So I’ve got a 1tb OLED arriving today, and I’m going to have to transfer all the data from my current 256gb deck to it because my mom is going to be giving it to my dad for Christmas (she bought it off me). Is there an ideal way to do this?

I’ve used a program on windows before that did this sort of thing where it would turn the entire disk into a glorified iso file and let you burn it on another one. Is there a version of that for Linux drives like this?
