This case study outlines the migration process undertaken by a large global transportation company to modernize its outdated programming systems. The company faced challenges due to heavy reliance on manual processes, which hindered operational efficiency and timely code updates. To address these issues, Cyient provided a customized solution using its Coddy tool, which leverages Generative AI for code migration and automated scripting. Coddy supports over 15 programming languages and automates the migration process, ensuring minimal disruption to services. The tool was instrumental in converting nearly 4,000 legacy scripts into a modern programming solution, significantly reducing manual coding time and improving system efficiency. The results included enhanced operational capabilities, increased reliability, and a notable reduction in the total cost of ownership. The case study emphasizes the effectiveness of automated tools in facilitating legacy code migration while maintaining service continuity.
