Hello
You can save the households in your old game to your library. Then start a new game, and you will be taken to cas. You can then open the gallery from there, and replace the random sim that is in cas with a household from your library. Then you can place that household in to the world. Then, after that you can go to the gallery by pressing the gallery button on the top right hand side of the screen and place all your old households that you saved to your library, from there into the worlds.
