title: Amazon DynamoDB - modify indexes - copy data from table to table
body: <p>I must change the Key Schema of a DynamoDB table. In <a href="http://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_UpdateTable.html" rel="nofollow">in the official documentation</a> it is clearly written that:</p>
  
  <blockquote>
    <p>You cannot add, modify or delete indexes using UpdateTable. Indexes can only be defined at table creation time.</p>
  </blockquote>
  
  <p>I was thinking of creating a new table (with the correct indexes) and migrating the data from the existing to the new one. Is there any tool that I can use for that? I have used <a href="https://github.com/edasque/DynamoDBtoCSV" rel="nofollow">DynamoDBtoCSV</a> but it only supports export.</p>
