See this post by @Jake Bunce http://xenforo.com/community/threads/apache-redirects-to-nginx-help.61178/#post-654428
Those redirects are currently in place.
We are changing the domain from 3.7mustang.com to v6mustang.com
What we need to happen is that all the previous vBSEO redirects under 3.7mustang work but eventually be passed on to the v6mustang.com we are changing to.
What is the best way to do this under nginx?
