We use AI to support you end to end —
from migration and testing to operations.
Oracle Forms, PowerBuilder, VB6 — move the business systems you run today onto .NET without rebuilding them. A conversion tool refined with AI and our own compatibility libraries deliver migration quality that doesn’t vary.
What we do
We move your systems onto maintainable technology while keeping the current screens, operations and database.
AI-Driven Modernization
AI is the tool that builds the converter, not the converter itself. The same input always gives the same output, and your source code is never uploaded to an AI.
Learn more →Oracle Forms Migration
Screens (FMB), triggers, PLL and reports (RDF / SQR) to Windows Forms and C#. Free yourself from WebLogic and the Java runtime — with a Web (Blazor) option.

PowerBuilder Migration
PowerScript and DataWindow to .NET. Our support library absorbs DataWindow and OCX compatibility, and we migrate one business domain at a time.
Learn more →VB6 & Classic ASP Migration
VB6 to C# / Windows Forms (.NET 10) and Classic ASP to ASP.NET. Tool-assisted rewriting with gmStudio cuts effort to a fifth of a manual rewrite.

Other Migrations
Delphi, C++, COBOL, Java, PHP and Access, Oracle → PostgreSQL / SQL Server, removing IE mode and more.
Learn more →Test Automation (RPA)
Scenarios recorded on the current system run on the migrated system, and screens are compared to detect differences.

Post-Migration Operations
Keep maintaining after migration with version control, issue management and AI-assisted fixing — with in-house or VPN AI servers if source must stay private.
Learn more →In-house AI Server
For organizations that don’t want public AI reading their code, we build an AI server that stays in-house — from hardware selection to the code analysis and fixing environment, integrated with GitHub / GitLab and CI.
Learn more →The deadlines are already visible
Most legacy platforms won’t simply stop. The burden grows because the prerequisites for keeping them running keep increasing.
Oracle Forms 12c
Extended Support ends after just one year. Upgrading to 14c means replacing the whole stack, including WebLogic, the JDK and the database.
PowerBuilder 2022 / R2
Mainstream support has ended; PB 2019 and earlier are fully out of support. Deadlines apply per version, not per product.
Classic ASP (VBScript)
Microsoft plans to disable VBScript by default around 2027 and remove it later — and VBScript is what Classic ASP runs on.
VB6 IDE
IDE support has long ended. Running is not the same as maintainable: the tools and people who can change the code go first.

Why On Demand One
Specification kept
Layouts, function keys and focus order are reproduced, so users need almost no retraining. Up-to-date design documents are not a prerequisite.
Your source stays with you
We can estimate from XML extracted with Oracle’s own tools. Even in our AI-driven approach, your source code is not uploaded to an AI.
Back to in-house maintenance
The result is standard .NET / C# code that opens in Visual Studio. Our goal is a system your own team can maintain — not just a cutover.
Start small and see the quality for yourself
Asset inventory
We analyze screens, trigger lines and reports to size the migration (typically 1–2 weeks).
PoC (trial conversion)
We convert a few of your screens so you can check the conversion quality first-hand.
Plan and estimate
Based on the inventory and PoC, we present a migration plan and estimate.
Start with whether migration is feasible
Tell us the platform version and the number of screens, and we will send an initial answer. We are happy to sign an NDA first.
