What is the easiest way to transfer procreate files from an older iPad to my new one?

I am replacing my 64g 7th gen iPad 10.2”

with a new 256g 10.2” and I am curious as to how my procreate files can transfer to my new pad. Will they just be there when I sign in to the new device or is it going to be a process of saving them onto a drive or something?
