I'm migrating a Joomla 1.5 site to a WordPress 3.1 site (I will later update to WP 3.2.x) and I've found the right tool to do it, a plugin called Joomla 1.5 Importer. There is another plugin called Joomla/Mambo To WordPress Migrator that works better except for one problem: there's no way to correct the database charset. The site is in Spanish, and some special characters are not shown correctly.
After usin the Joomla 1.5 Importer I've got my posts in place, but there is a permalink issue. Our current Joomla site has a permalink structure that includes the article's id:
But after applying the plugin the WordPress' article permalink is the following:
You see? There's no number at the beginning of the last part of the permalink. I guess I would need a Rewrite Rule in Apache for my .htaccess to solve the issue, but I don't know what would be the right one. I just need to "delete" the "id-" part of the permalink.
