Wii-U Network Extremely Slow

[SvennoJ]

Updating took a little over an hour, then download the You Tube app, update Nintendoland, update Mario, welcome to the HD generation ugh. The 2nd update has not turned up yet. It says there is one in the message center but when I check for an update it says up to date, so confused...

Is there a way to get your Miis from the Wii to the WiiU without wiping the Wii in the process? System transfer should do it but that wipes the Wii according to the instructions. Transferring via Wii remote doesn't seem supported as the import feature is missing from the WiiU's Wii menu.
