Just to let you know I upgraded my SD card last weekend and it all went beautifully using your instructions. Many thanks !!! 
Just copied the old SD card to my PC, took out the old card, put the new one in and copied back.

did you mean 16GB? If so, I have a class 10 of that make and size. No issues here.
