Migrating from COBOL with AI: A Moonshot Demo

Julia Kordick

Still terrified of touching massive legacy mainframes? Discover how a fault-tolerant, multi-agent AI framework systematically reverse-engineers and translates complex COBOL programs into modern Java.

#1 about 2 min

Multi-agent AI for migrating legacy COBOL to Java

An open-source project uses multi-agent AI to help financial institutions modernize legacy mainframe codebases.

#2 about 1 min

Accessing the repository and collaborating on COBOL problems

Developers can access the project resources on GitHub and collaborate on solving complex legacy codebase problems.

#3 about 2 min

Setting up the environment and executing the migration tool

The required setup involves configuring an AI endpoint and using a provided dev container for seamless execution.

#4 about 1 min

Understanding the multi-agent flow and COBOL code analysis

The initial analyzer agent performs reverse engineering and preparation steps on legacy source files to begin migration.

#5 about 2 min

Parsing dependencies and complex COBOL call chains

The dependency analyzer agent maps unconditional jumps and intricate call chains between legacy files.

#6 about 1 min

Orchestrating AI agents with the Semantic Kernel framework

The project utilizes Semantic Kernel in C# instead of Autogen to manage complex agent logs and orchestration effectively.

#7 about 1 min

Storing intermediate results for fault-tolerant AI migrations

The system stores intermediate state in markdown files to gracefully handle errors during long-running code conversions.

#8 about 1 min

Extending the framework beyond COBOL to Java migrations

The flexible framework allows developers to target different source and destination languages by adjusting agent personas.

#9 about 2 min

Reviewing generated Java code and migration documentation

An inspection of the output directory reveals the newly generated Java code, comprehensive migration reports, and architecture diagrams.
