It can be very tricky or difficult sometimes. But unfortunately, you cannot move out a single sim out of the update. In The Sims 4, the Manage Households option gives you everything you need to customize Sims that have either already moved in, or have yet to move in, in either World.
You may have noticed that you can't move Sims out using the phone like you could in The Sims 3. You may expand your house by increasing the size of rooms, building new ones, or creating another floor. The Sims 4 offers really wide opportunities for enlarging existing rooms without demolishing them. The house you build or purchase at the beginning may be just right for you for a long time, but sooner or later you will need to expand it.
