title: How to migrate indexes to a new cluster in Elasticsearch?
body: <p>For today, I have a cluster of elasticsearch containing two weeks of indexes and in few days, we will receive new machines so we will need to migrate all indexes into the new machines. For migration I have a made scenario;</p>
  
  <ul>
  <li>I will have back up of the indexes</li>
  <li>I will conenct new machines to the cluster</li>
  <li>Will wait for machines to syncronise </li>
  <li>Lastly I will shutdown all old machines.</li>
  </ul>
  
  <p>So I hope I will migrate the old cluster into new cluster. Do you think this scenario is enough or I need to add some more steps ? </p>
  
  <p>Thank you all in advance</p>
