Your PowerBuilder application’s business logic is an asset. The interface is a cost.
Most organizations treat them the other way around.
The correct framework is three words:
Preserve ā every DataWindow definition, computed column, validation rule. Treat it as a corporate asset.
Rehost ā .NET DataStore brings DataWindow semantics into .NET without rewriting them. The logic executes identically. The container changes.
Replace ā comprehensively. React or Angular for web. React Native or Flutter for mobile. Rebuilt from the ground up.
The logic is the asset. The presentation is the liability. Treat them accordingly.
What’s the most important business logic in your application you’d be terrified to lose?
