Transform IBM i RPG and COBOL into cloud-native microservices, de-risked by AI.
AS/400 systems are the backbone of many banks, insurers and logistics firms, often with no current documentation. Paradym Next reads the RPG, COBOL and CL, recovers the business rules and rebuilds them as cloud-native services with React or Vue 3 front ends: in months, not a multi-year rewrite.
Decades of business logic sit on a platform fewer people can work on.
IBM i is reliable, but the applications on it were built for green screens and batch jobs. Connecting them to digital channels, data platforms and partners gets harder every year.
Retiring RPG talent
The developers who wrote and maintain the code are retiring, and few new engineers learn RPG.
Green-screen interfaces
5250 screens and batch processes slow staff down and are hard to extend to web or mobile.
Integration bottlenecks
Exposing data and transactions to modern systems needs custom middleware for each connection.
Platform cost
Hardware, licences and specialist support keep running costs high.
Interest calculations, policy rules and shipping logic are buried in RPG indicators, subfiles and CL job streams that have changed for decades without documentation. Recovering them is what makes a safe move off the platform possible.
How our AI-powered modernisation engine works.
Four stages take your IBM i application from undocumented code to cloud-native microservices with React or Vue 3 front ends on AWS or Azure. AI agents do the reading, mapping, writing and testing. Your engineers approve every stage.
Automated discovery and code parsing
Next parses your RPG and COBOL programs, CL programs, display and printer files, and DB2 for i tables and extracts the business rules, data flows and integrations inside them. Every rule is traced to the code it came from, so nothing drifts in translation.
AI-assisted architecture blueprint
Agents map each module to clean target patterns: domain microservices, event-driven integration, REST APIs, React, Vue 3 or Nuxt front ends in place of green screens, and managed cloud databases. Your architects review and approve the blueprint before any code is written.
Automated refactoring
From the approved blueprint, Next generates production-ready code for cloud-native microservices with React or Vue 3 front ends on AWS or Azure. It consolidates duplicated logic and removes dead code, and your engineers review every change.
AI-driven regression testing and validation
Generated test suites run the old and new systems on the same inputs, validating 99% functional equivalence before deployment. Any difference goes to your team to resolve.
What AI acceleration changes.
Compared with a standard manual migration of your IBM i application.
less development effort than a standard manual migration.
faster upgrade and migration cycles.
lower operational and cloud infrastructure overhead.
AI does the heavy lifting. Your engineers make the decisions.
For a CTO or CIO, the risk in a rewrite is not speed but correctness. Human review is built into every stage, so AI output never reaches production unchecked.
Traced to source
Every extracted rule and generated module links back to the IBM i code it came from, so reviewers can check it line by line.
Human approval gates
Discovery, blueprint, code and release each need sign-off from your people. Nothing moves forward on AI output alone.
Equivalence testing
Old and new systems run the same test cases side by side, validated to 99% functional equivalence before deployment.
Governed AI
You choose which models are used and where they run, and every agent action is recorded for audit.
