Update and Installation 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 page 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.

Improvements Overview of 6.20.x to 6.22 Backend

Open-Xchange provides an overview page regarding the main improvements of the new v6.22. Please have a look at Backend Improvements 6.22

Configuration Changes

The overview page provides a list of

  • unchanged config files with old and new location
    • push.properties renamed to push-udp.properties
  • completely new config files
  • config files that do not longer exist
  • merged / split config files
  • config options which need to be changed and their containing files

If you have any configuration management or templating system for automatic deployment of OX instances in place, theses changes mean that you will have to adapt that system to the new configuration file tree.

Packages changes

The overview page provides a list of

  • new packages and metapackages with short description
  • removed metapackages
  • remaining metapackages and what they do

We encourage administrators of Open-Xchange v6.20.x to read the list before updating to Open-Xchange v6.22.

If you have any custom system for automatic installation and deployment of OX instances in place, it is very likely that you need to adapt your system to the new package structure.

No separate admin daemon

Admin functionality will now be a part of the Groupware Process as optional bundle. This means the former, as root running, Admin daemon will no longer exist.

following are potential pitfalls :

  • ox-admin-scriptconf.sh is merged to /opt/open-xchange/etc/ox-scriptconf.sh, check NRFILES and Memory setting to fit the environment.
  • If /etc/security/limits.conf does set limits for the open-xchange user, those need to be adopted.
  • administrative tasks are now executed as user open-xchange (for example the filestore mount is no longer accessed as root).
  • The mutual process is not able to open tcp sockets below 1024.
  • Monitoring for the admin process is no longer needed.

Startup Scripts

The overview page provides a list of

  • startup scripts

We encourage administrators of Open-Xchange v6.20.x to read the [list] before updating to Open-Xchange v6.22.

Changes to programming APIs which might break custom plugins to the OX Server

The overview page provides a list of

  • changes to exception handling & other code changes that break customer's custom developments

We encourage administrators of Open-Xchange v6.20.x to read the [list] before updating to Open-Xchange v6.22.

Migration from OLOX1 to OLOX2

Migration Path

Open-Xchange will discontinue the support for OXtender 1 for Microsoft Outlook with the new release v6.22. Additional, at the new backend, the Open-Xchange WebDAV XML API will no longer be officially supported. Open-Xchange will provide an upgrade path to the OXtender 2 for Microsoft Outlook.

If the user installs the upcoming OLOX1 6.18.19 we will provide the following information to the user when trying to sync against the OX server >= 6.22. Open-Xchange provides via a pop-up window at the product the following migration possibilities:

  • User can use the OXUpdater to install the new version
  • User can directly start installing by clicking on a provided link

If the user closes the pop-up window, the OLOX 1 will be deactivated for the current session and profil. After installing OLOX2 and starting Outlook the user has to select the new OLOX2 profile and the migration is done.

Known Issues

  • After the start of the new OLOX 2 profile, contacts, appointments and tasks will be synchronized
  • Per default server configuration, mails older as one year will be synchronized
  • Notice and Journal information won't be synchronized. It is possible to export and import the information via the Outlook functionalities
