title: Copy files from AWS S3 to Azure storage archive tier
body: <p>I'm trying to copy files from AWS S3 to Azure storage archive access tier directly. Using <code>azcopy</code> I can copy the files from S3 to Azure but when using <code>--block-blob-tier Archive</code> flag I hit the error:</p>
  
  <pre><code>failed to parse user input due to error: blob-tier is not supported while copying from sevice to service
  </code></pre>
  
  <p>The only way around this I can find is to either download the files locally and then upload to Azure or change the access tier once uploaded. The first is the better solution as with the second it would be twice the cost (pay for the write operation when changing tier). Does anyone have another option or know why <code>azcopy</code> doesn't support this?</p>
