Overview
Moved a distributed workforce from Google Workspace to Microsoft 365 with secure endpoints, adoption playbooks, identity controls, and governed cutover.
When COVID forced teams remote overnight, we had already staged the Microsoft 365 migration playbooks. Each wave included change champions, training kits, and telemetry that tracked mailbox cutovers, licensing status, and device compliance. Intune policies enforced encryption and remote wipe, while conditional access protected the perimeter.
Executives got weekly briefings: adoption metrics, incident trends, and remediation status. Frontline staff had self-service guidance and Teams-based office hours. The program kept the business running while we retired Google Workspace, modernized laptops, and put governance in place for the long haul.

What shipped
Developed a phased migration plan covering 500+ mailboxes with zero data loss.
Rolled out Intune policies within the first 30 days to secure distributed endpoints.
Built executive dashboards showing adoption, incident response times, and support ticket trends.
Change champions, training kits, and office hours ran in every cutover wave.
Journey
**Stage the playbooks:** Prepared wave plans, licensing, and telemetry before COVID forced remote work overnight.
**Secure the perimeter:** Intune encryption, remote wipe, and conditional access went live with the first waves.
**Cut over with champions:** Each wave included training kits, Teams office hours, and adoption dashboards.
**Brief executives weekly:** Adoption, incidents, and remediation status replaced rumor with a single narrative.
Lessons
Playbooks beat heroics
Migration under crisis only works if the operating plan exists before the pressure arrives.
Telemetry calms sponsors
Weekly adoption and incident briefings keep leadership from managing by anecdote.
Security travels with the laptop
Endpoint and identity controls have to ship in the same wave as the mailbox cutover.
Reflection
The migration succeeded because change enablement and endpoint governance launched with the platform—not as a cleanup project afterward.
