How can I keep my old procreate art on old iPad Pro and use new iPad Pro to create new art on same app

My iPad Pro (5th gen, 128GB) got low on storage mainly using procreate on it. I don’t have Apple computer to save my art on, but just got another iPad Pro (5th gen, 256GB) I transferred everything to the second iPad but I would like to know if I could delete the files on procreate from only my new device so I do not take up so much space on this second iPad, and keep those old files on procreate only on old, and create new ones on the second one. Is that possible?
