Ps4 – Will data from one PSN transfer to another

At present, there is no way to transfer trophy information from one account to another (still). Logically, it doesn't make sense for trophies to be transferable. This person earned this proof that they did something - what meaning would these have if you could transfer them to someone else? This would certainly allow for a shim to act as a psn id change, but that would be the wrong solution to the problem.

Some few saves and other data can be copied over but often, like trophies, these are usually non-transferable as well. To determine which data can be transferred, you would have to go through each and try it. The logic behind this is probably the same as trophies and possibly even related to how much easier it is to cheat trophies with someone else's saves.

You still cannot change your psn id and there are no practical workarounds. All you can do is start over. Sony might have reasons, but it is a hotly discussed feature that exists on the Japanese PSN. There has never been an outright denial of the future possibility (only statements that implementing this feature is "very technically complex").

On PS4 you can sort of get around this by changing your real name, but that doesn't allow numbers or special characters and will not help you on PS3.

No, you can't change the account your PSN 'subscription' is attached to, however if you only have the One PS4 then you can set this PS4 as your primary system and any account on there will have access to PSN as if it was subscribed.

So simply do this:

1. From the existing PSN subscribed account make sure this PS4 is your primary PS4
2. Create another account and use it normally
3. Once your PSN expires on the 'old' account simply apply it on the new one instead.
