Overview
Old software, new possibilities
Legacy applications often still run critical parts of the business, but they become harder to maintain every year: unsupported PHP versions, security vulnerabilities, slow performance, no mobile support and developers who no longer want to touch the code.
We modernise legacy systems incrementally. We audit what exists, keep what works, and migrate the rest to modern frameworks and infrastructure in safe stages — so the business keeps running and risk stays low.

Our approach
How we think about every project
Strategy first
We start with your business goals, users and constraints, and turn them into a clear scope, architecture and roadmap before writing code.
Solid engineering
Clean architecture, code reviews, automated tests and secure coding practices keep your product fast, stable and easy to extend.

We interviewed shops in many countries, and finally we got some professional help in making a decision. We decided to go ahead with Webcarving in India. It is really the best decision we have made so far for the business.

Frequently asked questions
Should we rebuild from scratch or modernise step by step?
Step-by-step modernisation is usually lower risk and delivers value sooner. A full rebuild can make sense when the existing code is very small or impossible to maintain. The audit shows which approach fits.
Will our users experience downtime?
We plan releases to avoid disruption, using staged rollouts and scheduled maintenance windows for any unavoidable cut-overs.
Can you work on code written by another company?
Yes. Most modernisation projects involve code written by others; we start by documenting and testing it.
Our PHP version is no longer supported. Is that urgent?
Unsupported PHP versions no longer receive security fixes, and hosting providers eventually remove them. Upgrading should be planned soon to avoid security and availability risks.
