Schedule a Compatibility Upgrade for a Single Virtual Machine
The compatibility level determines the virtual hardware available to a virtual machine, which corresponds
to the physical hardware available on the host machine. You can upgrade the compatibility to make the
virtual machine compatible with the latest version of the host.
To schedule an upgrade for multiple virtual machines, see “Schedule a Compatibility Upgrade for Virtual
Machines,” on page 247.
Prerequisites
n
Create a backup or snapshot of the virtual machines.
n
Upgrade to the latest version of VMware Tools. On Microsoft Windows virtual machines, if you
upgrade the compatibility level before you upgrade VMware Tools, the virtual machine might lose its
network settings.
n
Verify that all .vmdk files are available to the ESX/ESXi host on a VMFS-3, VMFS-5, or NFS datastore.
n
Verify that the virtual machine is stored on VMFS-3, VMFS-5 or NFS datastores.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, expand Upgrade and select Schedule VM Compatibility Upgrade.
3 Select the compatibility from the drop-down menu.
The virtual machine compatibility is upgraded the next time you restart the virtual machine.
4 (Optional) To upgrade the compatibility when you do regularly scheduled guest maintenance, select
Only upgrade after normal guest OS shutdown.
The virtual machine compatibility is upgraded and the new version appears on the virtual machine
Summary tab.
Determine the Default Virtual Machine Compatibility Setting in the

The compatibility setting for a virtual machine provides information about the hosts, clusters, or data center
that the virtual machine is compatible with.
The virtual machine Summary tab displays the compatibility for the virtual machine. You can set and view
the default compatibility that is used for virtual machine creation at the host, cluster, or datacenter level.
Procedure
u
Select an inventory object and display the virtual machine compatibility.
Option Action
