title: How to fetch & update custom aspect property in 5.1.1
body: <p>We have created custom property using custom content model.We need to fetch below information from the custom content model. </p>
  
  <p>1)How can we fetch all Node Ref's which is having the cc:status property?   </p>
  
  <p>2)Lets say I will create new namespace[<a href="http://www.XXXX.co/model/copy-status/1.0]" rel="nofollow noreferrer">http://www.XXXX.co/model/copy-status/1.0]</a> and new aspect name[cc:new-digeststatus].How can we update all old properties of cc:status to the different aspect name[cc:new-digeststatus] with different namespace? </p>
  
  <pre><code>&lt;namespaces&gt; 
  &lt;namespace uri="http://www.custom.co/model/custom-status/1.0" prefix="cc"/&gt; 
  &lt;/namespaces&gt; 
  
  &lt;aspects&gt; 
  &lt;aspect name="cc:digeststatus"&gt; 
  &lt;title&gt;Status&lt;/title&gt; 
  &lt;parent/&gt; 
  &lt;properties&gt; 
  &lt;property name="cc:status"&gt; 
  &lt;title&gt;status&lt;/title&gt; 
  &lt;type&gt;d:text&lt;/type&gt; 
  &lt;/property&gt; 
  &lt;/properties&gt; 
  &lt;/aspect&gt; 
  &lt;/aspects&gt;
