OpenSearch is not yet in Yum ([although it is on the roadmap for the next release](https://github.com/orgs/opensearch-project/projects/1?card_filter_query=rpm)). There are two blog posts about your subject (depending on what you’re coming from): - [Moving from open source Elasticsearch to OpenSearch · OpenSearch](https://opensearch.org/blog/technical-posts/2021/10/moving-from-opensource-elasticsearch-to-opensearch/) - [How To: Upgrade from Open Distro to OpenSearch · OpenSearch](https://opensearch.org/blog/technical-posts/2021/07/how-to-upgrade-from-opendistro-to-opensearch/)
