Delete Instances
You cannot delete a default instance unless it is the only instance present. To delete, set another instance as default and remove the default instance flag from the existing instance.
The Delete option is not available if an instance is used in any Playbook node. In this case, the instance must be removed from the Playbook nodes to delete.
