No rewrite · no retraining
Same source. Same screens. Now on Linux.
This is the heart of Infinite i: your unchanged RPG and COBOL source compiles on IBM i and on Linux, 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

✓ Compiles on IBM i (Power)
✓ Compiles on Linux (x86)
No source changes. No regression of decades of business rules. The same program object behavior, recompiled to run natively on Linux.
The app, unchanged
Prefer to modernize the look too? Add Infinite Cloud to render these same screens as graphical web interfaces.
