I am already running my WP blogs at http://www.xyz.com. I was thinking that after the WP-MU installation at http://blogs.xyz.com my users which already register with http://www.xyz.com (already WP 2.8.5 running blog) will be able to access http://blogs.xyz.com (WP-MU) with their same user name and password but it seems totally different two bloging platforms.
I want to connect WP-MU (new) with my WP 2.8.5 (already running wordpress) where my register user can assess both WP-MU and WP 2.8.5 with same login name and pwsswords.
Do I need to install WP-MU in root directory with my WP 2.8.5 http://www.xyz.com or WP-MU will work in subdomain with my root directory?
or
Do I need to remove WP 2.8.5 and install WP-MU in my root direcotry http://www.xyz.com and transfer my previous posts from WP-2.8.5 to WP MU?
thanks
