Just in case you didn't have it and if I understood it well...  I came up
with this in a quick attempt:

V="$(dpkg --status squid 2>/dev/null|sed -n "s/^Version: \(.*\)/\1/p")"
if [ -n "$V" ] && dpkg --compare-versions "$V" lt '2.8' && test -d /etc/squid3; 
then
        mv /etc/squid/squid.conf /etc/squid/squid.conf.pre3.5_upgrade
fi

Regards...
