Kibana OSS stores its visualizations and dashboards in one or more indexes (`.kibana*`) on the Elasticsearch OSS cluster. As such, the most important step is to leave those indexes intact as you migrate from Elasticsearch OSS to OpenSearch.
In general, settings with `elasticsearch` in their names map to `opensearch` (for example, `elasticsearch.shardTimeout` and `opensearch.shardTimeout`) and settings with `kibana` in their names map to `opensearchDashboards` (for example, `kibana.defaultAppId` and `opensearchDashboards.defaultAppId`). Most other settings use the same names.
For a full list of OpenSearch Dashboards settings, see [opensearch_dashboards.yml](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/config/opensearch_dashboards.yml){:target='\_blank'}.
1. If your OpenSearch cluster uses the Security plugin, preserve and modify the default settings in `opensearch_dashboards.yml`, particularly `opensearch.username` and `opensearch.password`.
If you disabled the Security plugin on your OpenSearch cluster, remove or comment out all `opensearch_security` settings. Then run `rm -rf plugins/security-dashboards/` to remove the Security plugin.
