Question: how to transfer wii mii data to another wii?
Answer: A Mii that resides on the Wii Remote is just a copy of the Mii that resides on the Wii console. To transfer one or more Miis to your Wii Remote, click the Transfer Mii button; when the screen showing the connected Wii Remotes appears, click the Wii Remote that you want to transfer the Miis to.
