EDIT: THIS POST IS NO LONGER RELEVANT DUE TO THE BUILT-IN UPGRADE FEATURE OF WORDPRESS. COMMENTS ARE NOW CLOSED.
This is a video about how to upgrade WordPress using the Instant Upgrade plugin. In order to follow along you will need to have this plugin installed (it comes standard with any Ninja Blog Setup WordPress Installations).
[Note: if you don’t have the plugin installed, you can visit the Instant Upgrade project page to retrieve the latest version.]
WARNING: before doing any type of changes to your site, you should always perform a backup. The WordPress backup plugin also comes standard with all Ninja Installations, but if you don’t have it, then download and install the WordPress Database Backup plugin before you begin your upgrade.
Quite often the latest versions of WordPress are security updates and they should be performed as soon as possible.
