Thank you for your responses guys. Here is a n00b question: Because this new server will be a slave DNS server, do I have to manually copy the zone files from the current slave DNS server (The CentOS 5.11) one, or does the new server automatically get the zones from the master DNS server?

Thank you for your response. Basically what I am trying to do is migrate the BIND server from a Centos 5.11 machine to a CentOS 7.2 machine. The BIND on CentOS 5.11 was compiled manually by source and its named.conf file looks very different than what CentOS/Red Hat provides in the RPM package
