Windows 11 Migration: Building Secure, Scalable Foundations for Reliance and GDI

With Windows 10 support ending on October 14, 2025, organizations are under pressure to modernize. After that deadline, Microsoft will no longer provide free security updates or technical support. Unpatched systems will be exposed and unsupported.

‍

Reliance and GDI both needed to migrate to Windows 11, but each had unique priorities.

‍

Reliance, a national utility and infrastructure services provider, was working across 15 different hardware models with no standardized image.

‍

Endpoint management was fragmented. App deployments were inconsistent and slow. They needed a consistent, secure deployment strategy built for scale.

‍

GDI, a national facility services organization, needed to validate its readiness before committing to an enterprise rollout.

‍

Their team required a low-disruption pilot to test compatibility, confirm licensing, and define servicing policies with minimal risk.

BITSUMMIT delivered a dual-track Windows 11 migration strategy. One track focused on large-scale deployment. The other focused on low-risk validation.

‍

Reliance: Foundation for Scalable Deployment

• Compatibility testing across 15 hardware models
• Custom Windows 11 image with corporate branding and up-to-date security patches
• Packaged deployment of six key applications: FortiClient VPN, Microsoft Office, Chrome, Rise, Zoho Assist, and endpoint protection
• Pre-tested image handed off for enterprise deployment using SCCM and BigFix

GDI: Proving Readiness, Reducing Risk

• Full Microsoft 365 and OS readiness assessment
• 25-device pilot deployment via Intune, executed in two controlled phases
• Delivery of a tailored upgrade plan, servicing policy recommendations, and a detailed readiness report

Cross-Client Playbook Highlights

• Role-based access and license validation maintained from start to finish
• Delivered upgrade summaries, validation reports, and servicing documentation
• Transparent billing model with milestone checkpoints and hourly tracking

‍

These were not quick tech fixes. They were foundational upgrades.

‍

Reliance now operates with a fully standardized, secure Windows 11 image. It is fast to deploy, production-ready, and scalable across the enterprise. Their IT operations have moved from fragmented to fully streamlined.

‍

GDI exits the proof-of-concept phase with clarity, confidence, and a roadmap for full rollout. Their leadership team now has real-world validation, strategic guidance, and a secure path forward.

‍

With BITSUMMIT’s tailored migration approach, both organizations transitioned from reactive IT environments to future-ready infrastructure. Each moved forward on time and on their terms.
