GameStop may be offering a trade-in bonus on your Wii right now, but you may not want to rush to trade up for a shiny new Wii U just yet.
Wii owners will be able to transfer their data—including saved games and purchased Wii Shop titles—from their Wii to their new Wii U, but there's a catch. Both consoles, old and new, will need to be connected at the same time to do it.
Gimme Gimme Games reports that according to Nintendo:
Wii U owners can wirelessly transfer content such as Miis, and WiiWare and Virtual Console games to their Wii U systems. Both systems will need to be connected to the Internet and the Wii U will need an SD card to facilitate the transfer. The process is very similar to transferring content from Nintendo DS to Nintendo 3DS or from Nintendo 3DS to Nintendo 3DS XL
While it's great news that users can easily transfer their data, the timing will no doubt leave something to be desired for many console owners looking to upgrade this November.
