Howto upgrade a Wordpress installation, see Upgrading Wordpress.

1. Back up your database
   1. Back up ALL your WordPress files (all wp files, .htaccess, etc)
   2. Verify the backups (do they unzip/tar ok?)
2. Deactivate ALL your Plugins
3. Overwrite Files
4. Run the upgrade script (http://example.com/wordpress/wp-admin/upgrade.php)

• When there has been no database changes, so a minor upgrade

1. Unpackage latest.tar.gz and you get wordpress dir, rename it to a unique name
2. Move your old wp-content, wp-config.php, and .htaccess to the new dir
3. Change your symbolic link for blog to point to new wordpress dir

wp-config.php  wp-content .htaccess
mysqldump --add-drop-table -h localhost -u DBUSER -p DBNAME -c > DBNAME.DATE.sql
