how do you plan to swap the games from the 2TB drive to the 4TB one if and when you buy one?

I think I saw one on sale on Best Buy for almost more than the price for the PS5 itself. It would be cool to have that much storage on deck, but that's a pretty steep price point IMO. Luckily, the game library for the PS5 is still kinda bare so that storage isn't a deep need for me to go beyond the 2 TB drive that I copped months ago.
