I just installed the PS5 upgrade with my PS4 disc version and this is how it went for me.
I didn’t have the game installed to begin with so when I inserted the game disc, it asked for the data disc to start installation of PS4 version.
I checked the icons (3 dots) to see if there’s an option to go straight to PS5 upgrade but didn’t see anything.
Then I noticed a promo on top right where it says PS5 upgrade free so clicked it and it asked me to confirm the free purchase and reminded me that I need the game disc to play.
After that, it started to download the PS5 version.
But since I already inserted the data disc, it started the PS4 partial install which I just deleted manually. I reinserted the game disc while PS5 version is downloading and just went from there.
