Case Study: a multinational semiconductor manufacturing company accelerates ColdFusion-to-.NET modernization with Legacyleap

How Gen AI Accelerated a Phased ColdFusion to .NET Modernization for a Multinational Semiconductor Manufacturer

A multinational semiconductor manufacturer faced the challenge of modernizing its undocumented ColdFusion applications to .NET through a mandatory, complex three-stage process. The project was further complicated by strict AI governance policies that blocked the use of major LLMs and required a guarantee that no sensitive data would leave the company's firewall. Legacyleap was engaged to address this challenge.

Legacyleap deployed an on-premise AI middleware layer using AWS Bedrock to execute the multi-phase migration without breaching the client's firewall. The solution auto-generated documentation and test cases from the legacy code, accelerating the transformation. As a result, Legacyleap delivered the modernization 60% faster than manual estimates, reduced costs by 40-50%, and achieved full business logic preservation with zero data exfiltration incidents.
