Transferring saved sims data to another playstation

Hello

Normally, you can transfer data from a PS4 to another using a cloud or an USB key. In the parameter, but you can also transfer directly datas.

For transfering data directly : https://manuals.playstation.net/document/en/ps4/settings/transfer.html 

For transfering data indirectly : store  and upload from cloud  or transfer from USB key 

For some games, the datas are set for your account, and can refuse some achievements if you use them with another user.
