Following the successful stabilization of the legacy framework in Phase 1, the strategic focus shifted to the total decoupling and modernization of the core architecture. This paper details the execution of a multi-year migration from ASP.NET WebForms to a modern Angular Single Page Application (SPA) and ASP.NET 6(now migrated to version 8) Microservices. Central to this transformation was a novel, database-driven state-transfer mechanism that allowed for seamless, bidirectional redirection between legacy and modern environments. By realigning 200+ legacy pages into high-performance, lazy-loaded routes and implementing a micro-service backend, we achieved a 60% improvement in page load speed and a 40% reduction in support volume while maintaining absolute business continuity for an enterprise client base.
