title: Accurev: change package merge required
body: <p>I've got a workspace backed to my collaboration stream (CS), the CS has a parent stream (Parent).</p>
  
  <p>In my workspace I changed a file with version Parent/1 and then promoted it to the collaboration stream some times. Its version became CS/2. </p>
  
  <p>Then I got an update from the Parent and found that I don't need to keep my changes in that file and purged it on the CS. Its version became "CS/2*" on the CS and "Parent/2" in my workspace.</p>
  
  <p>Now I'm trying to make some changes in the file in my workspace and promote it to the CS again, but I've got the message "change package merge required" for the file.</p>
  
  <p>If I understand correctly, it can't be promoted due to the file version in my workspace is not derived from CS/2. How can I resolve the issue and promote new changes to the CS?</p>
  
  <p>P.S. Moreover I have a pack of such files - about 70 files. How can I resolve the problem for the whole pack of files?</p>
