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)
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
