Legacy systems

Rebuild an old system or keep improving it?

When a system has become hard to change, starting over is tempting. Sometimes it is the right choice. But there is often real value in what already works. The decision should be based on what the business needs, not how old the system is.

What still works well?

An older system can contain years of business logic and ways of working that users depend on. List what actually works before you estimate the cost of replacing anything.

What is the real problem?

Is the technology unreliable? Does every change take too long? Are you missing the skills you need? Or has your business outgrown what the system can do? Different problems need different solutions.

When further development makes sense

If the foundation is stable and the problems are limited to specific areas, it is often possible to modernise and develop the system step by step. This lets you keep what works and reduce risks over time.

When a rebuild may be right

If the system's basic design blocks almost every important change, the technology can no longer be supported or the business needs something completely different, a more extensive rebuild may be justified.

Estimate the full cost of the change

A new system costs more than the development itself. Data needs moving, integrations need rebuilding, users need retraining and the business needs to keep running during the transition. So compare the options based on their full impact.

You don't need to decide before you have the facts

Reviewing where things stand can give you a clear basis for deciding what to keep, change or replace.
