[Samba] migrating from samba 3 to samba 4

Hi all, after the news that samba 4 is now supporting user lockouts after
bad password attempts we need to plan our roadmap on migrating from Samba 3
to samba 4.


We currently have Samba version 3.0.7-1.3E.1 installed with (passwd)
database as a backend.


I would appreciate if anyone can guide me on the migration process.


Our old server


Centos 4.4

Samba 3.0.7

(Master browser)


Our new server


Centos 6.5

Samba 4 (DC/AD)


Any guidelines on how the migration would work. We have not implemented
roaming profiles on the old setup and we are not planning on implementing
roaming profiles on the new system ether. 


My main concerns are:


We want to change the (domain name) which user's login to and don't want
anything to happen with their current profiles on their PC's. (Is this
advisable to change the domain name or must the domain name stay the same?)
This is the internal domain the users select when they log into their PC's.


So the plot thickens. How do we get the samba3 profiles onto the samba4
domain with as little changes to the user setup on their PC's?


What I mean by profiles is the local profile of the user on the local PC...
not roaming profiles... I know by experience that if something happens to
samba3's use account then it messes up the local profile on the PC and I am
trying to avoid this when I migrate to samba4


Any help mush appreciated.


Thank you
