Modernising legacy software, without downtime

Your business runs on custom software built years ago. It still works - but nobody dares touch it anymore. We modernise outdated applications step by step, while your business keeps running.

Sound familiar?

It still works, so we leave it alone

Many businesses run on software that was once custom-built. A planning system, a client portal, an internal application. It has done its job for years - so why touch it?

Because it is quietly becoming a risk. Old software often runs on old PHP versions that no longer receive security updates. Hackers know the weak spots. The original developer is out of the picture, and every change feels like surgery without anaesthesia.

The longer you wait, the bigger the risk - and the more expensive the catch-up. But fortunately, replacing everything at once is not necessary.

Our approach

Modernising step by step

  1. 1

    Analysis

    We examine the application: which technology, which versions, where are the risks? You get an honest picture of the state of your software.

  2. 2

    A phased plan

    We create a plan that fits your budget and your business. The biggest risks first, then the rest. No big bang, no downtime.

  3. 3

    Modernise

    We bring the software up to modern, supported technology - usually Laravel. Piece by piece, while the old system keeps running.

  4. 4

    Stay current

    After modernisation we keep the software up to date with maintenance and updates. So your application never ends up in this situation again.

Why Nettt

Modernisation without surprises

  • PHP and Laravel specialists

    Outdated PHP applications are our daily work. We know how old code fits together and how to modernise it safely.

  • Your business keeps running

    We modernise in phases. Staff keep working as usual; the old system is only switched off once the new one has proven itself.

  • Risks first

    We start where the danger is: outdated versions, leaks, vulnerable components. So the biggest worry disappears fastest.

  • Integrations keep working

    Does your software talk to your accounting or other systems? We carry those integrations through the modernisation - or improve them.

Frequently asked questions

Frequently asked questions about modernising software

A few signals: the software runs on an old PHP version (7.4 or lower), no updates have been done for years, or the original developer is no longer involved. Not sure? We do a free check.

Not necessarily. Sometimes the foundation is solid and updating the technology is enough. Sometimes rebuilding certain parts is smarter. After the analysis you see exactly what we recommend and why.

No. We modernise alongside the existing system and only switch over once everything is tested. Your staff will notice little to nothing.

That varies greatly per application. That is why we start with an analysis: afterwards you know exactly what is needed, in which order, and what each phase costs. You stay in control of the budget.
