An old application that works is not necessarily a safe one
The sentence we hear most often is: it has worked for eight years, why change it? The argument is right operationally and wrong in terms of risk.
An application on a PHP or framework version that has left support no longer receives security fixes. The risk is not that it breaks by itself, but that one day someone finds a publicly known vulnerability with no available fix, and you hear about it from your customers.
- You can no longer update the server without the application stopping
- You cannot find developers willing to work on that version
- Every new feature takes several times longer than it should
- Your hosting provider announces the version is being withdrawn
A staged migration, not an overnight one
A complete rewrite in one move is the riskiest option and the one most often proposed. We avoid it wherever we can.
- First we bring the application under control: repository, test environment, a copy of the database
- We cover the critical areas with automated tests, so we see immediately what breaks
- We update versions step by step, checking after each step
- We rewrite only the components that genuinely block further development
- We go to production in an agreed window, with a rollback plan ready
What you gain in concrete terms
After modernisation the application often looks the same to its users. The difference shows elsewhere: security updates can be installed, new features take days instead of weeks, and hosting no longer depends on a version nobody offers any more.
