  1. The minimum requirement for updating to nJAMS Server 5.1 is any nJAMS Server version running with Elasticsearch 6. If you are currnetly on nJAMS Server 4.4, please update to nJAMS Server 5.0 first as an intermediate step, before you start updating to nJAMS Server 5.1.

  2. You can update from nJAMS Server 5.0 to version 5.1 by deploying the update file (WAR file) for nJAMS Server 5.1 at Administration > System control > Deployment.

  3. Make sure your added 3rd party libraries have to be Java 11 compatible

    Since version 5.0 nJAMS Server runs with OpenJDK 11. That means used 3rd party libraries in your current nJAMS instance must be Java 11 compatible. If you are updating your existing nJAMS Server instance from version 4.x, verify compatibility of the currently used JDBC driver. nJAMS installer allows to update your current instance, while replacing the JDBC driver with a newer version.
