You have been asked to design a zero-touch deployment strategy for a Fortune 500 company migrating 10,000 employees from a mixed Windows and legacy Mac environment to managed macOS devices. The company wants devices shipped directly to employees and provisioned through Apple Business Manager, Automated Device Enrollment, and a mobile device management platform with minimal IT hands-on support. The migration matters because leadership wants to reduce onboarding time, improve security posture, and standardize endpoint management before the next fiscal year. The tricky part is that employees span multiple regions, several business-critical apps still rely on legacy packaging and VPN profiles, the security team requires FileVault, compliance controls, and conditional access on day one, and the CIO has committed to an aggressive rollout window while business leaders are worried about downtime for sales and engineering teams.
| Detail | Value |
|---|---|
| Users to migrate | 10,000 |
| Rollout window | 6 months |
| IT endpoint engineers | 6 |
| Help desk staff | 18 |
| Regions | 4 |
| Critical applications | 25 |
| New-hire and refresh devices | MacBook Air and MacBook Pro |
| Security requirements | FileVault, SSO, VPN, compliance enforcement |
| Deployment model | Zero-touch via Apple Business Manager + Automated Device Enrollment |
Walk me through how you would design and execute a zero-touch deployment strategy for this migration, including how you would phase the rollout, align stakeholders, define success, and handle risk if enrollment, app delivery, or user readiness does not go as planned.
