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.
