Update nJAMS Server step by step#

Follow these instructions to update nJAMS Server from version 4.x to 5.0, while keep on using existing Elasticsearch 5, respectively 6.

Caution

If the Elastic cluster of your current nJAMS instance still runs Elasticsearch version 2, you have to upgrade your Elastic cluster first.

The update process to version 5.0 includes an update of WildFly Application Server to version 16. The existing installation of WildFly 10 will remain just in case.

Start nJAMS Server installer
