  2. Download the REST API web application archive from our Artifact Repository Alternatively, switch to the private repository for the enterprise version (credentials from license required).

  3. Download the CadenzaFlow web application archive from our Artifact Repository. Alternatively, switch to the private repository for the enterprise version (credentials from license required). Choose accordingly:

    • For Tomcat 10, the name of the artifact is $PLATFORM_VERSION/cadenzaflow-webapp-tomcat-jakarta-$PLATFORM_VERSION.war.
    • For Tomcat 9, the name of the artifact is $PLATFORM_VERSION/cadenzaflow-webapp-tomcat-$PLATFORM_VERSION.war.

  4. Deploy the web application archive to your Tomcat instance.

Update Cockpit, Tasklist, and Admin
