2009 DB9 electronics and wire swap

[Francis2002]

I have a 2009 db9 and am in the process of replacing all computers and wiring taken on a wrecked 2009 db9.


Once all is transferred will it start or will the computers need reprogramming to recognize the engine as it not the same serial number?


If so, how many of the computers or reprogramming is needed to mate with the engine, transmission and differential, possibly other components as suspensions?


Thanks for your input.
