Modernization

Modernize a legacy system while keeping risk in check.

An old system holds years of accumulated business rules. AI accelerates understanding them and transforming the code. But a migration only succeeds with an integrator who knows how to manage risk — that has been our craft since 2012.

The real risk in a migration is a business one.

Rewriting code, we know how to do. The danger is losing an implicit rule — an edge case, a regulatory exception, a buried check — on which a critical operation depends.

AI reads and explains existing code at a speed no one could match by hand, reconstructs the application map and surfaces the business rules. Our experience as an integrator secures the transformation.

Typical situations
  • System stuck on limiting technologies
  • Undocumented business rules
  • Departure of long-standing experts
  • Migration to cloud / microservices
  • Need to open the system up via APIs
Our method

From code archaeology to a modern architecture.

01

Understand

AI-assisted analysis of the legacy code, application mapping, extraction of business rules.

02

Secure

Documenting existing behavior and non-regression tests: we lock down what the system does before changing it.

03

Rewrite in stages

Assisted refactoring, progressive shift to APIs, cloud and microservices — with the system still running.

AI accelerates the analysis and the transformation. Our systems expertise secures the migration.

Is a system holding you back as much as it keeps you running?

We assess the real state of your legacy, the level of risk and a progressive modernization path.
