I would do it this way, the "$1" = "1" ensures, that this is only performed 
once the package is installed for the first time and according to my 
understanding does this make rpm create if .rpmsave files if needed.

%pre
if [ "$1" == "1" -a -f /etc/l2tpd/l2tpd.conf ]
then
	cp -p /etc/l2tpd/l2tpd.conf /etc/xl2tpd/xl2tpd.conf
	cp -p /etc/ppp/options.l2tpd /etc/ppp/options.xl2tpd
	cp -p /etc/l2tpd/l2tp-secrets /etc/xl2tpd/l2tp-secrets
	sed -i "s/options.l2tpd/options.xl2tpd/" /etc/xl2tpd/xl2tpd.conf
fi

I did not find any hint on how to perform this task, so maybe someone can tell 
whether this is better handled in %pre or %post.
