I have a print edition with Createspace. What is the view on creating a new print edition with KDP using a new ISBN? Or should I just leave the original Print edition with CS and have them linked? If I do create a new print edition with KDP will my Createspace print edition remain or be deleted by KDP or Createspace?
If you already have a print edition at CreateSpace, there's no purpose in creating a new KDP print edition. And Amazon might be peeved. No matter whether the book is officially published by KDP-print or CS, it's sold by Amazon and will be linked to your ebook version if title and author name are identical.
CS pays a month earlier than KDP-print. Think about that. Leave things as they are.
