Update to 6.2

Update to 6.2#

Note

We highly recommend to update on a test instance first.

This documentation explains how to update to the Znuny 6.2 release.

Please note that your current system needs to be a:

  • Znuny 6.1.x

to perform the update. We do not support direct updates from any version of OTRS, ((OTRS)) Community Edition, Znuny LTS or before 6.1

Preparations#

Before the update can started we need to perform some tasks to prepare the update.

You should or should have entered a scheduled maintenance time period in the admin area. Login as your admin user, select the active maintenance window and kill all sessions but your own. Now only administrators can login.

Maintenance Session Managment

Maintenance Session Managment#

Create a backup of the database, the application and all data, especially the attachments.

Check if every add-on your are using is available for version 6.2. You don’t have to care on packages which are already integrated, see the list of them in the release notes.

Create a backup of the database, the application and all data, especially the attachments.

Update installed packages#

Note

Packages for earlier version of Znuny LTS (6.0.x) Znuny are might not compatible with Znuny 6.2 and have to be updated.

Note

UpgradeAll should only be performed, after your target version has been reached.

Note

UpgradeAll can fail, if repositories are not reachable or configured, versions for your framework are not available, or packages have been renamed. In this case, you should upgarde your packages manually via the commandline or by installing/updating them via the package manager.

# Fill the crontab and wait(!) at least 5 minutes that the Daemon is started via cron
su -c 'bin/Cron.sh start' - otrs

systemctl start httpd # CentOS / RHEL
systemctl start apache2 # Debian / Ubuntu

# Start your local MTA, mostly Postfix, sometimes Exim or Sendmail
systemctl start postfix

Deactivate maintenance#

Don’t forget to deactivate the scheduled maintenance, so that your users and customers can login again.
