Hi Marc , thanks for answer, 

First of all I have to apologize for my english :) . 
The domain have a lot of problems: clients are disconnecting from domain continuosly, many many errors logs of dns(Its not working, I configured a bind9 in another server), missing libraries, etc. 
It is a bad installation by the guy was before me, and the company got some good hardwares, so I installed another samba4 like pdc following this instructions (http://mark.orbum.net/2014/02/22/compiling-samba-4-on-debian-wheezy-active-directory-domain-controllers-ho/) using one of the new machines, and I want to migrate just the users and their passwords from the actual pdc to the new one. 

** Info actual pdc: 
*samba -V 
samba: /usr/lib/i386-linux-gnu/libwbclient.so.0: no version information available (required by /usr/lib/i386-linux-gnu/samba/libauth4.so) 
Version 4.0.0beta2 
* hostname: pdc 
* samba-tool domain info 
Forest : valcocr.int 
Domain : valcocr.int 
Netbios domain : VALCOCR 
DC name : pdc.valcocr.int 
DC netbios name : PDC 
Server site : Default-First-Site-Name 
Client site : Default-First-Site-Name 
*Debian 7.4 wheezy 
*domain 'DC=valcocr,DC=int' 

* /etc/samba/smb.conf 
# Global parameters 
workgroup = VALCOCR 
server role = active directory domain controller 
realm = valcocr.int 
netbios name = PDC 
passdb backend = samba4 
dcerpc endpoint servers = epmapper, wkssvc, rpcecho, samr, netlogon, lsarpc, spoolss, drsuapi, dssetup, unixinfo, browser, eventlog6, backupkey, dnsserver, winreg, srvsvc 
server services = rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate, smb 
log file = /var/log/samba/log.%m 

path = /var/lib/samba/sysvol/valcocr.int/scripts 
read only = No 

path = /var/lib/samba/sysvol 
read only = No 

directory_mode: parameter = 0700 
read only = no 
path = /Users 
csc policy = documents 

**New pdc 
root at atlante:~# samba -V 
Version 4.1.13 

*hostname: atlante 
* domain 'DC=atlante,DC=valcocr,DC=int' 
*Debian 7.4 wheezy 
*Original smb.conf from installation , no modifications . 

Thanks for you interest.

Do you have any problems with your domain? Or what is the reason for 
this extra effort? 

If there's really the need for such a procedure, then you should give 
more information. Samba version, passdb backend, etc.
