I'm in the process of migrating my existing blog to WordPress (2.0.4). I will be using the "Date and Time Based" standard permalink option, i.e.,
http://jclark.org/weblog/2006/08/18/sample-post/. However, on my existing blog, I use category-based permalinks, such as
http://jclark.org/weblog/category/sample-post/. I want to continue supporting existing links to my content, but I don't want to set up 300+ permanent redirects.
With my permalink structure set to date-and-time, category style links aren't recognized (404). With my permalink structure set to a custom structure
/%category%/%postname%/, all my category links work, but date-based permalinks aren't recognized (404).
How can get WP to recognize category-style permalinks, while use date-and-time permalinks as the default? I've looked for plugins, and haven't found anything so far. I'd be willing to hack at the code and/or build a plugin, but I'm still poking around the edges of the codebase, trying to understand how everything work.
Also: Links to the categories themselves are fine, it's just category-style permalinks to posts I'm having an issue with. I'd even settle for a plugin that finds the linked post and 301's to the new url... I just don't want to orphan my old permalinks
