title: How do you move a SharePoint 2010 DocumentSet from one list to another?
body: <p>I've tried many variations.</p>
  
  <ol>
  <li>Send To Library - That creates a Zipped file in the Drop Off Library, then it doesn't route via the rules in Content Organizer</li>
  <li>API - I've tried to do an Export, Import, but always receive the same error.  This is per this MSDN documentation:  <a href="http://msdn.microsoft.com/en-us/library/microsoft.office.documentmanagement.documentsets.documentset.create.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/microsoft.office.documentmanagement.documentsets.documentset.create.aspx</a></li>
  </ol>
  
  <p>Sample snippet:</p>
  
  <p>byte[] exportedFile = set.Export();</p>
  
  <p>DocumentSet.Import(exportedFile, DocSetNameToCreate, targetFolder, dsCt.Id, properties, web.CurrentUser);</p>
  
  <p>Error Received:</p>
  
  <p><strong>DocID: Site prefix not set</strong>.</p>
