Programme context
Network Rail scaled governed enterprise application development on Microsoft Power Platform, supporting approximately 2,500 makers and replacing named manual, paper-based and prior low-code processes.
Why this matters: This record identifies a named Irish or UK organisation, a bounded predecessor state, a destination platform, an affected workload and a source-stated operational stage.
Migration timeline
| Date or stage | Milestone | What changed | Evidence status |
|---|---|---|---|
| Predecessor state | Manual and prior low-code processes | Safety and operational workflows included paper-based and inflexible systems. | Source stated |
| Scale phase | Governed maker estate | Power Platform expanded to approximately 2,500 makers and thousands of apps and flows. | Source stated |
| 28 April 2026 | Dated publication | Microsoft published the operational scaled case. | Source stated |
Workload migration matrix
| Workload | Predecessor | Destination | Status by 27 Jul 2026 |
|---|---|---|---|
| enterprise application development, workflow automation and safety reporting | manual, paper-based and inflexible processes plus a prior low-code platform | Microsoft Power Platform with Managed Environments and Copilot Studio | Operational and scaled |
Implementation and architecture
- Power Apps and Power Automate support application and workflow delivery.
- Managed Environments strengthen governance.
- Copilot Studio is part of the current platform direction.
Known unknowns and contradictions
- The exact count of retired prior applications is not stated.
- No single estate-wide production cutover date is stated.
- The complete boundary of the earlier low-code platform is not identified.
No missing fact is inferred to broaden the source-supported platform-change claim.
PlatformTrace analysis
The dated source supports operational scale and named process replacements. It does not identify a single estate-wide cutover or prove retirement of every prior application and platform.
Performance, cost, uptime and operational outcomes remain attributed source claims unless independently stated otherwise.
