Update and Installation Portal Open-Xchange Server v6.22

The new Open-Xchange Server v6.22 is the first step on the way to the next generation Open-Xchange Server 7. The update provides a new and improved Open-Xchange Server backend with enhancements for both generations.

Especially on the backend, Open-Xchange implemented various changes and improvements like a new and clear structure for the configuration files and packages, an improved exception framework, unified OSGi, etc.

On this portal you can find an overview of the differences between the Open-Xchange 6.20.x and the Open-Xchange v.6.22 backend. There are new requirements, update guides, and multiple other changes.

Please read the different articles and manuals regarding the update. We encourage administrators of Open-Xchange 6 v6.20.x to install this update. The further feature development will be based on v6.22

Furthermore, Open-Xchange provides the complete v6.22 materials as a document which is available here: Software Repository.
