I've searched alot but couldn't find what I want, so I am posting here hoping someone will help.
I have a site running on wpmu and currently I have almost 800 blogs. I decided to change my current domain to a new domain e.g currently all my blogs are on blog.com, my new domain is blog123.com.
What I want is to transfer all blogs to the new domain (blog123.com) and allow blog posts on the old domains to resolve to the new domain.
So if you click on the above link "Old domain post" you will be forwarded to the same post on the "New Domain post", that's exactly what I want.
appreciate any response. thanks in advance.
