    IBM's Assembler to Java Modernization on Legacy Systems leveraging GenAI

     Info

    Overview

    Organizations reliant on legacy systems often face challenges such as skill shortages, outdated documentation, and complex application environments.
    For example:

    1. Skills Shortage: In many cases, client employees and contractors maintaining the legacy code are retiring. Refilling these positions can be difficult and expensive due to lack of skilled professionals in the market with required expertise (e.g. COBOL and Assembler)
    2. Tribal Knowledge: Lack of up-to-date documentation and limited availability of tools capable of effectively deciphering the (complex) logic, rules, and requirements embedded in the application code, which leads to over reliance on tribal knowledge.
    3. Complex Application Environments: Legacy systems are typically batch-based with hundreds of monolithic applications. The desired target state is often real-time, event-driven on the cloud and this combination results in a non-trivial modernization path.

    IBM Consulting addresses these issues with a proven, AI-driven solution leveraging AWS products and services (including Amazon Bedrock, Code Llama) that transforms mainframe legacy code like Assembler into modern, cloud-ready Java architectures. Our service delivers rapid results, reducing time-to-value and eliminating manual bottlenecks. By automating rule extraction and code translation, organizations gain actionable insights into their legacy systems, such as identifying obsolete dependencies and uncovering hidden optimization opportunities, enabling faster modernization while minimizing risks. IBM’s approach promotes compliance with industry standards and positions organizations to leverage cutting-edge cloud technologies for sustainable growth.

    Outcomes have shown a 60-70% improvement in operational efficiency, streamlined workflows that reduce project complexity, and up to a 40% decrease in dependency on outdated technical expertise. With IBM Consulting and AWS, clients transition to modular, real-time, event-driven architectures tailored to their business needs.
