Mainframe applications serve as the backbone of many critical systems for modern enterprises. While they are integral, the need for modernization becomes inevitable to keep up with the demands of a rapidly evolving digital landscape.

One of the major hindrances to this modernization is the scarcity of expertise in mainframe technologies. As seasoned mainframe professionals retire, attracting new talent is a challenge. Many aspiring developers today prefer working with newer technologies and languages, often overlooking the potential of COBOL, the main language of mainframe applications.

Yet, COBOL, originally created long before modern programming paradigms, is not as complex as it may seem. The challenge lies in the accumulative modifications and intricacies made by multiple developers over the years. This complexity makes traditional approaches to application development on mainframes daunting and leads many organizations to prematurely seek alternatives off the mainframe.

Breaking away from these limitations, there is a novel approach that leverages generative AI to facilitate the modernization of mainframe applications. IBM is at the forefront with their AI-powered solution, IBM watsonx™ Code Assistant for Z, designed to streamline the transition from COBOL to Java, making the process more efficient and accessible.

Here are the three key steps facilitated by the IBM watsonx™ Code Assistant for Z:

1. Discovery: The solution conducts an in-depth inventory of all mainframe programs, mapping out their architectural flow diagrams to identify dependencies and potential roadblocks within the code base.
2. Refactoring: It breaks down the monolithic COBOL code into modular business service components, enhancing the overall agility and malleability of the applications.
3. Transformation: Leveraging generative AI tuned on enterprise COBOL-to-Java conversion, the solution translates COBOL program components into Java classes, facilitating a parallel, agile development approach.

These advancements mark a substantial acceleration in the modernization of mainframe applications, enabling organizations to enhance their agility and adaptability in a cost-effective manner.
