title: How do I rename a mongodb replica set?
body: <p>I started up a few MongoDB replica sets with the default configuration and added them to <a href="https://www.mongodb.com/cloud/" rel="noreferrer">Cloud Manager</a>, but since the default replica set name is "rs0", they're hard to tell apart in the UI. Is there a way to change the name of a replica set, preferably without having to drop and re-import all of the data in the cluster?</p>
  
  <p>I've tried using <code>rs.reconfig</code> (<a href="https://docs.mongodb.org/manual/reference/method/rs.reconfig/" rel="noreferrer">link</a>) but it doesn't allow you to change the replica set name.</p>
