Samba 4 is not out yet; the Samba 4 Technical Previews are not
recommended for production use.  I'm not aware of any docs or howtos
on how to migrate from Windows AD to Samba 4 AD.  (I *think* that I've
seen comments about the Samba team working to get full-fledged AD
replication working in Samba 4, which would mean that migrating to
Samba should be as simple as promoting a Samba 4 DC then demoting the
Windows DC.  But I don't know that Samba 4 can do that yet.)

Samba 3.x cannot serve as an Active Directory domain controller.  It
can serve as a NT4-style domain controller, but I suspect that you
would need to rejoin all of your computers to switch from a Windows AD
domain to a Samba NT domain.  If your Active Directory domain is still
in mixed mode, then I imagine that you could at least migrate users
using Samba's net vampire command
(http://samba.org/samba/docs/man/Samba-HOWTO-Collection/NT4Migration.html),
but it's not something that I've tried.
