Accelerating a Secure Enterprise Windows 11 Migration
Overview
A large enterprise health organization faced elevated operational and compliance risk after limited progress migrating more than 60,000 endpoints to Windows 11 ahead of Microsoft’s Windows 10 end‑of‑support deadline. Following 18 months of stalled delivery with prior providers, Beacon Hill Solutions Group was engaged to take full ownership of the initiative, stabilize execution and deliver a successful enterprise‑scale migration under aggressive timelines.
Our Approach
Beacon Hill Solutions Group (BHSG) applied a structured, data‑driven approach beginning with a comprehensive endpoint and application assessment to establish a validated baseline using SCCM and monitoring tools. A controlled pilot upgraded 5,000 devices to validate technical readiness, application compatibility and deployment processes.
Following pilot success, the program scaled into an enterprise rollout combining in‑place upgrades for the majority of devices with targeted rebuilds for constrained and high‑impact users. Delivery was governed through an agile operating model, weekly executive reviews, and real‑time Power BI dashboards integrated with SCCM and Azure DevOps to ensure transparency, predictable velocity and proactive risk management.
Solution Outcomes
- Migrated 100% of in‑scope endpoints to Windows 11 ahead of the internal October 15, 2025 deadline, avoiding Microsoft extended support costs
- Delivered the program under budget, reducing overall financial and operational risk
- Achieved a 99.9% device migration success rate with a 0.4% post‑deployment incident rate, demonstrating enterprise‑grade stability
- Assessed 23,000+ applications and delivered five executive dashboards providing real‑time visibility into readiness, progress, risks and exceptions
- Restored executive confidence through transparent governance, predictable delivery velocity and proactive risk management
- Positioned the organization with a modern, secure endpoint environment ready for sustained operations and future transformation
