[Samba] How to properly demote a W2003 from Samba4?

Greetings, Sam!

> Hello all,

> I'm always trying to migrate from W2000 server to Samba 4.

> For doing this, I tried this :
> - install a W2003 server with AD and DNS services, join it to W2000, 
> transfer roles and after demote the old W2000 -> done
> - install a Sernet Samba4 with Bind9, join W2003, transfer roles -> done

> At this point the sync process is working in two way, I can manage DNS 
> and AD with rsat tool even directly on the Samba4 server... Which was

> Now I can't demote the W2003 server, the only way I find is to use

> don't work... )
> But now Samba4 always trying to contact the w2003 server and I can't

> "domain controllers" section of the AD...
> if I try "samba-tool domain level raise --domain-level=2008_R2" I read 
> "ERROR: Domain function level can't be higher than the lowest function

> So how to do a clean demote process even manualy? ( I can't set up a

> Thanks for helping! :)

Did you transfer all seven roles?
