WordPress Database Switcheroo

First, do a MySQL database export of the old database on the old server, create a new blank database on the new server, import the old data either in PHPMyAdmin or mysql directly in the command line.

Make sure you have the new database selected, then run some SQL updates and replacement commands on the tables notably, wp_options, wp_posts, wp_postmeta.

Use the code as below and swap in your old and new URLs, no trailing slashes. Also if necessary change the table prefix values where applicable (ie wp_ )

UPDATE wp_options SET option_value = replace(option_value, 'http://www.oldurl', 'http://www.newurl') WHERE option_name = 'home' OR option_name = 'siteurl';

UPDATE wp_posts SET guid = replace(guid, 'http://www.oldurl','http://www.newurl');

UPDATE wp_posts SET post_content = replace(post_content, 'http://www.oldurl', 'http://www.newurl');

UPDATE wp_postmeta SET meta_value = replace(meta_value,'http://www.oldurl','http://www.newurl');

MySQL change and update WordPress URLs

or via command line:

username@[~/Desktop]: mysql -u root -p databasename
Enter password:

Rows matched: 686 Changed: 0 Warnings: 0

Finally update your WordPress config file to reflect the new database, wp-config.php” which should be in your web document root – change, databasenameusernamepassword and host values:

define('DB_NAME', 'databasename');

/** MySQL database username */
define('DB_USER', 'username');

/** MySQL database password */
define('DB_PASSWORD', 'password');

/** MySQL hostname */
define('DB_HOST', 'localhost');

Now everything should link up perfectly.

djave has created a nice and easy script that takes the old and new URLs and hands you the SQL code for the WordPress swap, nice!
