From RHEL to CentOS BIND 9

Hi Chris,

Thanks for the help.

I'm going from bind 9.2.5-3 to bind 9.3.3 on the new CentOS servers. All 
versions are chroot.

So basically just copy all of the zone files and named.conf over to the new 
servers and edit configurations from there once they see the information?

I think something is messed up on the old dns server. I just tried to tar the 
whole thing up and that ruined my named.conf. Luckily, I had a backup so my 
DNS server is back up.I also see that /proc is now linked to my 
/var/named/chroot dircetory. Guess I need to learn a little about chrooted 
things :). So, how can I safely copy all that I need for the new server then?

This was something that caught my attention. The named.conf files are indeed 
in /var/named/chroot/etc but no links to /etc/named.conf were created by the 
installer RPM. I added those myself later. There is a link for the rndc.key 
however.

I'll move on to slave once I get this one working or this message will end up 
being hugely long :).
