Each ESXi host comes with it’s own VM Hardware Version which defines the maximum configuration supported for Virtual Machine. For Example how much maximum Hard disk you can use with VM, How much maximum CPU you can assign to VM etc etc. So in this post we will see on How you can Upgrade VM Hardware using VMware Update Manager.
Update Manager allows you to Upgrade VM Hardware version as well using the VMware Update Manager UI. So now you can easily Upgrade VMware Hardware versions. It is necessary to go for VM Hardware Upgrade after ESXi Upgrades so to use the full functionality of the Supported features on Virtual Machine & run VMs efficiently.
