title: Start a workflow on items that already exist
body: <p>I have added a workflow to a SharePoint(2007) calendar.  The workflow copies information from Column A to Column B if Column A is not equal to Column B.  I set this workflow to start when an item is created or modified.  However, I would also like to start this workflow on all items that already exist in this calendar.</p>
  
  <p>Is there a way I can do a mass start and run the workflow for all the items that already exist?</p>
  
  <p>EDIT:  Let me clarify my question a little more.  I would like to run the workflow one time on the 200-300 items that have already been created.  I don't need to traverse the items everytime a new item is added.  Just one time to compare/copy Column A to Column B for all the existing items</p>
