Ways to Modernize AS/400 System
Information on modernizing AS/400 systems without rewriting. Methods to create value by connecting.
Many companies have been using systems running on AS/400 for over twenty years. These systems are generally reliable and fast, but they are isolated from the outside world. Instead of rewriting, it is more sensible to build a modern layer around these systems. This approach provides concrete value at each step and allows progress without risking the system.
AS/400 systems have shaped business logic over the years. In the modernization process, it is crucial to maintain the logic of the old system while integrating with other systems through APIs. Security should not be overlooked in this process; the API layer serves as a critical point to control who can do what. This way, it is possible to modernize while enhancing the system's security.
