What is Google Workspace to Microsoft 365 Migration?

Google Workspace to Microsoft 365 migration is the process of moving your organization's email, files, calendars, contacts, and collaboration tools from Google's platform to Microsoft's cloud ecosystem. This migration typically occurs when organizations want to consolidate on Microsoft 365 (formerly Office 365) for its enterprise features, Windows integration, or as part of mergers and acquisitions.

Cloudiway's migration platform enables you to move all your Google Workspace data to Microsoft 365 with full fidelity. Gmail migrates to Exchange Online, Google Drive to OneDrive, Shared Drives to SharePoint, Google Calendar to Outlook, Google Contacts to Exchange, Google Chat to Microsoft Teams, Google Groups to M365 Groups, and Google Vault to Microsoft 365 Compliance. Our delta sync technology ensures users can continue working during migration with minimal disruption.

FAQ

Google to M365 Migration FAQ

Common questions about Google Workspace to Microsoft 365 migration

How long does a Google Workspace to Microsoft 365 (Office 365) migration take?

Migration duration depends on data volume and user count. With Cloudiway's delta sync technology, you can pre-stage data over weeks while users continue working, then complete the final cutover in hours with minimal disruption.

What happens to Google Docs, Sheets, and Slides?

Google native files can be converted to Microsoft Office formats (docx, xlsx, pptx) or migrated as links that open in Google. You choose the best approach for your organization.

Are file permissions preserved during Office 365 migration?

Yes, Cloudiway automatically maps and preserves file sharing permissions. Internal shares are converted to Microsoft 365 equivalents, and external shares can be maintained or removed based on your policies.

Can we migrate Google Shared Drives to SharePoint?

Yes, Google Shared Drives can be migrated to SharePoint team sites or document libraries, with folder structure and permissions preserved.

Is there any downtime during the migration?

Cloudiway's delta sync approach minimizes downtime. Users can continue working in Google Workspace during pre-staging, with only a brief cutover window needed for the final switch.

How are Google Labels handled in Exchange?

Google Labels can be converted to Outlook folders or categories based on your preference. Multi-label emails are handled according to your configured rules.

Can we run a pilot migration first?

Yes, we recommend starting with a pilot group to validate the migration process, test configurations, and train support staff before the full rollout.

Do you support coexistence during migration?

Yes, Cloudiway supports phased migrations with coexistence features including mail routing between platforms and calendar free/busy sharing.

What about Google Chat and Google Meet data?

Google Chat conversations can be migrated to Microsoft Teams. Google Meet recordings stored in Drive are migrated with other Drive content.

Is there a free trial available?

Yes, Cloudiway offers a free trial so you can test the migration with your own data before committing to a full project.

Can I migrate from Google Workspace to Office 365?

Yes. Office 365 is the former name for Microsoft 365 — the platform is identical. Cloudiway migrates Gmail, Google Drive, Google Calendar, and other Google Workspace data to Microsoft 365/Office 365 with full fidelity.

How do you handle identity and SSO during a Google Workspace to Microsoft 365 migration?

Cloudiway recommends provisioning users in Entra ID (Azure AD) before migration, either via on-premises sync, Entra Connect Cloud Sync, or a CSV import. During cutover the MX records switch to Microsoft 365 and users authenticate against Entra ID from then on. SSO providers such as Okta or Ping can keep federating into both directories during the transition window so end users see no login disruption.
