How to Update WordPress 3.0

1. Back up the WordPress database that manages your website. A common method is to log in to your Web host account, access the cPanel and click the 'Download a MySQL Database Backup' link to obtain the gzip (gz) file. The backup process saves all of your posts in the event you need to go back to a previous Wordpress version.
2. Log in to your WordPress account and click the 'Plugins' link on the left. Click the 'Plugin' box to check all of your currently installed plugins, click the 'Bulk Actions' arrow, select the 'Deactivate' option and then click the 'Apply' button. Deactivating your plugins is an optional step, but it helps prevent any unnecessary problems during the WordPress 3.0 upgrade.

3. Click the 'Dashboard' link on the left and then click the heading that reads 'WordPress 3.x' is available! Please update now.' Alternately, click the 'Updates' link under the 'Dashboard' heading on the left.
4. Click the 'Update Automatically' button that displays. This action prompts a script to run and when finished, displays a message that your WordPress 3.x version was installed successfully.
