title: Converting Archetype Content to Folderish
body: <p>I have an archetype content type that previously was not folderish.  Now I have set it as folderish.  What attribute or properties need to be changed so that any data created before can be migrated? </p>
  
  <p>I have read the following documents:</p>
  
  <p><a href="http://collective-docs.readthedocs.org/en/latest/components/genericsetup.html#upgrade-steps" rel="nofollow">Generic Setup Upgrade Steps</a></p>
  
  <p><a href="http://collective-docs.readthedocs.org/en/latest/content/archetypes/converting-content-types.html" rel="nofollow">Converting one Content Type into another</a></p>
  
  <p>I followed the above tutorial on upgrade steps but I do not know which attribute or properties to change.</p>
