title: Android Emulator: How to Copy an Emulator / AVD?
body: <p>I am currently making an upgrade of an existing app that's already on the Google App store (aka Google Play).  I want to test that the data conversions go smoothly when customers upgrade.</p>
  
  <p>I have an AVD with the old version of the app installed.  The usual thing would be to run the new version on this app and see if it works.  But the problem is that after doing this, that particular AVD is no longer mimicking that old state.</p>
  
  <p>I'd like to make copies of this AVD/Emulator (yeah, the whole thing!) so that I can make repeated tests.</p>
  
  <p>This seems like something that would happen often, but I can't find any references to this situation.  Or am I missing something obvious (I hope!)?</p>
