I am migrating our BIND system to a new server/BIND version, and have
a question about dynamically updated zone files (we have one dynamic
zone). I am just copying all the configuration and zone files to the
new server, do I need to run rndc freeze before shutting down bind
and moving them or will just stopping the bind service properly deal
with updating the zone file? Also do I need to copy over the .jnl
file when I do this or will a new one get generated as needed?

Not a stupid question, but an easy answer (man 8 rndc):

This command stops the server, making sure any recent changes made through dynamic update or IXFR are first saved to the master files of the updated zones.

So as long as you stop named with 'rndc stop', the zone file will be up to date. That also makes the journal file obsolete. So, you don't need to move that over. But it doesn't hurt if you do.

Before starting named on the new system, assuming your main configuration file is 'etc/named.conf', use:

named-checkconf -z /etc/named.conf

This will check your configuration and all your zones and tell you if anything is wrong.
