In my case the migration following was quite easy without any trouble. 
Thank for Samba team!
I followed 
then transferred roles, copied GPO and so on.
As actually I migrated from Win2000 AD DC, I first upgraded to Win2003.
I leaved DNS zone on existing BIND NS and added manually all necessary 
records for new domain controllers (I got required entries list with 
"samba_dnsupdate --verbose")
I only get this bug: https://bugzilla.samba.org/show_bug.cgi?id=10130, 
but I fixed it by removing userParameters entries.
And now I just wanted  in the same easy way to transfer uid/uidNumber 
from openLDAP to Samba4 DB.

Thanks for your toughts!
