Conversion of mobi files to azw2 file format

It is not possible to convert mobi to azw2, because .azw2 files are not ebooks, but active content apps for Kindle. You will have to convert mobi to azw2 if you want to create an ebook compatible with Amazon Kindle, although Kindle should be be able to handle MOBI ebooks just fine.
