The rumors are no longer rumors. Createspace is shutting down and moving all it’s titles – your titles, perhaps – to KDP Print.
When is this happening? “in a few weeks.”
Can I move my books to KDP Books sooner? Yes you can, at this link: https://kdp.amazon.com/createspace-transfer. Or so they say, in theory. I tried today and it didn’t work. It opened my account (Step 1), It verified my titles (Step 2), but a no go on the ‘Start the move’ (Step 3). I’m guess they are inundated with people trying to move their books.
Don’t worry. They’ll move your books for you eventually. Maybe I’ll just let them do it.
If you have other questions, you can go to this CS to KDP FAQ page and probably get an answer.
Here’s another link to a post by Amy Collins on The Book Designer site.
Best of luck!
