title: How to copy messages to another queue on RabbitMQ?
body: <p>Using RabbitMQ as broker, I would like to copy all the messages from one queue to another queue for test/debug purpose. What's the simplest way via RabbitMQ web management console / cli?</p>
  
  <p>P.S. Under web console for specified queue, I could only <em>Move messages</em> instead of <em>Copy messages</em> to new queue.</p>
