GitHub Copilot and AI Agents Transform Legacy Systems
GitHub Copilot and AI agents are revolutionizing the modernization of legacy systems, particularly COBOL-based infrastructures that underpin critical global operations. With over 200 billion lines of COBOL code still in use across banking, insurance, and government sectors, the dwindling pool of skilled developers has created an urgent need for automation.
Julia Kordick of Microsoft Global Black Belt leads efforts to decode COBOL systems without human expertise. Her team employs AI-driven reverse engineering to extract business logic, map dependencies, and document archaic codebases. The three-step modernization framework begins with code preparation—stripping away decades of technical debt to reveal core functionalities.
