Legacy software, modern foundation

Your old system works, but it is getting harder to maintain, integrate and secure. We modernize it step by step, keeping the business rules that took years to build.

Modernize without stopping the business

Many companies still run on systems written in Delphi, VB6, Access or early .NET. Rewriting everything at once is risky: rules get lost, projects drag on, and the big switch-over can stop the operation.

We use AI-assisted analysis to read the existing code and document its rules, then replace the system module by module, with old and new running side by side until it is safe to switch off the legacy.

Our approach

Legacy analysis

AI-assisted code reading to map modules, data and rules.

Target architecture

Modern stack and migration order defined with you.

Incremental migration

Each new module goes live alongside the old system.

Safe decommission

Switch off the legacy only when everything is validated.
