More details: http://2015.phpsummercamp.com/Programme/Migrating-to-Symfony-3 By Nicolas Grekas In this workshop, I'll tell how we migrated Symfony itself to Symfony 3.0. This story is about the process we invented so far to move forward, leaving the legacy behing us while allowing the ecosystem to follow a clear and continuous upgrade path. You'll also learn how to migrate your own applications to Symfony 3.0 and you'll practice this fresh knowledge on a legacy app prepared just for this exercice. But be warned: as of this workshop, Symfony 3.0 is still a work in progress and we'll live on the cutting edge of an unstable code base.
