You may experience the widgets in the sidebars becoming disorganized. The solution there is easy; simply moving them from one sidebar to another to put them back in place.
Post and page images should remain intact, but things like your branding image, backgrounds, etc may need to be reinstalled.
Your older custom CSS will likely need to be updated. So you may experience some changes.
I've done these conversions on fairly complex sites before and it's never taken me more than a few hours. Framework has so much that's drag & drop that it's incredibly easy to set up. Also, there's a Store with tons of free resources as well as premium plugins, sections and themes to help make your transition as easy as possible.
