The size of the system is only part of it
The number of features and the amount of code matter, but complexity often lies in dependencies, integrations, data and business rules that have evolved over many years.
Documentation and knowledge matter
If no one knows the system anymore, some time needs to be spent understanding it. Good documentation and access to people who know the business can reduce that uncertainty.
How much needs to be modernised?
Upgrading a critical component is very different from rebuilding the entire system. A gradual modernisation often makes it possible to spread both cost and risk over time.
Also calculate the cost of doing nothing
If the system creates manual work, recurring errors or security risks, or blocks important changes, keeping it already comes at a cost. That cost needs to be included in the comparison.
Start with a brief assessment to guide your decision
Before you try to budget for a major modernisation project, it is often wise to map out the system, the risks and the main options. This gives you a much more realistic basis for planning the next step.
