Case Study: a leading financial services provider achieves 40% faster development with Legacyleap’s VB6 to C# modernization

Streamlining Legacy VB to C# Migration for a Leading Financial Services Provider with Gen AI

a leading financial services provider based in Salt Lake City was facing significant challenges with its monolithic VB6 system, including slow development, security vulnerabilities, and an inability to integrate with modern fintech platforms. The client partnered with Legacyleap for a Gen AI-assisted modernization to overcome these constraints and migrate to a future-ready architecture.

Legacyleap executed a phased migration to C#/.NET, eliminating hundreds of COM and ActiveX dependencies. The solution included the delivery of three standardized frameworks (DesktopCAFE, WebCAFE, BEEF) and an SOA middleware layer for integration. This resulted in 40% faster development cycles, the elimination of VB6-specific security vulnerabilities, and seamless connectivity with modern financial platforms, all while preserving regulatory compliance.
