samba - Jun 2010 - migration of PDC tdbsam backend to BDC - failed to fetch domain database

Hello

According to NT4 Migration Using tdbsam Backend 
http://samba.org/samba/docs/man/Samba-Guide/ntmigration.html#id2604610 I 
would like to transfer PDC settings (users,groups sids) to BDC and later 
make from BDC PDC machine.

I have Fedora Core 7 PDC(hostname serwer) and Centos 5.4 BDC (hostname 
serwer2) both on tdbsam backends.
I have copied smb.conf, passwd,group,shadow,secrets.tdb files from FC7 
to centos 5.4

I have changed smb.conf on Centos BDC :
-domain master =no
-netbios name = serwer2

all rest settings are the same like on smb.conf from PDC.

What version of samba?

The "vampire"  command can be used to pull account info from an NT4 
server into a Samba 3.x domain.  I am not sure if it can be used against 
a Samba 3.x server.  I could be wrong.   Samba 4 would be a different 
situation.

You may be able to copy the samba private and samba locks directories 
over from PDC to BDC instead.

Samba PDC Version 3.0.28a-1.fc7
Samba on BDC 3.0.33-3.28.el5

What means an error ?
Fetching DOMAIN database
FAILED to fetch domain database: NT code 0x1c010002

I thought that if samba is NT4 domain "emulator" tools of migration
are
the same .
So what are the methods of tdbsam migration ?
Am I only copy smb.conf and all .tdb files from /var/lib/samba/private
or whole /var/lib/samba/ ??

I don't want to re-adding again windows clients to domain.

If I copy .tdb files (passdb.tdb, schannel_store.tdb, secrets.tdb
smbpasswd)from /var/lib/samba/private domain sid will not change ?


In official how-to there is no information how to migrate samba from samba
serwer to new samba serwer, (only nt4 domain to samba).
Where can I find information about it ??

Please help
