No rewrite · no user retraining
Same source. Same screens. Now on Linux.
This is the heart of Infinite i: you hand us your RPG and COBOL exactly as it is, and your users see the exact same screens. Nothing about the application changes — it just runs on commodity cloud infrastructure instead of Power.
// Order Entry — identical source on both platforms

if %found(CUSTMST);

✓ Compiles on IBM i (Power)
✓ Migrates to Java on Linux (x86)
No source changes on your side. No regression of decades of business rules. The same program behaviour — now running as standard Java on Linux.
The app, unchanged
Prefer to modernize the look too? Add Infinite UI to render these same screens as modern, composable web apps.
