A suite of advanced tools that extract, document and modernise decades of hidden business logic from Mainframe COBOL, JCL and DB2 — turning undocumented code into actionable specifications.
Each product targets a specific bottleneck in legacy modernisation — from understanding what exists to building what comes next.
Zip your COBOL programs, JCL jobs, BMS maps, Copybooks and DB2 DDL files. Upload via the web UI or the REST API. No code changes, no agents to install.
The platform parses each file type, maps call dependencies, and analyses each program automatically. Business rules, SQL statements, field mappings, error handling — all extracted without manual effort.
Every COBOL module receives a risk score (0–100) based on complexity, coupling, size and DB access patterns. A full dependency graph is rendered as PNG and interactive SVG.
Receive a multi-page PDF with 10-section business specifications per module — ready for stakeholder review, handover to Java teams, or compliance audit.
Every ilumeny product is designed to meet the compliance requirements of German banks, insurance companies and government organisations.
