Moving a company off Microsoft 365 is not a small decision. People build years of habits around Outlook and Teams.
The technical migration is only half the story. The human migration is the hard part.
Why We Considered Moving
The trigger was not one catastrophic issue. It was cumulative friction: admin overhead, workflow complexity for non-technical users, and a mismatch between tool depth and what the team actually used.
Key Facts
Migration scope
- Mail data migration.
- Calendar transfer and permission mapping.
- Contacts, aliases, forwarding rules.
- Backup and rollback planning.
Admin experience
- Google Admin generally felt simpler for day-to-day small-team management.
- Microsoft 365 Admin Center offers power, but can feel heavier for straightforward operations.
Where Google Workspace wins
- Gmail familiarity for many users.
- Simpler user lifecycle for small orgs.
- Sheets plus Apps Script is practical for lightweight automation.
Where Microsoft 365 wins
- Office file compatibility in enterprise-heavy ecosystems.
- Strong value when Teams and Office workflows are deeply embedded.
- Excel remains unmatched for many advanced spreadsheet users.
Hidden cost nobody talks about enough
Retraining non-technical staff can cost more time than the technical migration itself.
What Surprised Me
The technical tasks were manageable with planning. The bigger challenge was changing behavior patterns users had followed for years.
Folder structures, search habits, and communication norms do not migrate automatically.
Personal Take
For small teams, I lean Google Workspace.
It is usually easier to operate day to day, and the admin surface matches small-team reality better.
That said, if your business depends on advanced Excel workflows and tight Microsoft ecosystem integration, Microsoft 365 can still be the right choice.
What I Would Do Differently
- Run role-based pilot groups before full migration.
- Publish a short “new habits” onboarding guide per department.
- Budget explicit training time, not just technical migration time.
Final Recommendation
Pick the suite that matches your team behavior, not the one with the biggest enterprise feature list.
For many small teams, Google Workspace is the cleaner operational fit.
