I'm migrating a couple of my company's WordPress 2.x blogs into a single WordPress 3 MultiSite install. I installed it into a subdirectory /blogs, as we are using a PHP framework to control the rest of our site, and selected the subdirectory option. I have been able to migrate our blogs into the WordPress network just fine. However, one of the requirements is that we retain the old URLs for this new install. (The old blogs are in subdirectories of root, such as /exampleblog.)
I've tried making some adjustments to the root .htaccess file to force /blogs/exampleblog to redirect to /exampleblog, but to no avail. I tried searching through this forum for an answer but couldn't find anything. I read a forum post for WordPress MU six months ago that said that because of the way that WordPress creates virtual folder, redirecting the URL is impossible. I am aware that most (if not all) of the features of WordPress MU have been folded into WordPress 3 Network, but I have to ask: Is this still impossible to do, or has WordPress (or a plugin coder) fixed this issue?
