Software modernization: your business keeps running while the old goes away

In a software modernization with Aqtelo, your business keeps running without interruption. New parts gradually take over the tasks of your old system until it has nothing left to do. There is no big cutover day when everything has to work at once, and you decide after every step how to continue.

What you get from modernization

Maintenance
Until now, you pay a lot for every small change because hardly anyone still knows the system. Afterward, your team or any other partner can work on it.
New requirements
Until now, an interface to the online shop or a mobile view fails because of the old system. Afterward, you can connect what your business needs, including AI agents on your data.
Dependency
Until now, everything hangs on one person who understands the system. Afterward, the knowledge is documented in writing.
Security
Until now, gaps stay open because updates are missing. Afterward, our Security area tests every new part before it goes live.

Why a rebuild all at once is so risky

Many companies have been putting off replacing their legacy system for years. The reason is understandable: a complete rebuild means a long time without visible progress and then a cutover day when everything has to work at once. If something goes wrong, orders, invoices or production come to a halt.

We take a different approach. Think of your system as a house that stays occupied while it is renovated room by room. One area after another moves over, for example the quote calculation first, then an interface. For a while, old and new run side by side until the results match. Only then is the old part switched off. After every step, you have a working system.

In the intro call we set your goal together.

You learn which first step is worth it for you.

Why Aqtelo is the right partner for your modernization

The goal is set beforehand.
Together we decide what the first step should deliver, for example hours saved in maintenance or an interface that was missing until now.
Start small.
We begin with a clearly defined area. We continue only once it has proven itself.
Faster through old code.
Where nobody knows anymore what a function does, AI helps us read it. A person checks every change before it goes live.
One fixed contact.
One person guides you, in German, English or Portuguese. Behind them stands a select network of experienced specialists.
Tested before it goes live.
Security tests every new part. With old systems in particular, this turns up gaps that went unnoticed for a long time.
Everything belongs to you.
Code, data and documentation are in your name. You can continue at any time with your own team or another partner.
In-person meetings in the EU
If you want to discuss the project across the table.

How we work together

  1. UnderstandWe document what your system does, which data it uses and who depends on it.
  2. Choose the first areaOne that is clearly bounded and brings a lot.
  3. Build new and run in parallelOld and new work side by side until the results match.
  4. Switch over and switch offOnly then does the old part go offline.
  5. DecideYou choose whether, and which, area follows next.

What can we help with?

You can select more than one

What you probably want to know

It depends on the size and condition of your system. After the analysis you get a quote for the first area, with a goal and review dates. Every further step is planned separately.

We choose a clearly bounded area as the first one. That way you see early how a new part works in operation. We set the schedule after the analysis.

It stays your data and moves in a controlled way into the new part. Where we use AI, your data trains no model and stays in the EU where possible.

Where screens or workflows change, yes, but in small steps rather than all at once. We involve the people who work with the system.

Old and new run in parallel for a while. If a difference shows up, the old part keeps working until the error is fixed. Your business doesn't stop.

Yes. Every step leaves behind a working system. After each area, you decide whether and how to continue.
