I have a friend who is interested in FFXIV and does not own a PS4 (yet). His PC is very old and cannot run FFXIV, so I want to let him play the demo in my PS4.

Is it possible to install the full game (the one I usually play on) and the demo version on the same PS4 console, or would that damage the installation of the full game?

All the best,
Zazanima
