Why this matters
Business logic in MS-DOS, VB6, or Delphi applications often represents your most valuable intellectual property. Re-implementing it from scratch is risky and expensive. By preserving it during modernization, we protect the work that makes your operation unique while removing the platform constraints that limit it.
How we deliver
We start with source analysis, dependency mapping, and rule extraction. Rules are documented, tested against the legacy system, then re-implemented on the modern platform with paired tests proving behavioral parity. Nothing ships until behavior matches.
The outcome
You get a modern, supported codebase that behaves exactly like the legacy system (same edge cases, same calculations, same workflow), but on current technology, running on current hardware, with tests that will catch regressions for years to come.
