Re: [FAQ] Why don't my expansion packs transfer between platforms?

@drewstar135 Yes, your packs will transfer from PS4 to PS5. When you download Sims 4 onto your PS5, assuming your account is the one that purchased the games and all packs, simply highlight the game on the dashboard, press the options button on your controller, then select "Manage Game Content." A list of all purchased DLC will appear and you can install them all. 

This must be done on the account that purchased the game and DLC.
