<p>Migration targets have been change, some statistics of interest from a <a href="http://meta.stackexchange.com/questions/118685/should-some-communities-have-more-than-4-migration-targets">related Meta.SO question</a>.</p>

<blockquote>
  <p>In the last 90 days (data gathered on January 15th 2012), Server Fault
  has had 597 question migrated away from it:</p>
  
  <ul>
  <li>Super User†: 332, 12% rejected</li>
  <li>Stack Overflow†: 74, 10% rejected</li>
  <li>Unix &amp; Linux: 47, 14% rejected</li>
  <li>DBA: 35, 8% rejected</li>
  <li>Apple: 32, 0% rejected</li>
  <li>Web Masters†: 27, 7% rejected</li>
  <li>Ubuntu: 20, 5% rejected</li>
  <li>Security: 18, 0% rejected</li>
  <li>SharePoint: 7, -- not enough data</li>
  <li>Programmers: 2, -- not enough data</li>
  <li>WordPress, Web Apps, Project Management, Electronics: 1 each, -- not enough data</li>
  </ul>
  
  <p><sub>†Existing migration targets at time of writing.</sub></p>
  
  <p>Tossing out the rejections, this would mean that approximately <strong>154
  legitimate migrations</strong> were not covered by our migration targets
  (compared to  384 that were).</p>
  
  <p>Note, there's about a 10% chance the migration is rejected (closed on
  the destination site); this is important.</p>
