Modernising a legacy AS/400 (IBM i) system without rewriting it

Many companies still depend on aging AS/40s, now known as IBM i, for critical business operations like production and invoicing, often running these systems for over two decades. Rather than scrapping and rebuilding these systems, which is usually more costly and risky, it's often more effective to modernize them through incremental updates and enhancements. This approach not only preserves existing functionality but also integrates new technologies, ensuring the system remains robust and efficient. This strategy is essential as businesses seek to maintain operational continuity while evolving their tech infrastructure.
