not at all - you are correct. The presentation at the last NANOG said that 
if you are in a routing domain with an existing 2 byte AS number then you 
need to change _nothing_. Of course, after a few years, you may come to the 
conclusion that AS23456 has launched a nefarious plot and is popping up all 
over the routing world, but you will still need to change _nothing_.
