Can I copy D3 cd ps4 version to PS5?

I have the PS4 cd version of D3
Currently playing it on PS5 using the disc,
but just curious if it is possible
to copy the CD onto the PS5’s storage?
Planning on installing a 2 TB ssd…

Any constructive advice appreciated.

Short answer is sorry, but the only way to legally play a PlayStation game without the disc is to purchase the game digitally.

Long answer is the game is pretty much copied from the disc onto the console’s hard drive. The only thing the disc in needed for is DRM so the console “knows” you own the game. If you didn’t need the disc in the drive to play, you’d be able to give the game to anyone else to install and play without the disc. Well, you can let a friend borrow your game to play, but they won’t be able to continue to play if they return the game to you unless they purchase their own copy of the game.
