I will soon be getting a new bike which has 10 speed Shimano RS 10 wheels but i am swapping the wheels for a set of Mavic Open Pro wheels with Ultegra Hubs but the cassette on the Open Pro wheels is 9 Speed.
So is it just a matter of swapping over the rear wheel cassettes?

    You will probably need an extra spacer behind the cassette. Most Mavic hubs need one spacer because the cassette is Shimano, and one if 10 speed. That is, if 10 speed Shimano, you need two. That's how it is with my Mavics at least. The extra spacer comes with the wheels.

    Have an experiment re spacers - I have ever only used one spacer with mavic wheels (everything from Aksiums, Kyseriums through to carbon Cosmic things) I had an issue very kindly solved on here with an Aksium that needed two spacers - weird, weird.

    One thick and one thin spacer.

    Otherwise its a straight swap. 40Nm for the lock ring.

    Is it not the hub that determines if you need spacers or not?

    Correct.
    - the hub and cassette.

    You need a spacer to fit a 10sp 105, Ultagra or DA cassette (not Tiagra, not SRAM 10sp) to a 8/9/10sp hub
    You don't need it for a 8sp or 9sp cassette

    Someone above talks about 2 spacers - on Mavic wheels. You need a spacer to fit a Shimano or SRAM cassette to a Mavic M10 hub, then you'll need the other one for a Shimano 10sp cassette as above.

    The OP here is moving a 10sp cassette from a set of RS10 wheels, with a 8/9/10sp hub, to another set currently fitted with a 9sp cassette on an Ultegra hub (Ultegra 6600 was 10sp-only, wouldn't take a 9sp cassette, so this must be an Ultegra model which is also 8/9/10sp-fit)
    - on removing the 10sp cassette from the RS10 wheels, then if it's 105, Ultegra or DA you should find a thin (1mm) spacer behind it
    - if it's Tiagra or SRAM, there won't be
    - on removing the 9sp cassette from the Ultegra wheel, should be no spacer
    - just move the 10sp cassette with its spacer, if it has one, to it
