Upgrading an ESX 3.x virtual machine to ESX 4.0

Purpose

This article provides information about upgrading an ESX 3.x virtual machine to an ESX 4.0 virtual machine.

Resolution

To ensure your virtual machine is upgraded to ESX 4.0, you must:

  3. Shutdown the virtual machine and the upgrade virtual hardware.
  4. Power on the virtual machine.
