Now at < 72hrs, called again. They confirmed my upgrade.

The point of my post is as follows:

The new 767 two class service only has 30 premium (Business) class seats. Evidently, I gather from other post, 2 seats are reserved for pilot rest and 2 seats are block due to the cabin configuration. So there are 26 seats available. This is a large reduction compared to premium (First/Business) seats on the 777.

I think it is more difficult to up grade on the two class 767.
