The service pack can be determined in checking the version number of the <tt>open-xchange</tt> package. The second digit relates to the SP version. The following table shows a list of package versions and the corresponding SP number:

Updating Open-Xchange Server packages

This article describes how to update Open-Xchange Server packages from one service pack to another.

How to get updates?

Open-Xchange Server 6 updates can be accessed by customers with a valid license for

  • OX SE
  • OX HE

You need to configure the OXReportClient.

Please note: The update to v6.22 is only supported from an installed version 6.20.7 or later. If you have an earlier version of Open-Xchange Server 6 installed, please update to the latest release of v6.20 before attempting an update to v6.22.

Updating Open-Xchange Server Packages 6.20.x

Installing Updates

A new service pack usually introduces new packages and requires configuration changes. To get all required new packages and configuration changes, the following must be done when installing updates.

On Debian based distributions

Add the following entry to /etc/apt/sources.list.d/open-xchange.list

deb http://LDBACCOUNT:LDBPASSWORD@software.open-xchange.com/OX6/updates/backend/DebianJessie/ /
deb http://LDBACCOUNT:LDBPASSWORD@software.open-xchange.com/OX6/updates/frontend/DebianJessie/ /

Then run

$ apt-get update
$ apt-get dist-upgrade

If you want to see, what apt-get is going to do without actually doing it, you can run:

$ apt-get dist-upgrade -s

After the new packages are installed, the groupware and admin process needs a restart:

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

NOTE: Please take care, that you do not restart Open-Xchange during the process where it updates it's database. A database update can happen after installing minor or major updates. As soon as the first user tries to log in to the system or if any provisioning action is done, this update starts.

On RPM based distributions

RHEL6/CentOS6

Add the following entry to /etc/yum.repos.d/ox.repo:

[ox-updates]
name=Open-Xchange Updates
baseurl=http://LDBACCOUNT:LDBPASSWORD@software.open-xchange.com/OX6/updates/backend/RHEL6/
baseurl=http://LDBACCOUNT:LDBPASSWORD@software.open-xchange.com/OX6/updates/frontend/RHEL6/
gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m


and run

$ yum update
$ yum upgrade

After the new packages are installed, the groupware and admin process needs a restart:

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

NOTE: Please take care, that you do not restart Open-Xchange during the process where it updates it's database. A database update can happen after installing minor or major updates. As soon as the first user tries to log in to the system or if any provisioning action is done, this update starts.

RHEL7/CentOS7

Add the following entry to /etc/yum.repos.d/ox.repo:

[ox-updates]

baseurl=http://LDBACCOUNT:LDBPASSWORD@software.open-xchange.com/OX6/updates/backend/RHEL7/

gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m


and run

$ yum update
$ yum upgrade

After the new packages are installed, the groupware and admin process needs a restart:

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

NOTE: Please take care, that you do not restart Open-Xchange during the process where it updates it's database. A database update can happen after installing minor or major updates. As soon as the first user tries to log in to the system or if any provisioning action is done, this update starts.

Installing Updates

A new service pack usually introduces new packages and requires configuration changes. To get all required new packages and configuration changes, the following must be done when installing updates.

On Debian based distributions

Add the following entry to /etc/apt/sources.list.d/open-xchange.list

deb http://LDBACCOUNT:LDBPASSWORD@software.open-xchange.com/OX6/6.22/updates/frontend/DebianJessie/ /

Then run

$ apt-get update
$ apt-get dist-upgrade

If you want to see, what apt-get is going to do without actually doing it, you can run:

$ apt-get dist-upgrade -s

After the new packages are installed, the server process needs a restart:

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

$ zypper dup -r UPDATESBACKEND
$ zypper dup -r UPDATESFRONTEND


You might need to run

$ zypper ref

to update the repository metadata before running zypper up.

After the new packages are installed, the server process needs a restart:

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

NOTE: Please take care, that you do not restart Open-Xchange during the process where it updates it's database. A database update can happen after installing minor or major updates. As soon as the first user tries to log in to the system or if any provisioning action is done, this update starts.
