Thanks for the info Grant. If the only difference is in the PDC device tables then the transition should work with no problem.

The reason we are going with a rp2430 -> rp2470 rather than starting with an rp2470 is that upgrade will coincide with the system moving from development into production. This move is dependent on guesses we've made about business conditions in a few months time (which might be wrong).
