How long does a PowerBuilder migration take?
It depends on the size and complexity of the application. A typical mid-sized PowerBuilder application (100K-500K lines) can be converted in 8-16 weeks using VELO. The assessment phase gives you a precise timeline estimate before you commit. Larger applications with extensive DataWindow usage or complex integrations may take longer, but still significantly less time than a manual rewrite.
Do you preserve business logic?
Yes. VELO extracts and converts 100% of the business logic from your PowerBuilder application, including rules embedded in DataWindow validation expressions, PowerScript event handlers, stored procedures, and global functions. The converted code is validated through automated functional testing to confirm behavioral equivalence with the original application.
Is this a full rewrite?
No. This is an automated conversion, not a rewrite. VELO analyzes and transforms your existing code into the target framework rather than rebuilding from scratch. The result is idiomatic C#/Blazor or Java code that preserves your application's behavior and structure. You get a modern codebase without the risk, timeline, and cost of a ground-up rewrite.
What platforms are supported?
PowerBuilder applications can be converted to .NET Blazor (C# with a modern web front-end), Java with Angular, or C# with Angular. The target is deployed as a standard web application and can run on Azure, AWS, GCP, or on-premise infrastructure. The converted code uses standard frameworks and does not require any proprietary runtime.
Can we modernize incrementally?
Yes. For large PowerBuilder applications, we can convert in phases, module by module. VELO supports incremental conversion where modernized modules run alongside the legacy system during transition. This reduces risk and allows your team to validate each phase before moving to the next.
What happens post-migration?
VELO delivers an alpha-ready application with the full converted source code. There are no ongoing licensing fees for the generated code and no vendor lock-in. From there, your team handles the remaining testing, stabilization, and production hardening. If you need help with that phase, our AI Squad can take the application from alpha to a production release candidate at a fixed price. Your team owns and maintains the final codebase using standard development tools.
Is my source code secure?
Your source code is processed within a dedicated Azure environment with enterprise-grade security. Your code is never used to train AI models, is never shared across engagements, and is permanently deleted from our environment upon project completion. We provide NDAs on request and accommodate data residency requirements within Azure's regional infrastructure.
