Legacy .NET System Modernisation for a Healthcare Platform
Incrementally modernised a .NET Framework monolith serving clinical workflows for 12,000+ users without disrupting daily operations.
The Challenge
A healthcare software platform built on .NET Framework 4.5 faced mounting technical debt, security vulnerabilities, and inability to deploy features at the pace the market demanded. A full rewrite was too risky; the organisation needed a phased modernisation approach.
Our Approach
Our .NET development agency applied the strangler-fig pattern—extracting bounded contexts into .NET 8 microservices behind an API gateway, containerising services on Azure Kubernetes Service, and building comprehensive automated test suites to protect clinical workflows throughout migration.
Outcomes
- 60% of monolith functionality migrated to modern .NET 8 services
- Deployment frequency increased from quarterly to bi-weekly releases
- Zero unplanned downtime during the 18-month modernisation program
- Cloud-ready architecture supporting future Azure-native capabilities
