Need to change your table prefix from wp_ to something else on a site that’s already running? Not running a multisite install? Rename DB Table Prefix can probably help.
RDTP’s primary functionality is based on the great WP-CLI package, wp-cli-rename-db-prefix.
Use at your own risk and make backups before running this plugin – it is entirely possible that this could break your site and you will need to be able to restore your database and wp-config.php files from good backups if this happens.
This plugin is available for download for your site.
