Case Study: Modernizing Connections: A Seamless Migration to .NET 8 and Angular 18 from ASP .NET and VB.NET
Transforming Legacy Systems for a Future-Ready Healthcare Platform
In an era where technology evolves rapidly, businesses relying on outdated systems risk inefficiency, security vulnerabilities, and operational bottlenecks. This case study explores how a global healthcare services company successfully migrated its 15-year-old legacy application—built on ASP.NET and VB.NET—to a cutting-edge .NET 8 and Angular 18 ecosystem.
The Challenge
The legacy application, a critical tool for patient support and insurance claims management, faced mounting challenges:
-
Outdated Architecture: Limited scalability and security vulnerabilities.
-
Complex Business Logic: Over 50,000 lines of legacy code required meticulous refactoring.
-
Stringent Security Needs: Compliance with modern standards like TLS 1.3 was non-negotiable.
The Solution
The migration project embraced a microservices architecture, modularizing the application into scalable components:
-
Backend: Modernized with C# and .NET 8 for enhanced performance and security.
-
Frontend: Rebuilt using Angular 18 and Bootstrap for a responsive, user-friendly interface.
-
Security & Performance: Addressed vulnerabilities and optimized load management.
Key Outcomes
-
Future-Proof Scalability: The new architecture supports seamless growth.
-
Enhanced User Experience: Intuitive interfaces for call center agents.
-
Robust Security: Compliance with industry standards ensured.
