# UpdateKxClusterDatabases
<a name="API_UpdateKxClusterDatabases"></a>

Updates the databases mounted on a kdb cluster, which includes the `changesetId` and all the dbPaths to be cached. This API does not allow you to change a database name or add a database if you created a cluster without one. 

Using this API you can point a cluster to a different changeset and modify a list of partitions being cached.
