VMware offer the option to upgrade the virtual underlying hardware on a VM, to the latest version that the VM host supports. The hardware options will depend on the environment the VM is within. It does not affect VM billing.
VMware does not recommend upgrading the virtual hardware version if you do not need the new features exposed by the new version.
Before a hardware upgrade, the VM must meet the following criteria:
|Has the latest version of the VM tools installed.||
NIC configuration may be lost when upgrading from ESXi 3.5 to a newer hardware version. To work around this issue, the latest version of VMware Tools must be running in the VM before commencing the hardware version upgrade.
For more information, see the VMware Knowledge Base: Installing VMware Tools in vSphere (2004754).
Note: This does not apply to guests running Linux distributions or FreeBSD releases that have vendor supported open-vm-tools installed in the guest.
|Does not have multiple snapshots.||
Before a VM upgrade, you must create a snapshot or backup of the virtual machine in case there are issues post upgrade. A single 'with memory' snapshot is recommended.
|Is powered down||
The VM must be available and not undergoing another activity.
Follow these steps:
1. Navigate to the Compute Overview page (shown below). This shows all your resources grouped by the services types you are subscribed to.
2. Locate the Service Type/Location of the VM you want to upgrade and click the blue Resource Number. For example, the screenshot below shows the selection of all the Managed VMware VM's located at the WPD datacentre.
3. The Compute Details page appears. Locate the VM you want to delete by using the search function and filters.
4. Click on the VM to view it's properties. Before you can start the upgrade, it is recommended that:
- The latest version of VM tools is installed. This is shown in the VM Tools field shown in the screenshot below.
- Only one snapshot of the VM in place - a 'with memory' snapshot is recommended. Select Backup and Recovery > Create Snapshot. A notification will appear if a snapshot already exists.
- The VM is powered down. Select Power Controls > Power Off.
Note: The upgrade is an automated 'async' activity which is performed in the background, and reported back when completed. The VM will be unavailable during the upgrade.
5. To start the upgrade, select the 3 dots at the right-hand side of the VM. Then select Utilities > Upgrade Hardware. There may be a few seconds' delay before the options appear.
6. A confirmation window appears. Read and accept the terms and conditions, and click Upgrade to confirm.
7. Once the hardware upgrade has started:
- The status will display 'Hardware upgrade in progress', and
- A notification will appear at the top of your screen. Click the bell icon to view.
