If there is a quicker way, I have'nt found it. Luckily I only have 7000 pictures to re-tag. All your tags come in as "Imported Keyword Tags" in a list. Your categories or sub-categories are gone. Unfortunately you cannot move them back in order. You are also forced to used the Keyword Tag Names provided, such as "Color, Nature, Photography, Other, etc and cannot create any new ones or change the name. However you can create new tags under these names, but you cant move the existing categories under them as sub categories. Sorry
