10 IP addresses is no big deal, unless perhaps you have a huge
number of sites.

Good that the secondary is elsewhere.  Better if all DNS servers
always respond; consider making the secondary _both_ secondary
and primary during the move.

Edit DNS by modifying /etc/named/conf, but change the sites' IP
addresses in the GUI.  You might also write/use a screenscraper,
although renumbering the sites doesn't take long at all when DNS
is already done.
