Google Workspace to Microsoft 365 Migration Services

MSAdvance plans and delivers Google Workspace to Microsoft 365 migrations for organizations that need to move Gmail, calendars, contacts, Google Drive and Shared Drives into Exchange Online, OneDrive and SharePoint with a defined scope, controlled migration waves and post-migration validation.

There is no single “Google to Microsoft” migration path. Email, calendars, contacts and files use different migration routes; Google Sites, Google Chat, Vault, external sharing and other components require separate treatment. The assessment determines what can move with Microsoft-native capabilities, what needs specialist tooling and what should be recreated.

Direct answer

What is a Google Workspace to Microsoft 365 migration?

It is the project of moving email, calendars, contacts, files and collaboration from Google services into Microsoft 365, typically Exchange Online, OneDrive, SharePoint, Teams and Microsoft Entra ID.

The migration is not only a data-copy exercise. Identity, domains, permissions, external sharing, coexistence, DNS, security, applications and the structural differences between Google and Microsoft also need to be addressed.

When it makes sense

Common reasons to migrate from Google Workspace to Microsoft 365

The decision should solve a business or architecture requirement, not simply reflect a preference for one productivity suite. These are common scenarios we encounter.

01

Microsoft standardization

The organization wants to standardize email, Office, Teams, OneDrive, SharePoint, identity and security around the Microsoft ecosystem.

02

M&A or consolidation

An acquired company uses Google Workspace and needs to be integrated into the group’s Microsoft 365 operating model.

03

Security and governance

The project is intended to align identity, devices, protection, classification, retention and collaboration with Entra, Intune, Defender or Purview.

04

Productivity and AI

The organization wants to restructure its workplace around Microsoft 365, Teams, SharePoint, Power Platform or Microsoft 365 Copilot.

Workload mapping

Google Workspace to Microsoft 365: what maps where

The relationship is not always one-to-one. The destination should reflect how content is actually used, the permissions model and the target collaboration architecture.

Gmail to Exchange OnlineEmail, calendars, contacts and supported rules according to the selected Microsoft migration method.
Google Drive to OneDrivePersonal files, folders, versions and supported permissions through Migration Manager.
Shared Drives to SharePoint and TeamsShared Drives are mapped into sites and libraries according to ownership, groups and information architecture.
Google Calendar to OutlookPersonal events and calendars; shared calendars and event colors have limitations in Microsoft’s native route.
Google Contacts to OutlookPersonal contacts with limits around fields and Google-specific metadata.
Google Sites to SharePointThere is no direct native Migration Manager route; Sites are typically redesigned or handled with specialist tooling where appropriate.

Why MSAdvance

The challenge is not only moving data: the target environment needs to make sense

Google Workspace and Microsoft 365 structure identity, permissions, files and collaboration differently. Our role is to identify those differences before migration and turn them into practical decisions about mapping, security, destinations and user experience.

150+Google Workspace migration projects.
25+Microsoft certifications across the team.
5+ yearsMicrosoft experience across specialist profiles.
We are not tied to one migration tool. We can combine Microsoft-native capabilities, Cloudiway, BitTitan, AvePoint and automation depending on the workload and project requirements.
What migrates and what needs review

Google Workspace and Microsoft 365 are not equivalent object by object

Microsoft’s current documentation confirms several limitations that should be understood before estimating scope or promising fidelity. This table summarizes the most important ones.

Element
Treatment
What to review
Gmail, calendar and contacts
Native route

Microsoft supports migration of email, supported rules, calendars and contacts from Google Workspace through Exchange Admin Center / PowerShell, subject to documented limitations.

Shared calendars
Limited

The standard Google Workspace migration path does not migrate shared calendars or event colors; these require separate review and treatment.

Contacts
Limited

Microsoft documents a maximum of three email addresses per contact and does not migrate certain tags, URLs or Gmail custom labels.

My Drive / Shared Drives
Migration Manager

Migration Manager can copy accessible files and folders. File versions are supported, while permission fidelity depends on correct identity mapping.

