Will I need to redownload content on the target Wii U after the transfer has been completed?

During the system transfer process, any content that was downloaded on the source Wii U will be added to Download Manager on the target Wii U. This means it will be queued to download automatically after the transfer has been completed. The maximum number of queued downloads is 64. Any excess downloads will need to be downloaded by adding them from the Nintendo eShop.
