Windows 10 to 11 Device Migration
A multi-site client engaged us to manage a large-scale operating system upgrade from Windows 10 to Windows 11 across their environment. The project involved upgrading 157 PCs across two locations while ensuring business continuity and meeting an external deadline of October 2025.

Case Breakdown
A detailed look at the challenge, our approach, and the measurable outcome.
The Challenge
All systems were running Windows 10, and the client needed to complete the upgrade before the October 2025 deadline. With 157 active endpoints, performing a mass upgrade without proper testing could have caused user disruption, compatibility issues, and productivity loss. One location housed approximately 40 PCs, while the second site contained the remaining systems, requiring a phased and controlled rollout.
The Solution
We designed a phased upgrade strategy focused on testing, stability, and minimal user impact:
- Identified non-production and low-use PCs at the smaller site to serve as a testing group
- Performed overnight test upgrades to identify compatibility issues and configuration changes
- Documented and resolved minor issues discovered during testing
- Implemented a weekly phased rollout, upgrading systems in controlled batches
- Scheduled overnight upgrades to avoid business-hour disruptions
- Maintained on-standby support after each upgrade window to assist users with Windows 11 interface and settings changes
The Result
All 157 PCs across both locations were successfully upgraded to Windows 11 ahead of the October 2025 deadline. The phased rollout minimized downtime, reduced user disruption, and ensured system stability. Users received immediate support for post-upgrade configuration changes, resulting in a smooth transition from Windows 10 to Windows 11 with no significant operational impact.
