= Update of Open-Xchange Server v6.20 to v6.22 on CentOS 5 =

This article will guide you through the update of an existing Open-Xchange Server 6 installation to the newest major release, v6.22.


= Supported update path =

Please note that the update to v6.22 is only supported from an installed version 6.20.7. If you have an earlier version of Open-Xchange Server 6 installed, please update to the latest release of v6.20.7 before attempting an update to v6.22.
Also the update to 6.22.0 must be installed before doing further updates to 6.22.x.

The latest v6.20.7 release will remain accessible on our servers. If you need to access the repository after the release of v6.22, please use the following lines in your <code>yum</code> repository configuration to access v6.20 packages:

Start a console and change the software repository file for Open-Xchange:
  <code>$ vim /etc/yum.repos.d/ox.repo</code>

= Requirements =
* An Open-Xchange Server installation v6.20.7. This update guide is valid for a system installed through our [[Open-Xchange_Installation_Guide_for_CentOS_5|Download and Installation Guide for CentOS 5]]
* If you have custom packages done by Open-Xchange, please discuss with your Open-Xchange contact when these packages are available for 6.22. Do not attempt the update earlier
* If you have built custom packages yourself which install config files in the OX config tree, please check the page [[6.22_Packaging_Changes|v6.22 Packaging Changes]]
* If you have custom plugins written by yourself which depend on Open-Xchange Server OSGI bundles, check the pages  [[6.22_Packaging_Changes|v6.22 Packaging Changes]] and  [[6.22_Necessary_Code_Changes|v6.22 Necessary Code Changes]] for changes you might need to do.
* Custom packages built for 6.20.7 or earlier might not work with 6.22.
* As for every update we strongly recommend that you make a backup of your system(s) before you proceed.

Please note that frontend and backend packages are now provided from two different repositories. Depending on your setup and the packages installed on the specific system you're updating it is possible that you only need one of these repositories. All packages providing <code>open-xchange-admin</code> functionality are included in the <code>backend</code> repository.

= Updating repositories and update packages =

Reload the package index and update all installed packages:

 $ yum update
 $ yum upgrade

= Install additional language packages if necessary =

Starting with v6.22 the localization files for German, French and British English are no longer part of the core packages. This change was necessary to allow customers to uninstall these languages when they are not needed. If you want to offer German, French and/or British English to your customers as language option, you need to install the corresponding packages after the update.

For German:

 $ yum install open-xchange-l10n-de-de open-xchange-gui-l10n-de-de

For French:

  $ yum install open-xchange-l10n-fr-fr open-xchange-gui-l10n-fr-fr

For British English:

  $ yum install open-xchange-gui-l10n-en-gb


= Adjusting runlevel configuration =

Starting with v6.22 there are no longer two separate process, but only one, <code>open-xchange</code>. Therefore, the runlevel configuration needs to be adjusted:

 $ chkconfig --level 345 open-xchange on

NOTE: Admin functionality is only available if the package <code>open-xchange-admin</code> is installed. If you are updating a system without admin packages installed it still won't have admin functionality after the update.


= Restart Open-Xchange =

To restart Open-Xchange Server after the update, run

 $ /etc/init.d/open-xchange restart

This script will check on startup if the old processes for <code>open-xchange-groupware</code> and <code>open-xchange-admin</code> are running, and stops them if they are. You might still want to check with

 $ ps aux | grep open-xchange

that there is now only one process running Open-Xchange Server.

= Leftover configuration files and runtime data =

After the update you may see leftover configuration files and runtime data below <code>/opt/open-xchange/etc</code>.

Some of these files belong to packages which have been uninstalled during the update.

Other orphaned files may be runtime data or temporary files which do not belong to any package and therefore couldn't be removed during the package update.

Finally, there may be backup files created by the package manager during earlier updates.

It is safe to remove:

* All files and subdirectories below:

 /opt/open-xchange/etc/admindaemon
 /opt/open-xchange/etc/common
 /opt/open-xchange/etc/groupware

unless you have built your own packages which install files into these directories.

* All files ending in <code>.rpmsave</code> or <code>.rpmnew</code> once you are confident that your configuration is working after the update.
