AI-Assisted Legacy Modernisation

In most organisations, the most valuable knowledge sits inside an old system that nobody dares to touch. AI-assisted coding tools let us understand, document and migrate these systems much faster. The speed comes from AI; the correctness comes from engineering discipline. Every change is verified by a test, and every step can be undone.

What we do

Codebase analysis

With AI-assisted tools, we extract dependencies, business rules and unused code, and produce an up-to-date map and documentation of the system.

Assurance through tests

Before migrating, we generate tests that capture the current behaviour. We don't move on to the next step until the new system gives the same results.

Incremental migration

Instead of replacing the system in one go, we move it to the new architecture piece by piece. With the old and the new running side by side, the risk stays low.

Language and framework migration

We move legacy .NET Framework, Java, Delphi, VB6 or PHP applications to current languages and frameworks.

Data migration

We clean up the data model, verify the migration scripts and prepare a rollback plan for cut-over day.

Handover to your team

We document and hand over the new system so that your team can maintain it with AI-assisted tools.

Applied as the project requires.

Our approach

AI writes code quickly, but it is an engineer who decides what is right. We put every generated change through tests, read it in code review and take it live in small steps.

We treat modernisation not as a one-off project but as a move to a way of working that your team can sustain.

Where we apply it

Defence & Aerospace

Electronics, embedded software and mechanics designed for harsh environments, long product life and rigorous documentation.

Industrial Automation

Control boards, embedded software and operator interfaces that run on the production line for years without interruption.

Automotive

Vehicle electronics, embedded software and test systems, built with functional safety and cybersecurity in mind.

Engineering it draws on

Systems Engineering & Architecture

We think about the product as a whole before we divide it into parts. Requirements, architecture and interfaces come together in the same picture.
