Motif XF extensions and XF Editor VST


Can anyone answer these questions:

Do Motif XF extensions and Motif XF Editor VST work in Cubase 6?

I just installed them in my Cubase 5 installation and love what they can do. How to i get them to work in Cubase 6? Install again?? (they are already in Cubase 5).

Thanks for any light anyone can shed on this.
