/3/ - 3DCG

Blender gents, I have this mesh here. It's an upper jaw(teeth). As you can see I've created UV maps for it.
I also have a high poly version with matching seams. Is there a way to transfer the UV layout of the low poly to the high poly mesh so that they match?
I'm actually trying to bake AO maps. When I try and bake from the high poly to the low poly I get a lot of clipping artifacts though. This is why I am thinking If I can just get matching UV layouts for both I can just bake an AO map of high poly alone, an then use it on the low poly.
