System Update GUI
The upgrade functionality is only available for PCBSD version 9.0-Beta1 and newer. This is a recent development to allow the user to upgrade to the latest version of the PCBSD operating system without requiring the user to re-install the entire system while preserving all user settings and data and PBI's (not installed ports however).
As such, there is *NO* upgrade functionality within the PCBSD 8.x series, so you will have to download the .iso image of your choice for the PCBSD 9.0-BETA1.5 version and reload your entire system.
Reminder: be sure to back up your *entire* home directory in order to preserve your data!
