If your environment has more than one vCenter Server instances, you can move virtual machines
from one vCenter Server inventory to another.
Important If the virtual machine that you migrate has an NVDIMM device and virtual PMem hard
disks, the destination host or cluster must have available PMem resource. Otherwise, the
compatibility check fails and you cannot proceed further with the migration.
If the virtual machine that you migrate does not have an NVDIMM device, but it has virtual PMem
hard disks, the destination host or cluster must have available PMem resource, so that all PMem hard
disks remain stored on a PMem datastore. Otherwise, all the hard disks will use the storage policy
and datastore selected for the configuration files of the virtual machine.
Important Migrating a virtual machine that has an NVDIMM device or a vPMem disk to a host that
does not have the proper license fails and leaves the virtual machine in an unmanageable state for 90
seconds. You can afterwards retry the migration and choose a destination host that is licensed to use
PMem devices.
4 On the Select storage page, select the storage type for the virtual machine configuration files and all
the hard disks.
n
If you select the Standard mode, all virtual disks are stored on a standard datastore.
n
If you select the PMem mode, all virtual disks are stored on the host-local PMem datastore.
Configuration files cannot be stored on a PMem datastore and you must additionally select a
regular datastore for the configuration files of the virtual machine.
n
If you select the Hybrid mode, all PMem virtual disks remain stored on a PMem datastore. Non-
PMem disks are affected by your choice of a VM storage policy and datastore or datastore
cluster.
5 Select the format for the virtual machine's disks.
Option Action
Same format as source Use the same format as the source virtual machine.
Thick Provision Lazy Zeroed Create a virtual disk in a default thick format. Space required for the virtual disk is
allocated during creation. Any data remaining on the physical device is not erased
during creation. Instead, it is zeroed out on demand on first write from the virtual
machine.
Thick Provision Eager Zeroed Create a thick disk that supports clustering features such as Fault Tolerance.
Space required for the virtual disk is allocated at creation time. In contrast to the
thick provision lazy zeroed format, the data remaining on the physical device is
zeroed out during creation. It might take longer to create disks in this format than
to create other types of disks.
Thin Provision Use the thin provisioned format. At first, a thin provisioned disk uses only as much
datastore space as the disk initially needs. If the thin disk needs more space later,
it can expand to the maximum capacity allocated to it.
