Also got a feeling it's going to be one of those cross save situations which requires you to a) reinstall the ps4 version, b) update the ps4 version, c) go into the ps4 game and upload your save file to the cloud, d) exit and delete the ps4 version, e) install the new ps5 version, f) launch the ps5 version and then download your save file from the cloud within the game.
