Frequently asked questions
Questions about modernization and evolution
Is it worth modernizing legacy software?
Yes, when the system still generates value for the business but limits growth due to maintenance cost, slowness or difficulty evolving. Incremental modernization reduces operational risk and preserves the existing business knowledge, instead of discarding it in a risky rewrite.
When to refactor or rewrite?
Refactoring is recommended when the architecture allows incremental evolution with low risk. Rewriting is only justified when the technology base is unsustainable or blocks critical goals. In most cases, incremental evolution delivers value faster and with lower risk.
Does AI really speed up development?
Yes. AI accelerates documentation, testing, QA and code generation - always under senior specialist review. Our principle is clear: AI accelerates; engineering ensures quality, security and sustainable architecture.
How does evolutionary maintenance work?
It's continuous software maintenance combined with planned strategic improvements, performance monitoring and architecture evolution over time, ensuring the system keeps up with the growth of the business.
How much does it cost to modernize a system?
The cost depends on the size, complexity and current state of the system. We start with a technical diagnosis that maps bottlenecks and defines a prioritized roadmap, allowing incremental, predictable investment instead of a single high-risk project.
How to reduce risks in legacy systems?
With technical diagnosis, test coverage, incremental evolution, documentation and reduced dependence on a few developers. A full rewrite is avoided whenever possible, mitigating operational risk and keeping the system in production throughout the transition.
