Existing 2.3 Installations

WARNING! If you have an existing Security Onion 2.3 installation that hasn't yet been updated to version 2.3.140 or higher, then you should be aware that 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.

https://docs.securityonion.net/en/2.3/soup.html#elastic-8

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:
https://docs.securityonion.net/en/2.3/elasticsearch.html#custom-templates
