When I git my BK9 I wanted to save some Styles used on my G1000. Plus some Styles I had in libraries of old Roland Styles. After time I found out the Styles included with the BK9 just sounded better, More defination to the instruments etc. So I've found myself slowly replacng the old ones I can identify with newer ones. The key to any of these is Editing !
I do tons of editing to any style and then after awhile I do more wondering what I was thinking during the first edit. In the BK9 I haven't found any gaps in the tradional music Styles. There's always something that will work. Not so much in the dedicated song styles so you have to adapt and "make it your own version" I guess what I'm saying is throughly investigate your new keyboard first. Have fun.
