Warning: Risky operation

*** This is a quick note only. I will write a more detailed why and what for it later.

  1. Create a new temporary field using the name you will not officially use (but can identify from the database records) with the desired reference name using Work Item Definition.
  2. Swap the reference name between current and the newly created (desired/target) ones on back end database directly
  3. Delete the temporary field (now with the old reference name)
  4. Modify the layout of ALL work item definition (for all projects) who is using this field to reference to the new reference name
  5. Delete the old work item field (witadmin deletefield)
  6. Modify the QueryItems directly on the database atble to replace the old reference name with the new one
