Transferring user profiles to new domain

[Ole Begemann]

Hello experts,

I have set up a Samba 2.1 PDC (Domain: NEWDOM). Now I want to transfer all
the user profiles from our old domain OLDDOM (NT4 PDC, profiles stored on a
Samba 2.0.4 box) to the new one so that the users won't recognize any
difference. Is there a kind of step-by-step-documentation available? I just
tried to create a user on the new samba box and copy one his old profile
directories to the new location, but it doesn't work, the old profile is not
used.

Thanks very much for your help.
Ole
