I'm attempting to import posts from one WP 3.2.1 site to another using WordPress Importer 0.5. Things seem to be running smoothly, except that URL slugs (post_name in the wp_posts table) are not imported, which results in some posts having different URLs on the new site. This affects posts that have edited URLs; posts that do not use the default WP-generated one. This is a pretty big problem for people doing site migrations, as a simple domain redirect to the new site will result in lots of broken URLs.
I've confirmed that the post_name is exported correctly and does appear in the XML file. Something is happening upon import though, and the post_name fields in my database are all the default slugified version of the post titles. I've verified this problem using exported data from two different WP sites, importing to two different other installations.
Anyone else seen this or know a fix?
