Mine popped up an error at fifteen percent complete to Wii U and I had to pull the plug on the machine to reset. I relaunched the transfer channel and it picked up right where it left off without issue. I noted before launching the Transfer channel again after restart that a lot of channels were present, so it does copy things individually.
The initial write to SD from Wii is ver speedy; the copy from SD to Wii U was the slow part.
After that experience I'd say the only thing you should worry about is the power going out on the initial Wii to SD write operation.
