The upgrade for all our components is always:

* BACKUP your sites files and database
* and BACKUP your sites files and database again!
* Download the latest version from myJoomla.com
* Make sure your backups are useable!
* uninstall all related mambots/modules/core patches that the component provides
* uninstall component
* install component - got ot the component in the Components Menu - follow the onscreen prompts.
* reinstall and patches/mambots/modules using built in installer in the component.

We are different to many component developers because our installs are full versions and upgrades all in one. Especially the newer components (JoomlaTags and JoomlaKB) as the bfFramework they are bult upon handles the complete database schema updates as well.

Also we are different in so much as when you uinstall our components we NEVER delete/drop/dump your database tables for that component! This means the data is safe in the database and when you install a newer version of our products the data can still be got to and used using the newer components interface.
