I do now. One step further, but now:
"Traceback (most recent call last):
   File "./samba_upgradeprovision", line 37, in <module>
     import samba
ImportError: No module named samba

I hope it's the last problem...


AH, light dawns ;-)

Your python doesn't know where all the python modules are, investigate
on how to set 'PYTHONPATH' on Centos.


That did the trick. Thank you.
But unfortunately...

[root@dc bin]# ./samba_upgradeprovision --realm=DOMAIN.NET.PL -U Administrator Found 5 domain controllers. For the moment upgradeprovision is not able to handle an upgrade on a domain with more than one DC. Please demote the other DC(s) before upgrading Sanity checks for the upgrade have failed. Check the messages and correct the errors before rerunning upgradeprovision

Is there any other way to increase KVNO, or I should try with demote and rejoin the main DC (with FSMO roles transter)?
