I think a mkdir is missing...
I wonder if, to minimize the downtime, the following would work:

mkdir /data/cache.new
chown nobody:nobody /data/cache.new
squid -z -f /etc/squid_conf_with_datadir_is_cache.new.conf
stop squid
mv /data/cache /data/cache.old
mv /data/cache.new /data/cache
start squid
rm -rf /data/cache.old

Could you even keep cache.new and just copy it as cache each time, so no need to squid -z each time...?

stop squid
mv /data/cache /data/cache.old
cp -a /data/cache.new /data/cache
start squid
rm -rf /data/cache.old
