Hmm, I figured this would only bring the "settings" over, as in the preferences of the connection, not friend codes and the like.
Dammit, I knew I should have looked further into that option.
Assumption is still the mother of all screw-ups...
EDIT: I feel like a colossal sack of stupid right about now. The transfer took exactly 3 minutes from start to finish as I moved the config from one DS to the next and back again.
Sigh. Live and learn...
At least I won't make this mistake again.
