I have been unable to find a document for this, but people must be doing it all the time.

I currently have a kobo aura, and want to transfer the books to a kobo clara.
I would like them to keep things like finished/unread, last read, date of addition to library and progress of the book I am reading.

I have tried sending a finished book to aura, but it comes up as unread.

Once this is completed, I want to do the same from a sony to the aura.

If anyone can point me to a step by step guide it would be appreciated.
