, start with the outage-ready checklist instead.
Is it right for you?
An honest check before you book a call.
A good fit if
- Your team already prefers Gmail and Google Docs
- You want simpler admin and pricing
- Outages are one of several reasons you are unhappy
- Your Microsoft 365 renewal is coming up
Probably not a fit if
- You depend on desktop Excel macros or Microsoft-only add-ins
- Outages are your only reason to move

Questions
Something else? Ask on WhatsApp or send a message. Replies within one working hour.
Will we lose any email if we migrate?
Not if it’s planned properly. Mail and files are copied while Microsoft 365 is still live, the switch happens in a quiet window and a final pass catches anything that arrived during it. Microsoft 365 stays active until everything is checked.
How long does a migration take?
It depends on users and data volume. Google’s migration planning utility estimates the timeline, and you get a written plan before anything starts.
What does Google’s data import tool cost?
Google offers data import at no additional tool cost. You pay for Google Workspace seats and, if you want us to run the project, our service.
Can Teams chats and SharePoint files be migrated?
Yes. Google’s data import now supports SharePoint Online document libraries, OneDrive files and Teams channel and chat messages, in addition to Exchange Online mail and calendars.
Does Google Workspace go down too?
Yes. Every cloud platform has outages. That is why we also set up a backup plan on the new platform.
