Save you configuration in a file before to upgrade the system by following this tutorial.


  • Reverting to a previous build does not revert the tools-light vib version installed on the ESXI host
  • Reverting to an earlier version is not possible after upgrading to ESXi 7.0 due to partition changes to the boot device.
  • To use an earlier version of ESXi after upgrading to version 7.0, you must create a backup of the boot device before the upgrade or reinstall the desired version.

The upgrade requires the host to be rebooted.

Please ensure that you are running SynetoOS 4.7.0 or above before starting the upgrade procedure.
