If you want to deactivate your PSN account on another PS3, there are a few things you need to do. First, make sure that the other PS3 is turned off and not in standby mode. Then, go to the “Settings” menu on your PS3 and select “Account Management.” From here, you’ll need to enter your password to log in. Once you’re logged in, select “Deactivate Account” from the menu on the left. You’ll then be asked to confirm your decision by selecting “Yes” or “No.” If you choose “No,” your account will remain active on the other PS3. If you choose “Yes,” your account will be deactivated on the other PS3 and all of its data will be deleted. ..
