Legacy mainframe modernization in banking is a high-stakes operational risk, not just a technical upgrade. A custom automation workflow directly addresses this by systematically parsing undocumented CICS transactions and batch jobs, mapping business logic, and generating cloud-native services. This reduces transformation risk by preserving critical regulatory and financial logic, accelerates migration planning from months to weeks, and creates a phased, testable replacement path that protects transaction integrity and cuts long-term IT costs by 40-60%.
