How to Migrate from Google Workspace to Microsoft 365

Migrating from Google Workspace to Microsoft 365 is a major undertaking — but with the right plan, it can be completed with zero email downtime and minimal disruption to your team.

Migrating from Google Workspace to Microsoft 365 is one of the most requested IT projects for growing businesses — particularly those entering regulated industries, winning enterprise contracts that require Microsoft platforms, or finding that their team spends more time in Word, Excel, and PowerPoint than Google Docs.

When to Migrate from Google Workspace to Microsoft 365

The decision to migrate is usually driven by enterprise contract requirements, compliance requirements (HIPAA, CMMC, financial services), Windows ecosystem alignment, or feature requirements for mature Teams and SharePoint integration.

Migration Timeline for a 50-User Business

A well-executed G Suite to M365 migration for a 50-person company typically takes 4–8 weeks: weeks 1-2 for assessment and coexistence setup, weeks 3-4 for data migration, weeks 5-6 for user training and testing, and weeks 7-8 for cutover and parallel running.

Common Migration Mistakes to Avoid

• Skipping user training — the #1 reason migrations fail. Google Docs to Word is not intuitive.
• Not migrating shared drives properly — Google Shared Drives map to SharePoint document libraries, not OneDrive
• Forgetting third-party integrations — audit every Google app connected to your workspace
• Rushing the cutover — always run in parallel for at least two weeks before fully cutting over
