Copy appsets?

Last week, Steinberg launched Nuendo7.

Since I've been working with Nuendo6 on my MC Pro, I'd like to copy my entire MC-Pro-soft-keys-structure from the appset "Nuendo6" to the appset "Nuendo7" , but when I choose appset "Nuendo6" and copy+paste it into the appset "Nuendo7" my MC Pro says something like :"your paste-location is the same as your copy-location, nothing will be done"........is this a bug, or am I overlooking something?
How can I simply copy and paste my soft keys from Nuendo6 to Nuendo7?

Thanks! Niek/ Amsterdam.
