Erm, what. 

Please explain how the fact that you cannot squeeze a 40G partition into a 20G 
one, something I would have thought obvious, leads you to the conclusion that 
the destination has to be bigger than the source. 

All this proves is 40 > 20 : hardly ground a breaking discovery...

For the record the destination has to be THE SAME size or bigger. There is no 
requirement (I am aware of) that it must be at least a byte bigger....
