Smooth Transition and Long-Term Support
Drawing on lessons from the past, particularly the transition from Craft 2 to 3, Pixel & Tonic recognizes that such a significant upgrade can pose challenges for existing projects. To ease the transition from Craft 5 to 6, a compatibility layer has been announced.This layer will allow many existing plugins to run on Craft 6 with minimal or even no code changes, significantly lowering the upgrade barrier.
Additionally, an important decision has been made for all Craft 5 users: Craft 5 will become a Long-Term Support (LTS) version. This means it will continue to receive maintenance and critical security updates for five years after the release of Craft 6. Users can transition at their own pace without feeling pressured to upgrade immediately.
