Your existing cover will be fine, but it’ll need to be rebuilt using whatever dimensions KDP/Ingram provide to suit your new spine width.  Our fee to complete this is £100 GBP.  For that fee, you will have your cover restructured using the new templates. You’ll be provided with new PDF files and new marketing images with the correct spine width.  We will move all of your existing files into an archive on your private Dropbox so that you still have them to refer to, and will provide you with a new completion email with updated links to files.  Please note: If you’re making significant changes to your manuscript, you will also need new ISBNs as this will be classed as a new revision.  The only time you won’t need a new ISBN is if the content only changes briefly (typos being fixed, or you’ve altered the interior formatting, and this has affected the page count).
