Alright, if you’re moving from Bunny Tags to Ultimate Tag Warrior. (like me), here’s what you should do to convert your previous Bunny Tags tags to Ultimate Tag Warrior tags. Incase you didn’t know yet, Ultimate Tag Warrior is a wonderful Wordpress plugin which enable you to convert your blog, from category-based blog system, into tagged-based blog system. Using tagged-based system is much more convenient than using category-based system. Many popular web applications are now using tag instead of category. Flickr and Del.Icio.Us to name a few.

Back to the topic. Here are 2 things that I did to move from Bunny Tags to Ultimate Tag Warrior:

1. Import Custom Field.
   Go to Manage – Tabs. On the very bottom of page, you can find the form to either Import or Export custom field. Enter “tags” (without quote) and press Import Custom Field. This will grab your previous Bunny Tags tags from each post and make them Ultimate Tag Warrior tags.
2. Modify Multi-Word Separator.
   If you’re using the hack for your Bunny Tags to enable multi-words tag, you possible use ‘+’ (plus) character as a separator. For example: “blogging platform” is “blogging+platform” if you wrote it in Bunny Tags tag. The problem is, Ultimate Tag Warrior use either “_” (underscore) or “-” (dashed) character for multi-words tag. Since there’s no mass-editing feature to rename tags on Ultimate Tag Warrior, you have to deal directly with your database.
   Open your PHPMyAdmin. Choose the database of your blog. Select SQL. Now enter the following SQL query:

   update wp_tags set tag = replace(tag,'+','_');

   Execute the query. This will modify Ultimate Tag Warrior tag table and replace the ‘+’ (plus) character with ‘_’ (underscore) character. Of course, you have to do step 1 first before you do this.
   Note that this step is not necesarry if you’re not using the Bunny Tags hack.

That’s it :p
