[Samba] migrate from winnt pdc to samba pdc

[Thomas Angst]

Hello list,

I would like 'upgrade' our client from winnt server to linux server with 
samba.
Unfortunatly are they using the winnt server as a domain controller.

The question is, how can I switch the profiles, stored on the winnt 
machine, to the new samba server.
(without loosing information in the profiles :)

any helps are welcome, I don't know what I can do more....

Thomas
