Google Workspace Migration

Executive Summary​

Google Workspace migration moves mail, calendar, contacts, Drive content and collaboration workflows into Microsoft 365.

The program should be planned as identity, data, collaboration and change management workstreams. A mail-only view misses user behavior, file ownership and coexistence complexity.

한국어 요약​

Google Workspace Migration은 Gmail만 Exchange Online으로 옮기는 작업이 아닙니다.

Identity, domain, alias, group, calendar, Drive ownership, shared drive, external collaborator, user adoption을 함께 설계해야 Microsoft 365 전환 리스크를 줄일 수 있습니다.

Business Scenario​

  • Consolidate collaboration platforms
  • Move from Gmail and Drive to Exchange Online, Teams, SharePoint and OneDrive
  • Standardize identity and security controls
  • Prepare Microsoft 365 Copilot adoption
  • Reduce duplicate licensing and administration

04User adoptionSupport behavior change, training, migration waves and post-cutover hypercare.

Implementation​

  1. Assess users, aliases, groups, mail routing and Drive ownership.
  2. Design identity and coexistence model.
  3. Prepare Exchange Online, SharePoint, OneDrive and Teams.
  4. Run pilot migration for representative users.
  5. Plan communication, training and support.
  6. Execute migration waves.
  7. Validate mail flow, calendars, permissions and file access.

Security​

  • Review third-party app access before migration.
  • Map Google groups to Microsoft 365 groups carefully.
  • Validate sharing links and external collaborators.
  • Apply Conditional Access and device compliance after migration readiness.

Decision Checklist​

DecisionRecommended Question
CoexistenceIs coexistence required or will users cut over by wave?
Identity mappingHow are users, aliases, groups and domains mapped?
Drive ownershipWho owns shared drives and orphaned content?
CalendarWhich room, resource and shared calendar scenarios are in scope?
AdoptionHow will users learn Outlook, Teams, SharePoint and OneDrive workflows?

Lessons Learned​

Drive ownership and shared drive structure often create more complexity than mailbox migration. Early inventory and business owner validation reduce cutover surprises.
