Upgrading from 5.1.1.10 or 5.1.1.11 to the latest fix pack

Note: When you upgrade from Z Operational Log and Data Analytics 5.1.x.11 or earlier, the installed version of the Keycloak authentication service must be replaced with a later Keycloak version. The databases that are embedded in the old and new Keycloak versions are not compatible with each other. Therefore, the configuration and user data that is stored in the embedded database must be migrated during the product upgrade.

When you apply Z Operational Log and Data Analytics 5.1.x.13 or later, the deployment scripts for Docker and Podman automatically check for the existence of an older version of the Keycloak authentication service. If an older version is found, the deployment script automatically uses it to export its configuration and user data. After the installation of the new Keycloak version completes, the deployment script automatically imports the exported data into the new instance. This process does not require any user input or intervention.
