Super AI/Use Cases/COBOL & Mainframe Modernisation
Legacy Technology

Forty years of COBOL. Gone in weeks.

Your AS/400 estate costs $2M+ a year to maintain. The engineers who understand it are retiring. Modern teams won't touch it. Lazarus converts the entire estate — COBOL, RPG, CL, DDS screens — to Java 21 + Spring Boot, with auto-generated tests, a database migrator, and a parallel-run engine that proves correctness before you decommission the iron.

03 / The problem

Why this is hard without agents.

Mainframe estates cost millions annually. Vendor lock-in. Talent shortage. No documentation. Big-bang rewrites fail. Traditional migration engagements take years.

04 / How agents do it

The agent workflow, step by step.

01Analyzer agents map the full COBOL/RPG estate — complexity, dependencies, risk
02Converter agents transpile paragraph-by-paragraph to Java 21 + Spring Boot
03Test agents generate JUnit 5 tests from WORKING-STORAGE values
04DB agents migrate DB2/400 physical files to PostgreSQL with Flyway scripts
05Parallel-run agents mirror traffic to both systems and compare outputs
06Deploy agents SSH into the target server and handle the full deployment
05 / The Super AI approach

Why Super AI for this.

Lazarus is a credit-based SaaS, not a fixed-engagement. You start with a single program, prove the approach, expand. Atlas unifies data across old and new. Chronos provides audit trails for regulators.
