How to Copy Mii Data to Another Wii

Select and launch the Mii channel from your Wii's main menu using the Wii remote.

Wiggle your Wii remote once the main plaza screen loads. This will cause several gray icons to appear on the left and right sides of the screen. Choose and click on "Transfer Mii," which is located on the right-hand side, and is the second button from the top (labeled with an image of a Wii remote).

Select the Wii remote you want to load your Mii onto. The remote you're operating will be number one. Other active remotes will be indicated by the number of tiny blue lights that are lit on the bottom of the remote's button face.

Click "yes" if prompted to format the Wii remote.

Grab and drag a Mii from the plaza by pressing the "A" and "B" buttons at the same time. Drag the Mii into one of the 10 green circles at the top of the screen. Repeat with other Miis if you want, filling as many of the circles as you'd like, and taking up to 10.

Click "Save &quit."

Bring your Wii remote to where your friend's Wii is set up. Once it is activated, check the number of blue lights to see which number remote the new system counts it as.

Repeat steps 1 through 3.

Drag your Miis from the green circles at the top of the page down into the plaza using the "A" and "B" buttons.

Select "Save &quit," then close the Mii channel to return to the Wii home screen. Your Miis will now be included as an option in any games that use Mii avatars.
