Find renamed Documents in a particular DocType in ERPNext

I have a custom DocType in my custom app that contains many entries. How do I find renamed documents in this particular DocType?

Using the new name?

Not direct but I can think of a way, did not test it though:

  1. Enable Track Changes on your DocType
  2. Write a script report to run on Version DocType, filtering both (DocType equals your DocType) AND (data contains name OR title) based on what you are looking for.
