Keyhole Software’s white paper advocates replacing legacy COBOL batch programs with Spring Batch for scalability, maintainability, and cost savings. While code conversion is faster, rewriting eliminates obsolete jobs, reduces technical debt, and streamlines processing. Spring Batch offers parallel processing, robust error handling, and easy integration with modern systems. AI tools like ChatGPT accelerate COBOL-to-Java conversion, cutting development time. Success requires skilled Spring Batch developers, domain analysts, and rigorous testing. The result: lower costs, faster batch windows, and improved agility across modern IT environments.
