Bye bye Windows 2003 AD, hello Samba 4

Hi,

We have a existing domain (blahblahblah.org) where we have a running MS Windows 2003 as PDC (using old term "PDC" to be clear).
Many of our new internal software applications run on CentOS 5.x/6.x servers (so we have a good experience with that linux OS).
Those CentOS servers have not yet joined our Windows 2003 domain. Until now that wasn't necessary.
The big project we're facing is to completely go away from the default Windows Server as PDC and choose for a domain with only Linux Servers completely overtaking the AD (DNS, user authentication, etc)
So, we would like to do that migration into small steps.
The first step is of putting linux boxes into the Windows 2003 domain, some as additional domain controllers, others only as member servers.
Both configured with samba 4.
In the second step one of these additional domain controllers would become the PDC of the domain.
At the end we would not longer use Windows Servers.

Remark: We have multiple sites (with different LAN ranges) under 1 domain. Per site we want to replace the Windows 2003 domain controller with a CentOS 6.x - Samba4 configuration.

Searching google i can only find the first step...: on the wiki of samba (Join a domain as a DC)

But i like to know how to upgrade the additional domain controller to a PDC and fire the former Windows 2003 PDC.

Can anyone help me with that second step?
