Direct synchronous database locks

PowerBuilder's direct database connections lock your architecture to on-premise, blocking cloud adoption and headless platform transitions.

PowerScript dynamic execution strings

Modify/Describe calls in PowerScript create runtime fragility and make migration risky without deep platform expertise.

Local Windows print server dependencies

Relying on local print servers ties your application to desktop environments, frustrating users and limiting modern deployment options.

PowerBuilder → React migration — your questions answered

How long does it take to migrate PowerBuilder to React?+

Typical projects run 6-11 months with 3-6 senior consultants. We use a fixed-scope model so you know the timeline upfront.

What is the typical budget for a PowerBuilder to React migration?+

Projects range from $130,000 to $1,100,000 depending on complexity. We provide a detailed assessment before setting scope and price.

How do you handle PowerScript dynamic execution (Modify/Describe) during conversion?+

Our engineers analyze all Modify/Describe strings and replace them with React state management. We've done this for hundreds of DataWindow controls.

Can we keep our legacy system running while you build the React frontend?+

Yes. Your PowerBuilder app stays under vendor support as long as your contract is active. If it lapses, our third-party support covers most operational issues while you migrate.
