How to update the Hypervisor from Version 1.X to Version 2.X

To update to the newest Version 2.XX from 1.XX it is necessary to follow these steps:

  1. backup all VMs to a large enough USB drive
  2. update to 2.XX via the recovery stick: 1.4 Factory Reset and Recovery (Appliance)
  3. convert the backups to the new backup format in the Backup GUI of the 2.XX Hypervisor
  4. Restore the backups

NOTE: LVM is much more performant, so the update will not only bring more stability, it will also boost the speed of the VMs.
