Make sure you backup your database before doing this
Export your database with all tables/data. Then open it up in a text editor and then search/replace wp_ with something that you want. For example you can change them all from wp_ to ik_
Then highlight all the tables in your db. Then drop the tables. Don’t delete the tables, dump them. Then import your new sql file with the changes you made to the wp_. Then you need to change your wp_config.php file to reflect the wp_ change:
$table_prefix = ‘wp_’;
Change that above wp_ to the new name you gave it. In my example you would change it from wp_ to ik_ then save and upload the file and you’re done.
Now you might have issues with your blog not showing up on the site. That has been an issue. Don’t have a fix for that yet.
