Changing a cluster's name is quick and easy! From the cluster dashboard, simply navigate to the Settings link under the Manage header:
Under the "Edit Cluster Name" form, enter the new name for the cluster, and click on "Save."
Changing your cluster's name will not result in downtime or loss of data. It will also not change the cluster's URL. If the name is already taken by an active cluster in your account, you will receive an error.
