Modernisation

The system holding you back that you cannot switch off

It has run for fifteen years, nobody dares touch it, and every change takes months. These are the systems we take over and modernise step by step.

A legacy system is rarely a bad system. Usually it is a system that worked well for too long, and along the way lost its documentation, its author and the ability for anyone to change it safely.

Replacing it in one step is the most expensive and riskiest route. We do the opposite: understand what the system does, stabilise it, then replace it piece by piece while the business keeps running.

How we do it

Takeover and assessment

We analyse the code, the database and actual usage. The result is documentation explaining what the system really does, often for the first time in its life.

Stabilisation

Before any change we deal with what is burning: security holes, failing backups, bottlenecks. That buys time for real modernisation.

Gradual replacement

New components take over one function at a time while the old system keeps running. There is no single cutover day where everything must work first time.

Data migration

Data is moved with verification and a rollback path. History is not lost. In most companies it is worth more than the system itself.

Frequently asked questions

Our system uses old technology. Is that a problem?

Not for assessment and takeover. We rarely recommend rewriting an entire system at once. It is usually better to keep the core that works and modernise the parts that actually change.

What if there is no documentation and no original author?

That is the normal situation. Documentation gets reconstructed from the code, the database and conversations with users. That is regularly the first phase of the project.

If you are looking for a partner able to see a project through to completion, we suggest an introductory meeting. The meeting is non-binding and serves to establish your requirements.
