It saves automatically.

It doesn't save data on the Wii. You save game data by using a GameCube memory card.
if you copy the game's save data to the sd card, then put it into the different wii, and copy the save data into the wii memory from the sd card, it is possible
If the saved data is on your wii console and you play the same game on a different wii you will not have your same saved data you will have the other wii's data if it has any if you want to play a game on 2 different wii's save the data on a SD card and bring that card to the other wii to play with your saved data.
An SD card only.
You would need to transfer all your Pokemon back to your DS game, and delete the save data in the Wii Options menu (Wii Options -> Data Management -> Saves -> Wii -> My Pokemon Ranch -> Delete). However, if you delete your game save, you will lose any Pokemon left on your My Pokemon Ranch game.
When doing a system transfer between the Wii and Wii U, all data on the system is transferred. This includes save files.
its almost impossable. i tried and it just kept erasing every couple days
The save data is stored in the Wii's internal memory, but not the games themselves, except if they are Virtual Console or WiiWare games.
Rename the game save back to what it was. If you cannot remember, save the old data to your computer, then make new save game data of said game and rename your old data to the new save data's name.
It will automatically save
You don't have to save your game, it auto saves.
Go into Wii Options > Data Management and look for the Code Lyoko save game. If you move the save file to an SD card it will allow you to create a new game without loosing your old game. (or you could just delete the save file if you don't want it anymore) Unfortunately, it doesn't look like you can have multiple active save files without doing this.
