How to Migrate Spaghetti to 304 Symfony 5 Controllers Over Weekend During Easter weekend, usually, people take a break and have a rest. Instead, we used these 4 days of holiday to migrate the 304-controller application. At least that was the goal on Friday. Me in my colleague in the migrated project accepted the challenge. We got into many minds and code-traps. We'd like to share this experience with you and inspire those who are still stuck on non-MVC code and think it might take weeks or even months to switch to a framework.
