This may be something very old and boring but it was a new discovery for me. This lastest discovery is important to me because the 1st world I created was getting over-crowded. I found out how to move surplus Sims to my newly created world and I am very happy and proud of me. (I had another breakthrough but am too embarassed to admit that one because my daughter said she knew that without playing the game.) Maybe I missed something in the tutorial or the instructions.

You do it by saving the families, entering the saved families in the new 'hood and then removing the families from the old?
I think that this "move" is not perfect, meaning that moved Sims forget the relationships they had in the older neighborhood.
Frex, if A1 from family A and B1 from family B are friends, and both A and B families move from 'hood x to 'hood y, A1 and B1 will become strangers - I think.
