You need to uninstall the older Qube components, and then install the newer ones. No data is lost during the uninstall/re-install.
Stop the supervisor and the Qube MySQL server
If you want to avoid a reboot during the uninstall/reinstall cycle, you need to stop the following Windows services, in this order:
- qubesupervisor (stop this first)
- pfxmysql
You can either stop these services with the Services utility, or at the command-line if you've open a cmd prompt as "Run as Administrator"
sc stop qubesupervisor
sc stop pfxmysql
Uninstalling the Qube Supervisor
The only condition is that the Qube-core is uninstalled last. You can uninstall all other Qube components in any order.
The most common order is
- uninstall the Qube supervisor
- uninstall the QubeGUI (if installed)
- uninstall the Qube-core
