Before you upgrade the virtual hardware:
– Create a backup or snapshot of the virtual machine.
– Upgrade VMware Tools. On Microsoft Windows virtual machines, if you upgrade the virtual hardware before you upgrade VMware Tools, the virtual machine might lose its network settings.
– Verify that all .vmdk files are available to the ESXi/ESX hosts on a VMFS 3, VMFS 5, or NFS datastore.
– Verify that the virtual machines are stored on VMFS 3, VMFS 5 or NFS datastores.
