title: MongoDB Java driver questions
body: <p>We are looking to upgrade our MongoDB from version 3.0.6 (with Java driver 3.0.4) to version 3.2.12.  (I know version 3.4.x is available, but I understand you can't go directly from 3.0.x to 3.4.x if you need to migrate data.)  A couple questions about the Java driver:</p>
  
  <ul>
  <li>Is Java driver 3.2.2 the right version that matches server 3.2.12?</li>
  <li>Is it supported for a newer Java driver version to communicate with an older server version?  In this case, it would be Java driver 3.2.2 talking to an older 3.0.6 server.  I compiled our client code with Java driver 3.2.2 today and saw no differences in the compiler output, so they seem compatible -- though this may not be supported in any case.</li>
  <li>Are there any issues with using Java driver 3.0.4 to talk to server 3.2.12?</li>
  </ul>
