Hi there, I can help you migrate your PHP project from version 7.2 to the latest stable release while ensuring zero downtime for your production environment. I have extensive experience upgrading legacy PHP applications, resolving deprecated functions, updating dependencies, and performing thorough post-migration testing. I follow a structured approach: first I audit your code and dependencies, then create a staging environment to implement the upgrade safely, resolve incompatibilities, and run comprehensive tests. Once confirmed, I’ll deploy to production with minimal risk and provide a rollback plan.
