How often do you plan on updating software at the dealership? Since you're out of warranty, I doubt this would be likely anytime soon. While the dealer may have trouble, there are always independents that can perform "per module" updates if needed via autologic.
I wouldn't worry about it, or simply have the vehicle updated before converting to the CIC if you're looking for peace of mind.
Give me a call if you'd like to discuss further.
