Purchased a SR102 to replace my SR101, do I need to do anything?

Hi
I purchased a brand new SR102-Z from eBay which was still sealed in its packaging. I already own a SR101 so do I still need to extract my username and password from the SR101 to be able to use the SR102?
If so am I to follow the instructions here http://www.skyuser.co.uk/forum/extra...tml#post429128
