Legacy application modernization

We bring your old application into the present without stopping the business. We work incrementally, with the strangler-fig approach, replacing outdated code piece by piece so the migration is safe and free of surprises.

Legacy application modernization

What's included

  • Analysis of the current system and dependency mapping
  • Incremental modernization strategy (strangler-fig)
  • Data and integration migration without loss
  • Rewriting critical modules on current technologies
  • Automated tests and zero-downtime delivery
  • Documentation and knowledge transfer to your team

Benefits

No downtime

We migrate step by step, and the application stays functional throughout the process.

Reduced risk

We replace gradually, not all at once, so each step can be tested and rolled back if needed.

Costs under control

We prioritize what adds value now and spread the investment, without a costly rewrite from scratch.

Frequently asked questions

Do we have to rewrite everything from scratch?

Almost never. We prefer incremental modernization: we keep what works and replace only the problematic parts, gradually.

Can the application stay online during migration?

Yes. The strangler-fig approach lets us run the old and new systems in parallel and switch over gradually, without downtime.

How long does a modernization take?

It depends on the size of the system, but the first modernized modules usually reach production in a few weeks, not months.
