Can sims move to a new neighbourhood?

Question

I got the late night expansion pack for the sims, and i'd like to move my family to the new neighbourhood that came with it.

I tried it before but they lost all their money, which i would like to avoid.

Answer 1

You cannot move sims between neighborhoods, because in Sims3 (unlike in the Sims 2) the Neighborhood is the save file*.

What you can do, is upload the family in question to the House bins, move to the new neighborhood, and then place them from the housing bin back in the world. However, this eliminates all non-household relations for the sims in question.

*Though I suppose the whole point of the World Adventures expansion is moving to foreign neighborhoods.
