โ > WARNING! - ElastiFlow v4.0.0 is a major release, and now supports Elastic Common Schema (ECS). Due to significant data model changes there is no upgrade/migration from ElastiFlow 3.x. You should either remove all 3.x indices or deploy ElastiFlow 4.0.0 to a separate environment.
๐ฅ Breaking Changes
๐ ElastiFlow v4.0.0 is built for Elasticsearch and Kibana 7.8.1 and later. No earlier versions will be supported. Please use a prior ElastiFlow release if you cannot yet upgrade to Elastic Stack 7.8.1+.
๐ ElastiFlow v4.0.0 takes advantage of X-Pack Basic features, such as the Maps, SIEM and Logs apps, as well as Index Lifecycle Management (ILM). This means that you must use at least the X-Pack Basic licensed release of the Elastic Stack. The pure Apache 2.0 licensed release of the Elastic Stack will not work without disabling many features.
