Upgrade and patch management layer – vCenter Update Manager 6.5

vCenter Update Manager (VUM) is a solution that is used to upgrade or patch your vSphere environment. Keep in mind though that it can only be used to patch/upgrade ESXi hosts and perform some additional tasks, such as VMware tools and virtual machine hardware upgrade. Starting with vSphere 6.5, VUM is no longer required to be installed on Windows machines. It is now fully integrated into the vCenter Appliance and is enabled by default. Also, its reliance on the vSphere C#-based client has been removed. It can now be fully operated using the vSphere Web Client. You will learn more about VUM in Chapter 14, Upgrading and Patching Using vSphere Update Manager.
