Migrating from eZ Publish 4 to eZ Publish 5: basic concepts

Architecturally, eZ Publish 5 is not a simple evolution but a revolution. eZ Publish 5 is based on the Symfony2 PHP framework and completely changes how you develop an eZ Publish website in a powerful and fun way. All versions of eZ Publish 5 take a dual-kernel approach that enables developers to work in both the “new stack” and the “legacy stack” at the same time. This ensures backwards compatibility and helps make the migration process to the new stack as smooth as possible.

This blog series is for existing eZ Publish 4 (or eZ Publish 5 legacy stack) users who are familiar with key eZ Publish concepts and are looking at migrating to the new stack in eZ Publish 5. In this series, we will explore how to migrate your legacy stack extensions to the new stack. We will explain the core new concepts and highlight the differences when compared to the legacy stack.
