I have a pretty old reviews blog that is well trafficked, nice PR with 1000s+ posts @ http://www.example.com. I would now like to create ecommerce site on related subject matter. I don't want to commingle blog and ecommerce site so subdomain seems to be logical choice for blog. http://www.example.com would be the logical choice for ecommerce and blog.example.com would be choice for old blog. I will use wordpress for both sites.
This is the problem as I see it. If I use a mass 301 redirect from example.com to blog.example.com, example.com is useless. If I use a 404 redirect solution, I miss out on the possibility of using a monetized 404 on my ecommerce on http://www.example.com.
I could manually set 301 redirection for each post/page through cpanel or through the redirection plugin ( http://wordpress.org/extend/plugins/redirection/ ) but that would take a ridiculous amount of time.
I was wondering if anybody had a better solution. I can do some coding on my own or can have someone else do advance coding done for me if need be.
Thanks in advance.
