I am thinking about buying a PlayStation 4. I have had a PS3 for years and I setup my PSN account on this system. If I buy a PS4, will I have to start all over again or can I use the same account on the PS4 that I used on the PS3?
Yes, all PlayStation gaming systems share the same online network and user account system. There are some limitations, such as not being able to communicate with PS4 players from the PS3. If this doesn’t bother you then you are all good.
Anyone who had a PS3 and created an account for PSN on this system, can use the same username and password to log into PSN on the PS4 without needing to do anything. It will all work seamlessly. You can also log into the Vita and into the PS store on PC and mobile using the same PSN account. Unlike Nintendo, they did things properly…although that could be argued.
For some reason some people who try to do so get the WS-44949-0 error message followed by “this account cannot be logged in to this ps4”
