help me move my user profiles

I have put up a new server on the same domain and have been able to copy over approximately 1/2 of the user profiles (roaming) that are on my network. However, the balance of them give me access denied, or file in use errors when I try to copy the profile. I have taken ownership of the profile, as well as made sure the particular people are logged out of the network.

Is there an easier way to move the profile to the new server without the hassle I’m experiencing?

Thanks
