If it was me, I would WGET it. I have ftp to move files and sites, but you would have to install the software first.
cp /usr/local/apache/conf/httpd.conf /home/sites/yoursite/web
(copy the httpd.conf file to one of your domains so you can wget it)
on your new server
wget
http://www.mydomain.com/httpd.conf
once you get it,
cp httpd.conf /usr/local/apache/conf
Make sure you backup your old one FIRST!!!
cp httpd.conf httpd.conf.bak
I haven't tried it, but in theory it should work. You might have to use switches with the cp command to overwrite the old httpd.conf file
