New wheels - new cassette - new chain

In the process of getting some Mavic Ksyrium to upgrade from Mavic Aksium. However, I would like to keep the cassette on the Aksium, so I can change over to use as winter wheels.

The current Aksium wheels have only done just shy of 200miles.

Would I need to get the exact some cassette (Shimano CS 5700 12-25T), or what options do I have? Also, will I need a new chain too?

Please excuse my lack of knowledge :oops:
