Google Workspace to Microsoft 365 Migration
CloudTechForce migrates businesses from Google Workspace to Microsoft 365 in two to four weeks: Gmail to Exchange Online, Google Drive and Shared Drives to OneDrive and SharePoint, Calendar and Contacts to Outlook, with sharing permissions mapped and a weekend cutover so nobody loses a message. Pricing is per mailbox and per terabyte, and free for 10–20 user teams that start a quarterly managed IT plan.

Why businesses move from Google Workspace to Microsoft 365
- The rest of the business already lives in Excel, Word and Teams, or a client or parent company requires it.
- Compliance needs (HIPAA, CMMC, SOC 2) are easier to evidence with Microsoft Purview, Intune and Defender in one tenant.
- Windows device management (Intune, Autopilot) and identity (Entra ID) simplify security for a Windows-heavy office.
- Licensing consolidation: Microsoft 365 Business Premium bundles Office apps, device management and security that Google sells as separate add-ons.

What we migrate
| Google Workspace | Microsoft 365 destination | Notes |
|---|---|---|
| Gmail (mail, labels, filters where possible) | Exchange Online mailboxes | Labels become folders; nested labels preserved |
| Google Calendar (events, recurring meetings, resources) | Outlook calendars | Attendee responses re-validated; room resources recreated |
| Google Contacts | Outlook contacts | Groups mapped to contact lists |
| My Drive | OneDrive for Business | Ownership preserved; Google-native files converted to Office formats |
| Shared Drives | SharePoint document libraries | One site per shared drive by default, or a structure designed with you |
| Google Groups | Microsoft 365 groups and distribution lists | Membership and delivery settings recreated |
| Google Meet and Chat history | Teams | Meet recordings moved; Chat history export only |
| Google Sites, Forms, Apps Script | SharePoint, Microsoft Forms, Power Automate | Rebuilt, not migrated; scoped separately |
How the migration runs
- Week 1, discovery. Export of users, groups, shared drives, sizes and external sharing; DNS and domain review; licence plan; MFA and Conditional Access baseline agreed; staff communication plan.
- Week 2, tenant build and pre-staging. Users created or synced, mailboxes provisioned, historical mail and files copied in the background using Microsoft's [Google Workspace migration tooling](https://learn.microsoft.
- Cutover weekend. MX and autodiscover records switched, final delta sync of mail and files, Outlook and mobile profiles configured, sharing permissions applied on SharePoint, a "what changed" page sent to every user.
- Weeks 3–4, support and clean-up. Priority help desk for migration issues, permission report reviewed with you, Google Workspace reduced to a read-only archive for 30 days then decommissioned, Microsoft 365 backup switched on.

The things that go wrong when this is done badly
- Calendar invitations that show as tentative for everyone because acceptances were not migrated.
- Shared Drive files that arrive with no permissions, so the whole company can suddenly see HR.
- Google-native Docs migrated as links to a Google account that is about to be deleted.
- Aliases and group addresses that silently stop receiving mail after cutover.
- MFA "to be done later", which becomes never.
We check each of these against a written test plan before we call the migration complete.

FAQ
Frequently asked questions
How long does a Google Workspace to Microsoft 365 migration take?
Two to four weeks for 10–100 users: one week of discovery and tenant build, one to two weeks of background pre-staging, a weekend cutover and two weeks of support.
Will our email go down during cutover?
No. Historical mail is copied while Gmail stays live; on cutover weekend we switch DNS and sync the last few hours of mail. Users open Outlook on Monday with everything in place.
What happens to Google Docs, Sheets and Slides?
They are converted to Word, Excel and PowerPoint formats during the Drive migration. Complex Sheets with Apps Script or Google-only functions are flagged in the discovery report so you can decide how to handle them.
Can we keep Google Workspace for some users?
Yes, in a coexistence arrangement, but it doubles licensing and complicates mail routing. We usually recommend a single cutover with a 30-day read-only Google archive.
How much does it cost to migrate Google Workspace to Microsoft 365?
Free for 10–20 user businesses that start a quarterly managed IT plan.
Do you provide training?
Yes: a one-page 'what changed' guide for every user, a 45-minute live session on cutover day, and two weeks of priority help desk.
