Demystifying eZPublish 5.xUpgrading opportunity ?
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
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)
