Just to make sure... you're aware that you can only have one SSL-enabled
site per IP, but that this site *can* share the IP with lots of
non-SSL-enabled sites? The SSL site must be the only SSL-secured site on
the IP, but it doesn't have to be *the only site* on the IP.

Yes.

Yes. Set the TTL values to something low (like 1 hour) and leave them
that way for several days. Then change the DNS to the new addresses and
return the TTL to a normal value. Hopefully most people respect caching
limits and hopefully many people don't even notice. Those that don't
respect expire times, or those that queried your DNS within the last
hour, will see the site as down until they refresh their DNS.

If you've made any changes to the httpd.conf file, you should restart
the *web* server... not the machine itself.
