[Samba] migration from 2.2.4 to 3.0.10

[peter grotz]

hi all,

I want to migrate my samba 2.2.4 pdc with roaming profiles and shares to a
new installed samba 3.0.10 pdc.
How must I go on to migrate my users and their profiles from the old server
(with smbpasswd) to the new pdc running with ldap-passbackend with out
loosing the profiles and passwords?
For the share´s and profile´s data I´m using rsync but what about the
NTUSER.dat?
Does the "net vampire" work with 2.2.4?

Are there any howtos for this special case?

Thanks in advance,

-Peter
