About Elasticsearch 6
Elasticsearch 6 reached end of life over 4 years ago on February 10, 2022. It no longer receives security patches, bug fixes, or any form of official support. Running this version in production exposes your systems to unpatched vulnerabilities and growing incompatibility with modern libraries and tooling.
The recommended upgrade path is to Elasticsearch 9.3. Since Elasticsearch 6 is 6 major versions behind, consider a staged upgrade through intermediate versions to catch breaking changes incrementally rather than all at once. Review the release notes for each intervening major version to identify API changes, deprecated features, and removed functionality that may affect your codebase.
