Le document propose une explication des changements majeurs entre ezpublish 4.x et 5.x, notamment la transition vers Twig et Symfony, ainsi que l'utilisation de nouvelles API. Il aborde également les opportunités de mise à niveau pour les développeurs souhaitant moderniser leurs applications. Enfin, un partenariat est suggéré pour intégrer un système de mesure des performances et ajuster les processus de développement et de déploiement.

Upgrading opportunity ?

30. Upgrading effort ?
You can migrate your features & existing layers step-by-step (and
keep a fallback for other features)
If we consider a full migration, you will need to :
- Replace all the templating with Twig+PHP controller
- Rebuild all the custom PHP dev (modules, scripts, datatypes,
template operators, etc.) with new symfony+public API logical
- Redesign your cache logical with HTTP cache
- Add Varnish on top of your platform
If we consider a full migration, you don't have to :
Think about the content & the back office

31. Upgrading oppotunity ?
Good if you need to redbuild the front-end for any
reasons : (responsive, new design, need ESI massively, etc),
opportuniy to rebuild with controllers+Twig
Good if you need a RESTful API for external App (mobile,
middleware)
Good if you have many new custom development to do.
Symfony will fit with the best practices (testing, injection
dependency)
