Explanation: Upgrade Virtual Hardware
You can upgrade the hardware version of virtual machines to the latest version of ESXi. For virtual machines that are running on ESXi 5.x, VMware recommends that you upgrade the virtual hardware to version 8. Consider the following points:
• When you upgrade from virtual hardware version 4 to version 8 the upgrade is reversible if you take a virtual machine backup or snapshot before performing the upgrade.
• Upgraded virtual machines cannot be powered on by an ESX 2.x host, even if relocated to a VMFS2 datastore.
• To automate this process, consider using Update Manager for virtual machine upgrades. See the Installing and Administering VMware vSphere Update Manager documentation. Update Manager takes automatic snapshots before performing virtual machine upgrades. See Perform an Orchestrated Upgrade of Virtual
Machines with vSphere Update Manager.
• When you upgrade virtual hardware, no downtime is required for vCenter Server or ESX/ESXi hosts. For virtual machines, the only significant downtime is the time to reboot the guest operating systems.
