I VMware recommends that before you upgrade the virtual hardware, first upgrade VMware Tools
MPORTANT
on the virtual machine. This is especially important for virtual machines with Microsoft Windows guest
operating systems. On Microsoft Windows virtual machines, if you upgrade the virtual hardware before you
upgrade VMware Tools, the virtual machine might lose its network settings.
To automate this process, consider using vCenter Update Manager for virtual machine upgrades. vCenter
Update Manager ensures that upgrade procedures happen in the correct order. See the vCenter Update Manager
Administration Guide.
For those virtual machines with Microsoft Windows guest operating systems that have static IP addresses,
VMware also recommends that you configure your DNS server such that these virtual machines do not have
write access to their A records for their fully qualified domain name. This ensures that the DNS records for
these virtual machines remain intact during the upgrade process.
Procedure
1 Power off the virtual machine.
2 From the vSphere Client, right-click a virtual machine in the inventory and select Upgrade Virtual
Hardware.
The software upgrades the virtual hardware to the latest supported version.
The Upgrade Virtual Hardware option appears if the virtual hardware on the virtual machine is not the
latest supported version.
3 Click Yes to continue with the virtual hardware upgrade.
4 Power on the virtual machine.
If the virtual machine has a Microsoft Windows guest operating system, the operating system detects a
new device, configures the device, and prompts you to reboot the guest operating system. If any unknown
devices are recognized, the operating system prompts you to configure the device manually.
5 For Windows guest operating systems, reboot the guest operating system to make the changes take effect.
The virtual hardware version is 7 on the VM Version label on the virtual machine Summary tab.
