I've never used the plugin, but there's one for Sigil that will convert an epub2 into an epub3. Maybe it's available for the Calibre editor?

I don't know the specifics but thought it was merely a change of a few lines at the top of the file and changing its extension from html to xhtml (for all html files in the epub). But I'm sure there's more than that.
