Upgrading Legacy to the Latest PHP Version | Anna Filina | phpday 2024

Your application runs on an old PHP version that is about to go out of support. How to upgrade without breaking the application? You will need the right tools for detecting and fixing those issues, as well as a way to verify that the application is still working correctly. In this presentation, I will share the strategy that I employed when upgrading millions of lines of untested code.
Anna Filina is Legacy Archaeologist @ Filina Consulting.
