title: Elasticsearch - importing data from another data folder
body: <p>I copied a data folder from another ES instance into a new ES install (same version). After starting my new Elasticsearch, it does not recognize the new data.</p>
  
  <p>I tried renaming the cluster.name in the YML config file, but no success.</p>
  
  <p>Any ideas?</p>
  
  <p>Thank you.</p>
