title: How to export a container in Singularity
body: <p>I would like to move an already built container from one machine to another. What is the proper way to migrate the container from one environment to another?</p>
  
  <p>I can find <a href="https://singularity.lbl.gov/docs-export" rel="nofollow noreferrer">here</a> the image.export command, but this is for an older version of the software. I am using version 3.5.2. </p>
  
  <p>The container I wish to export is a <code>--sandbox</code> container. Is something like that possible?</p>
