Existing 2.3 Installations

If you haven't yet updated to 2.3.180, then you should review all links at the top of this post so that you are aware of all recent changes.

WARNING! If you have an existing Security Onion 2.3 installation and update to Security Onion 2.3.140 or higher, the Elastic components will undergo a major version upgrade to version 8. Please review and follow the steps at the link below. Failure to do so could result in loss of access to all data stored inside of Elastic and a non-functioning Security Onion installation.

Please be aware that custom settings in Kibana may be overwritten during upgrade. We recommend that you test the upgrade process on a test deployment before deploying to production. If you have a distributed deployment, then we recommend monitoring SOC Grid while your update is running to verify that all nodes update properly. If there are issues, you can review logs, services, and containers for any additional clues. If you need help, please see our support information below.

If you have custom Elasticsearch templates, please see:
