Update

To update an existing Universal Messenger installation download the installation packet for the desired version and run the installer. If you select the existing base directory as the target it will recognize the installed version and run an update.

The update will replace all existing program files, core apps and libraries shipped with the installer. If necessary, it will also update the database schema.

It will not touch the configuration or individual extensions or project files. In some cases, however, it is necessary to make changes to your configuration or update your individual extensions or functions which use the UM CSE API. Please carefully read the Release Notes (Universal Messenger) before each update.

You can find additional information in the installation documentation: https://www.universal-messenger.de/knowledge-base/intern/doc-en/Installation/Ablauf_eines_Updates.html

We also recommend updating the Universal Messenger apps (Newsletter, Contact form, Event management, etc.) if possible as they will also not be automatically updated by the installer. Usually there are individual update information and release notes for each app, the general procedure is described in the following documentation: https://www.universal-messenger.de/knowledge-base/intern/doc-en/Apps/Installation_and_Update.html
