[Samba] transfer users after samba upgrade to new server

Thank you Dale.

Actually I did this by importing smbpasswd with
pdbedit -i smbpasswd:smbpasswd

And it works in the sense that my users can map a drive with their same 

But I have something else to consider.
The old server was a domain master and so I have some win XP machines 
that login to it and there is a netlogin.bat etc.
Given that all of the user password and machine passwords are now 
imported I wonder if that will continue to work when I switch over.
If anyone has any insight on this I would appreciate it.
I will be performing a test switch  over on Monday at noon 
Guelph,ON,Canada time.
