Manually Upgrading an ESXi Installation
This section describes how to perform a manual upgrade of a VMware ESXi virtual machine. This procedure is
recommended only if you experience problems when taking snapshots of a virtual machine on an ESXi version
5.x or 6.x.
By default, W-ClearPass 6.6 comes with VMware Tools version 9.4.10.37835 installed in it. If you are going to
perform a manual VMware Tools upgrade, you must first verify that a version of W-ClearPass is already
installed.
To manually upgrade a VMware installation:
1. Power on the virtual machine and verify that W-ClearPass is installed on it. In the vSphere client, right-click
on the VM instance and select Guest > Install/Upgrade VMware Tools.
