Converting from KFX to KFX actually converts from KFX to EPUB, runs that through the calibre conversion pipeline, and then converts back to KFX. Because KFX is not based on HTML, irreversible changes occur during conversion. In addition calibre can make various alterations, such as downsizing images and regenerating the table of contents.

If DRM removal fails you will be left with a book in KFX-ZIP format instead of KFX format. That is the easiest way to tell if something went wrong.
You can also view the book after import to verify that it is readable. See "Viewing books in KFX format" in the
KFX Input documentation for ways to do that.
