Update to 7.0#


We highly recommend to update on a test instance first.

This documentation explains how to update to the Znuny 7.0 release.

Please note that your current system needs to be a

  • Znuny LTS 6.5.x

to perform the update. We do not support direct updates from any version before Znuny LTS 6.5.

IMPORTANT: The base settings have been changed to reflect the new product name. This means, that you may either switch to the new user znuny and new base dir /opt/znuny, or keep your old settings. If you decide to change, you’ll need to create the new user, and modify your Config.pm settings before continuing. This upgrading instruction now uses <HOME_DIR> and <APP_USER>.


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

Check if every add-on your are using is available for version 7.0. 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.
