Thanks Ankur, I knew there had to be an easy way to convert some wordpress tags to categories.

Much Appreciated

You can run the SQL:

UPDATE `yourdbname`.`wp_term_taxonomy` SET `taxonomy` = ‘category’ WHERE `wp_term_taxonomy`.`taxonomy` =’post_tag’

Please not that you will have to reconstruct the hierarchy;

As far as I remember, I wrote this post when I was using 2.6. Even if it wasn't 2.6 (I doubt that), basic things such as wp_term_taxonomy aren't changed between versions. If it's a mission-critical thing then take a backup of the database you're working on, then make the changes. If anything goes wrong, then you can use phpMyAdmin to import the backup and restore everything to its original state. WP-DB-Backup is an excellent plugin for this task.

Thanks Ankur.
A client wants to turn categories into tags and visa-versa (for reasons too complicated to go into here) and I suspected it was as simple as swapping the taxonomy values in wp_term_taxonomy… It’s good to have confirmation;-) I’ll be doing this in WP 2.6 but I’ve an idea things might be different in 2.7

@Mark: Phew, lucky escape for you. :) Yes, most people (quite correctly) believe that WordPress won’t delete the categories, and get into a lot of trouble when they go ahead and do it.
