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.
