Thanks Marc,,

I have succeeded  in swapping the server.

Currently i am using 4.1.5 version on CentOS 6.3 bit. But if i want to 
change my OS to 6.5 will there any thing else i have to do OR just 
transfer the /usr/local/samba

After reading this https://wiki.samba.org/index.php/Updating_Samba

If i installed samba new version 4.1.7 on other standby server and then 
I compile samba 4.1.7, can I just copy the /usr/local/samba to the 
working server.
