The Problem

Why This Matters

Your VB6 app still runs the business. Your PHP 5 codebase has no tests. Rewriting from scratch takes 18 months and loses institutional knowledge. AI-assisted migration preserves behaviour, translates line-by-line, and generates tests that prove the new version matches the old.

Use Cases

What Teams Use This For

  • VB6 / VB.NET → C# or Python
  • PHP 5/7 → PHP 8.3 + Laravel / Symfony
  • Classic ASP → .NET Core or Node.js
  • Legacy SQL procedures → ORM-based modern architecture
  • jQuery monolith → React or Vue component library
  • Zero-test codebase → full unit + integration test suite
Deliverables

What You Receive

  • Codebase analysis report (complexity, dead code, dependencies)
  • AI-translated code in target language/framework
  • Behaviour-preserving test suite (unit + integration)
  • Side-by-side diff review for every migrated module
  • Deployment guide for new stack
