I've been using ..

ezjail-admin update -i

 .. to update the binaries after a full update of the host system and
something like ..

#!/bin/sh
for JAIL in {list-your-jails-here}
do
        mv /usr/src /usr/local/jails/${JAIL}/usr
        JAIL_ID=`jls | grep $JAIL | awk '{ print $1 };'`
        echo "Updating: ${JAIL}"
        jexec ${JAIL_ID} mergemaster -scvi
        mv /usr/local/jails/${JAIL}/usr/src /usr
done

 .. to update/merge with jail-specific config data,
