Witcher 3 plays from one ps4 to another?

When the new game "The Witcher 4 - Wild Hunt" went on sale at that time, I immediately fell in love with it and bought it a short time later, including both DLCs. Since I did not have my own Ps4 at the time, I was allowed to install the game with a friend. Now I finally got my own console a few days ago. The same ps4 that also has said girlfriend. Since she said it was easy to transfer the score, she explained it to me quite simply. I simply added her account on my console, then downloaded the game. Since the game told me it needed some time to download the existing files, I did not think anything of it and was happy that it was not as complicated as I thought.

Today I looked and noticed that it either deleted my game or simply did not take over, because I would have to start all over again. And I must say, as much as I love the game, I do not want to reconstruct the countless hours of play.

Does anyone have any (please) an idea how I can get my memory level again? I've been searching online for hours, with all sorts of terms and all the trimmings, am slowly finishing with my Latin and just before howling.

You have to upload the score on the 1st console to the online store, if this is not done automatically. Then you download it on the 2nd console from there. Alternatively, a USB stick can be used.

Simply copy the memory data from the console your friend with a USB stick and plug in and paste on your console.
