Legacy Systems

Do you have a system no one really dares to touch?

One of those “it’s always been there” systems. The kind that works — as long as no one touches it. Most do. It handles something critical, day after day. But building anything new around it feels difficult. Maybe updating it has come up at some point. Maybe it’s even been discussed. But somehow, it never moved forward.

  • What if something breaks?
  • What if data is lost?
  • What if the new one doesn’t work the way it should?

So the system stays. And with it, a lot of good ideas never get implemented. Still - this isn’t a dead end. Often, it just takes a slightly different way of looking at the situation.

Modernising a legacy system is possible

That’s why there’s an assessment on this page you can go through yourself. It helps you understand what you actually have - without needing to decide anything yet. And if it does make sense to move forward, it can be done without taking unnecessary risks.

We can test solutions in a separate environment before anything touches production. There are also development environments available that keep the barrier to experimentation low.

Why a big bang, when you can move one piece at a time?

Gentle Exit

Gentle Exit is a phased way to modernize a legacy system without an uncontrolled big-bang replacement. The idea is to separate capabilities one part at a time so the old environment remains in use only for as long as it is genuinely needed.

The video gives a short overview of how Gentle Exit works in practice and why controlled separation is often safer than replacing the entire system at once.

Digiter is a Finnish non-profit association. The point of this assessment is to help you understand what kind of legacy situation you actually have and show that there is a safe way forward.

We do not collect data from the assessment automatically. You can choose to send the finished report to Digiter only if you want follow-up.
