title: How to upload IPA file to new testflight?
body: <p>I have my app first version released in app store. Currently I'm working on the second version, earlier i was used Test flight for importing IPA file for testers. But for now They are shutdown and moved into iTunes Store. So my doubts regarding new methods are:</p>
  
  <ol>
  <li>How to upload test builds (IPA)   </li>
  <li>I need to import many test builds to attain stable one. Is that possible here?<br>
  like as test flight     </li>
  <li>Shall I need to change version number of test build each and every time?</li>
  <li>Since i have already released version 1, Is it possible to use same name for 
  test build?</li>
  </ol>
