I'm getting a PS5 and it will primarily be used on my main TV, but I'm also keeping my PS4 to use in a guest room for TV/movies/games. There will be times when my main TV will be occupied by my husband as he will play video games, watch TV, etc. I understand that certain games will have free upgrades to PS5, while others will basically be different SKUs. Would it make sense to buy PS4 games that have PS5 upgrades so that I can transfer the game/save data instead of unplugging and plugging the PS5 console and lugging it around the house? Is that even a feature that I can do with a PS4 and a PS5?
