I am "moving" to a new domain. The old domain simply (or not so simply) needs to send everyone to the new domain. The folders differ on the new domain and I am having trouble getting more than the old main page to redirect to the new domain. If people follow a search engine's link to a product page, it stays on the old domain rather than redirecting to the new domain. Is there a way to add something to the header.php to redirect? If so, what's the path to the specific header.php page? There seem to be a lot of them.

Is there a better solution?

Thanks,
Christy
