Case Study: a bulk fuel distribution software company achieves 60% lower modernization costs with Legacyleap

Gen AI-Driven VB6 Modernization for a Fuel Distribution Software Company via Legacyleap

A UK-based bulk fuel distribution software company was facing significant challenges with its 30-year-old VB6 system. The fat-client architecture created scalability and maintenance bottlenecks, and the company lacked the budget for a traditional multi-million-pound rewrite. They needed to modernize without disrupting their 500-600 active users or sacrificing the system's deep configurability. They engaged Legacyleap to leverage its Gen AI-powered modernization framework for a solution.

Legacyleap executed a phased, AI-driven modernization strategy. Using Gen AI automation, they handled 50-70% of the code transformation, significantly reducing manual effort. They employed AI-driven testing to validate the complex system and used a hybrid deployment model to migrate users incrementally without disruption. The results for Legacyleap's client were a 60% lower cost than traditional approaches, an 80% reduction in manual effort, and a 40% faster feature rollout, successfully moving all users to a new cloud-ready web platform.
