If you no longer intend to use your PS4, perhaps because you have upgraded to a PS5 or are selling it, you should deactivate the PS4 so that it is no longer associated with your account. This will allow you to set up another console using the same account.
It’s important to designate the PS4 console you currently own and use as your primary device, because this is where pre-ordered games are automatically installed. Other players can also share games on your main console, and if you’re a PlayStation Plus subscriber, you can use the main console for multiplayer games. Sony allows you to activate one PS5 and one PS4 at a time.
How to deactivate your main PS4
You can deactivate your PS4 from the console itself, which you should before selling, giving away or disposing of it. Even if you forget to turn off the console and no longer physically own it, that’s fine; you can also deactivate your PS4 from the Sony website.
