Hello Everyone,

I'm building a environment with 2 samba4 domain controller with 2 DNS 
servers, i started working and thought of upgrading the existing samb4 
install which is

Samba 4.0.0alpha11-GIT-802e932 on CentOS release 5.4 (Final), as per the instructions in "upgrading-samba4.txt" i get errors as follows

Traceback (most recent call last):
   File "./scripting/bin/upgradeprovision", line 49, in ?
     from samba.misc import messageEltFlagToString
ImportError: No module named misc

Please let me know if anything else is required to do the upgrade
