If a legacy system is still working reliably, should a business replace it just because the technology is outdated?
Genuinely asking
- A 15–20-year-old system may still be doing its job perfectly.
- Replacing it can introduce cost, migration risks, downtime, and employee training.
- But legacy systems can become difficult to maintain and integrate with modern APIs, cloud services, mobile apps, and etc.
- At what point does it still works become a business risk?
- Is modernization/migration better than completely rebuilding from scratch?
