Upgrading to Symfony 8

Ready to upgrade to Symfony 8? Let’s do it - without the stress.

In this course, we’ll walk step-by-step through upgrading a real Symfony 7 application to Symfony 8. No fluff, no detours into every shiny new feature - just a focused, practical path to getting your app upgraded safely and confidently.

We’ll handle deprecations, update dependencies, and smooth out the rough edges that pop up along the way. And along the journey, we’ll tackle one of the biggest ecosystem shifts: upgrading Doctrine to take advantage of PHP 8.4’s native lazy proxies - goodbye generated proxy classes, hello simpler, faster magic.

Whether you’re maintaining a long-lived app or just like staying on the latest version, this course will give you a clear, battle-tested upgrade path.
