title: Do you need to delete Elasticsearch aliases?
body: <p>Can't seem to find a simple yes or no answer to this question.</p>
  
  <p>When you have an index with one or more aliases can you just delete the index without any negative side effects? Will deleting the index also delete the aliases? Should you remove all aliases first before deleting an index?</p>
  
  <p>What is considered best practice?</p>
