There are times when moving or copying WordPress blogs from one server to another, the owner may want to update the URL associated with the specific site.

A simple MySQL update can match the WordPress blog to a new site URL:

mysql> select option_value from wp_options where option_name = 'siteurl';

+--------------------------------+
| option_value                   |
+--------------------------------+
| http://www.example.com |
+--------------------------------+
1 row in set (0.00 sec)

mysql> select option_value from wp_options where option_name = 'home';

+--------------------------------+
| option_value                   |
+--------------------------------+
| http://www.example.com |
+--------------------------------+
1 row in set (0.00 sec)

mysql> update wp_options set option_value='http://server.newsite.com' where option_name='siteurl';

Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> update wp_options set option_value='http://server.newsite.com' where option_name='home';
