Detailed upgrade and installation instructions are always in the readme for the version youre installing. A simple upgrade is done either command line with install2disk or from the gui. The install goes to a new volume so you can boot, check the new version and if youre not happy, fallback by simply rebooting again to the old volume slot.
The hypervisor is just another copy of bigip. It should upgrade just like a guest or standalone bigip, But of course you need to make sure all your guests are running their groups in standby.
