User Profile Folders Migration

We have bouild a new Domain, I have manually populated it with users. Now I need to move folders that contain user profiles, our users use roaming profiles, from FS in old domain to a FS in the new domain. There is no trust between domains they are completely separate. I do not want to save any premissions I will set new onece later. As I understand, just by copying user folders to a FS in the new domain will not work. Is there a software that will help me to accomplish this?
