I used to use an older SEF component but found that when I installed a new component it was no longer compatible so I'm now using JoomSEF. The only problem is that JoomSEF combined with this other new component generate slightly different SEF URL's. I don't have a problem with this but many links that Google and other search engines not to mention links from other sites are all giving the old SEF URL and so are getting my 404 page.

What I want to do is set a redirect so that the old SEF URL now points to the new SEF URL but the 301 redirect page in JoomSEF seems to demand that the old URL be a non SEF one i.e. starting with index.php which obviously my old SEF URL's don't have.

Any ideas?