Permissions and external sharing
Review

Migration Manager can migrate mapped internal permissions, but it does not recreate external sharing links or automatically reshare content with external collaborators.

Google Forms
Supported

Migration Manager currently supports Google Forms when a suitable Forms destination is configured. Restrictions apply in some Shared Drive scenarios.

Google Sites / Maps
Not native

Microsoft states that Google Sites and Google Maps cannot be exported through Migration Manager. Sites normally require redesign or specialist tooling.

Google Chat / Spaces
Specialist tooling

This should not be assumed to be part of a standard native migration to Teams. Specialist platforms can be used where Chat history is in scope.

Google Vault
Separate strategy

Vault data is not part of Microsoft’s standard Google Workspace migration path. Retention, export and target strategy should be designed separately.

Microsoft-native capabilities

Microsoft provides dedicated routes for Google mail and Drive content

Microsoft’s native migration experience has evolved. Microsoft supports Google Workspace mail, calendar and contact migration, together with Migration Manager for My Drive and Shared Drives. Exact coverage and limitations are revalidated during assessment because Microsoft continues to expand these capabilities.

Exchange Online

Google Workspace migration

Email, supported rules, calendars and contacts through Exchange Admin Center or PowerShell, using batches or Microsoft’s automated experience.

Consolidated experience

Microsoft provides a consolidated Google Workspace migration experience for Mail and Drive, together with a simplified Gmail migration path for applicable scenarios.

Microsoft Native, Cloudiway, BitTitan and AvePoint: the tool follows the workload

Migration platforms do not cover the same objects or scenarios. The assessment determines where a native route is enough and where specialist tooling adds meaningful coverage.

Microsoft Native

Exchange + Migration Manager

Our first option when Microsoft’s native coverage fits the mail, calendar, contacts, My Drive and Shared Drive scope.

Important note about Quest On Demand Migration: Quest explicitly states that On Demand Migration does not support Google as a source environment. It is an excellent Microsoft 365 tenant-to-tenant platform, but we do not use it to migrate directly from Google Workspace to Microsoft 365.
MSAdvance methodology

The migration is prepared workload by workload and wave by wave before cutover

The objective is to reduce the number of decisions left for the final change window. Inventory, identity, target locations, permissions, tooling and user experience are validated before production data is moved.

Project control

Assessment first, tooling second

We separate email, calendars, files, identity and special components so each has a clear migration method, owner, risk profile and acceptance criteria.

1Inventory and map users, domains, Gmail, Drives and permissions.
2Design OneDrive / SharePoint destinations and the Microsoft Entra identity model.
3Run a pilot to validate performance, permissions and user experience.
4Coordinate cutover, DNS, validation and hypercare.

Identity, security and domains

The target environment needs to be ready before the business starts depending on Microsoft 365

A data migration can complete successfully and still create operational problems if users, DNS, authentication or policies are not ready. These workstreams therefore belong in the project design.

Identity and access

  • Create and map users in Microsoft Entra ID.
  • UPNs, primary addresses, aliases, groups and ownership.
  • MFA and Conditional Access when included in scope.
  • SSO, OAuth and applications that depend on Google Identity.
  • Endpoints and device management when the workplace is also being migrated.

Domain, DNS and mail flow

  • Verify domains in Microsoft 365.
  • Plan MX, SPF, DKIM and DMARC changes.
  • Temporary subdomains or routing where coexistence requires them.
  • Send/receive and calendar validation.
  • Rollback / contingency plan defined before cutover.
End-user impact

Minimizing disruption does not mean pretending that nothing changes

Moving from Google Workspace to Microsoft 365 changes tools, authentication and day-to-day habits. A good migration prepares users for that transition instead of hiding it.

What users may notice

  • New access through Outlook / Exchange Online.
  • Moving from Google Drive for desktop to OneDrive Sync.
  • New shared-content locations in SharePoint or Teams.
  • Reauthentication and MFA.
  • Mobile or profile reconfiguration where required.

