 #### Restoring OpenSearch Dashboards data
 
-Data in OpenSearch Dashboards (saved searches, visualizations, dashboards, etc) is stored in the index `.opensearch_dashboards_x`. To restore that data you first need to delete the index and then do a restore.
+Data in OpenSearch Dashboards (saved searches, visualizations, dashboards, etc) is stored in the indices pointed to by the alias `.kibana`. To restore that data you first need to delete the index and then do a restore.
 
-This will overwrite anything in the current `.opensearch_dashboards_x` index. If there is something new that should be saved, then [export](https://www.elastic.co/guide/en/kibana/7.10/managing-saved-objects.html#_export) the saved objects and [import](https://www.elastic.co/guide/en/kibana/7.10/managing-saved-objects.html#_import) them after the restore.

 Make sure that the index you want to restore also exists on the snapshot. (May be an issue if you are using an old snapshot)
 
 ```bash
-curl -kL -u "${user}:${password}" -X GET "${os_url}/_snapshot/${snapshot_repo}/${snapshot_name}?pretty" | jq '.snapshots[].indices' | grep .opensearch_dashboards
+curl -kL -u "${user}:${password}" -X GET "${os_url}/_snapshot/${snapshot_repo}/${snapshot_name}?pretty" | jq '.snapshots[].indices' | grep .kibana
 ```
 
 > [!NOTE]
-> If you visit the `"<os_url>/app/dashboards"` page in the OpenSearch GUI after deleting the index and before restoring the index, another empty index `.opensearch_dashboards` will be created. You need to delete this manually, which can be done with:
