Can I play PS4 games on PS5 through streaming?
Yes, streaming PS4 to PS hosts through Remote Play and PS Now streaming are both supported. The benefit of streaming is to save storage space on the PS5. Please note that you cannot enjoy the "Game Boost" feature of the PS5 console when playing PS4 games through streaming.
How does PS4 game transfer and game archiving work between two platforms?
You can use a LAN cable or connect to WiFi to transfer digital games, game data, and game archives from the PS4 console to the PS5 console. If you have already stored PS4 games and game data on an external USB storage device connected to PS4, you can use that USB device to transfer these contents to the PS5 host. In addition, if you are a PS+member, you can also synchronize the PS4 game archive on the PS5 host through Cloud storage.
Please note that whether the PS4 and PS5 versions of the same game can achieve archive transfer is determined by the developer, and the situation of cross generational games may vary.
As for the two games "Marvel Spider Man: Miles Morales" and "The Adventures of the Muggles", when players decide to upgrade from PS4 to PS5, their game archives can be transferred.
