From RHEL to CentOS BIND 9

[isplist at logicore.net]

I need to move my RHEL BIND DNS over to a CentOS BIND 9 server along with 
building a secondary. Both new machines are RPM installs so no source.  

The machine are ready to go but I can't figure out how to migrate the records 
over to the new machine along with creating a secondary from the first machine 
once it's done. 

I've looked everywhere I can and find tons of documentation but of course, 
nothing which matches what I'm doing. Can someone lend me a hand with this and 
give me some input on what I need to do next.

Thanks.

Mike
