Tree Question!

Hi! I live in Georgia, and we have a lot of baby maple trees popping up in our backyard. We also have several large, very old, established maple and oak trees. I have to move the little maple seedlings and was wondering whether they would have better odds of surviving if I transplanted them near the existing trees and their root systems, or if they would be better off planted elsewhere. They currently have a couple of leaves and are about 5 inches tall.
