TCS MasterCraft uses GenAI to cut modernization costs by 70% and doubles delivery speed for legacy system upgrades.
TCS has unveiled a GenAI-powered upgrade to its MasterCraft platform, aimed at tackling one of the toughest tech hurdles: legacy system modernization. This enhanced version uses GenAI and Agentic AI to automate complex modernization tasks that usually require deep manual effort. It quickly mines business logic, translates outdated code, and ensures cleaner, future-ready systems. The result? TCS GenAI save over 70% in costs and complete projects twice as fast as with older methods.
Modernization has always been risky and costly—often leading to new systems that are just as outdated as the old ones. TCS is changing that. With GenAI, MasterCraft analyzes legacy codebases, extracts core logic, and converts them into sustainable, cloud-friendly architectures. Agentic AI adds another layer—tailoring intelligent agents to guide decisions and adapt to unique system requirements. The automation also maintains a human-in-the-loop model, letting teams step in where needed.
Real-world success shows the scale. A top North American bank used this platform to modernize its mainframe systems. Results included 3X faster project delivery and 90% effort savings in documentation. Another project involved migrating 50 million lines of COBOL to Java for a global finance firm—an impossible task made achievable with GenAI. Each effort builds a re-usable knowledge base for future system upgrades.
TCS has already delivered over 580 AI-centered modernization projects this fiscal year alone. With over 150 Agentic AI use cases now active, MasterCraft continues to evolve into a smart, adaptive system that supports digital transformation at scale. For industries bogged down by aging infrastructure, GenAI isn’t just a tool—it’s becoming the backbone of long-term tech resilience.
