Upgrade Elastic on-prem

edit

Once you are prepared to upgrade, you will need to upgrade each of your Elastic components individually.

  1. Consider closing machine learning jobs before you start the upgrade process. While machine learning jobs can continue to run during a rolling upgrade, it increases the overhead on the cluster during the upgrade process.

  2. Upgrade the components of your Elastic Stack in the following order:

    1. Elasticsearch Hadoop: install instructions
    2. Elasticsearch: upgrade instructions
    3. Kibana: upgrade instructions
    4. Java API Client: dependency configuration
    5. Logstash: upgrade instructions
    6. Beats: upgrade instructions
    7. Elastic Agent: upgrade instructions