How we reduce friction

  • Pilot with representative users.
  • Wave-based communication before each change.
  • Access guides and required-action instructions.
  • Out-of-hours cutover when appropriate.
  • Hypercare and post-migration functional validation.
We do not use “zero downtime” as a blanket guarantee. Expected impact is estimated according to email, Drive, DNS, coexistence, applications and the actions users may need to perform.
Applied experience

More than 1,300 users migrated from Google Workspace to Microsoft 365

In one published MSAdvance project, a European services group needed to move from Gmail and Google Drive to Microsoft 365 without carrying an outdated document structure into the target environment.

Published MSAdvance case

Email, calendars and shared documentation reorganized in controlled waves

The project combined Gmail and calendar migration with Google Drive and more than 80 Shared Drives, defining Microsoft 365 destinations and permissions before the main migration waves were executed.

These figures are not a duration or performance promise for other environments. They are evidence of hands-on Google to Microsoft 365 delivery across significant data volumes and shared structures.

Frequently asked questions

Common questions about Google Workspace to Microsoft 365 migration

What can be migrated from Google Workspace to Microsoft 365?

A typical scope includes Gmail, calendars, contacts, My Drive and Shared Drives. Microsoft provides native routes for mail, calendars, contacts and Google Drive. Other components such as Google Sites, Chat, Vault or certain sharing scenarios require specialist tooling, recreation or a separate strategy.

Can Microsoft migrate Gmail, Calendar and Contacts natively?

Yes. Microsoft documents migration of mail, supported rules, calendars and contacts from Google Workspace through Exchange Admin Center or PowerShell. There are limitations: shared calendars and event colors, for example, are not migrated in the standard route, and some contact fields are also excluded.

Can Google Drive and Shared Drives be migrated?

Yes. Migration Manager can migrate Google Personal Drive to OneDrive and Shared Drives to SharePoint. File versions are supported and permission fidelity depends on correct identity mapping.

Are external sharing links preserved?

Not automatically with Migration Manager. Microsoft states that external sharing links are not recreated and external collaborators are not automatically granted access in the target. Those permissions need to be reviewed and recreated where appropriate.

Can Google Forms be migrated?

Migration Manager currently supports Google Forms when a suitable Forms destination is configured. Microsoft documents specific restrictions, including some Shared Drive scenarios.

Does Google Sites migrate to SharePoint automatically?

Not through Migration Manager. Microsoft states that Google Sites and Google Maps are not exported with that tool. Sites can be redesigned in SharePoint or handled with a specialist platform that supports an appropriate migration path.

Can Google Chat be migrated to Microsoft Teams?

It should not be assumed to be part of Microsoft’s standard native migration path. Platforms such as Cloudiway and AvePoint publish capabilities for migrating Google Chat / Spaces into Microsoft Teams. If chat history is in scope, we review volume, conversation type, target behavior and fidelity requirements.

What happens to Google Vault?

Vault is not part of Microsoft’s standard native Google Workspace migration path. If retained or archived data must be preserved, a separate export, retention or migration strategy is required using tooling that supports the scenario. Future retention in Microsoft Purview is designed separately.

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

It depends on user count, Gmail and Drive volume, Shared Drives, permissions, API limits, coexistence and special workloads. The assessment and a pilot make it possible to estimate realistic timings by wave and define the cutover window.

Can the migration be completed with no user impact?

The objective is to minimize disruption, but we do not promise universal “zero downtime.” Outlook, OneDrive, Teams, mobile devices, MFA and DNS changes may require user actions or a controlled change window. Expected impact is documented during the design phase.

Which migration tools does MSAdvance use?

It depends on the workload. We can use Exchange Admin Center, Migration Manager and other Microsoft capabilities, together with Cloudiway, BitTitan or AvePoint where they provide additional coverage. Quest On Demand Migration is not used with Google as the source because Quest documents that ODM does not support Google Workspace as a source environment.

What information do you need to provide a quote?

User and domain counts, mailbox count and size, My Drive volume, Shared Drive count and size, permissions, Sites, Chat, Vault, identity model and target date. With that information we can prepare an initial estimate and determine whether a detailed assessment is required.
