 ## Migrating OpenSearch Dashboards clusters
 
 If OpenSearch Dashboards is being run in a cluster, migrations will be coordinated so that they only run on one OpenSearch Dashboards instance at a time. This is done in a fairly rudimentary way. Let's say we have two OpenSearch Dashboards instances, opensearch-dashboards-1 and opensearch-dashboards-2.
 
 * opensearch-dashboards-1 and opensearch-dashboards-2 both start simultaneously and detect that the index requires migration
-* opensearch-dashboards-1 begins the migration and creates index `.opensearch-dashboards_4`
-* opensearch-dashboards-2 tries to begin the migration, but fails with the error `.opensearch-dashboards_4 already exists`
+* opensearch-dashboards-1 begins the migration and creates index `.opensearch_dashboards_4`
+* opensearch-dashboards-2 tries to begin the migration, but fails with the error `.opensearch_dashboards_4 already exists`
 * opensearch-dashboards-2 logs that it failed to create the migration index, and instead begins polling
-  * Every few seconds, opensearch-dashboards-2 instance checks the `.opensearch-dashboards` index to see if it is done migrating
-  * Once `.opensearch-dashboards` is determined to be up to date, the opensearch-dashboards-2 instance continues booting
+  * Every few seconds, opensearch-dashboards-2 instance checks the `.opensearch_dashboards` index to see if it is done migrating
+  * Once `.opensearch_dashboards` is determined to be up to date, the opensearch-dashboards-2 instance continues booting
 
-In this example, if the `.opensearch-dashboards_4` index existed prior to OpenSearch Dashboards booting, the entire migration process will fail, as all OpenSearch Dashboards instances will assume another instance is migrating to the `.opensearch-dashboards_4` index. This problem is only fixable by deleting the `.opensearch-dashboards_4` index.

 - `MY_USAGE_TYPE` can be any string. It usually matches the plugin name. As a safety mechanism, we double check there are no duplicates at the moment of registering the collector.
 - The `fetch` method needs to support multiple contexts in which it is called. For example, when stats are pulled from a OpenSearch Dashboards Metricbeat module, the Beat calls OpenSearch Dashboards's stats API to invoke usage collection.
-In this case, the `fetch` method is called as a result of an HTTP API request and `callCluster` wraps `callWithRequest` or `opensearchClient` wraps `asCurrentUser`, where the request headers are expected to have read privilege on the entire `.opensearch-dashboards' index. 
+In this case, the `fetch` method is called as a result of an HTTP API request and `callCluster` wraps `callWithRequest` or `opensearchClient` wraps `asCurrentUser`, where the request headers are expected to have read privilege on the entire `.opensearch_dashboards' index. 
 
 Note: there will be many cases where you won't need to use the `callCluster` (or `opensearchClient`) function that gets passed in to your `fetch` method at all. Your feature might have an accumulating value in server memory, or read something from the OS, or use other clients like a custom SavedObjects client. In that case it's up to the plugin to initialize those clients like the example below:
