Use migration with Storage vMotion to relocate a virtual machine’s configuration file and virtual disks while the virtual machine is powered on.

You can change the virtual machine’s execution host during a migration with Storage vMotion.

Ensure that you are familiar with the requirements for Storage vMotion. See Storage vMotion Requirements and Limitations.

Required privilege: Resource.HotMigrate

1

Right-click the virtual machine and select Migrate.

a

To locate a virtual machine, select a datacenter, folder, cluster, resource pool, host, or vApp.

b

Click the Related Objects tab and click Virtual Machines.

2

Select Change datastore and click Next.

3

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, but is zeroed out on demand at a later time 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 grow to the maximum capacity allocated to it.

4

Assign a storage profile from the VM Storage Profile drop-down menu. Storage profiles define the storage capabilities that are required by the applications running on the virtual machine.

5

Select the datastore location where you want to store the virtual machine files.

Option

Action

Store all virtual machine files in the same location on a datastore.

Select a datastore and click Next.

Store all virtual machine files in the same Storage DRS cluster.

a

Select a Storage DRS cluster.

b

(Optional) To not use Storage DRS with this virtual machine, select Disable Storage DRS for this virtual machine and select a datastore within the Storage DRS cluster.

c

Click Next.

Store virtual machine configuration files and disks in separate locations.

a

Click Advanced.

b

For the virtual machine configuration file and for each virtual disk, select Browse, and select a datastore or Storage DRS cluster.

c

(Optional) If you selected a Storage DRS cluster and do not want to use Storage DRS with this virtual machine, select Disable Storage DRS for this virtual machine and select a datastore within the Storage DRS cluster.

d

Click Next.

6

Review the information on the Review Selections page and click Finish.

vCenter Server moves the virtual machine to the new storage location. Event messages appear in the Events tab. The data displayed on the Summary tab shows the status and state throughout the migration. If errors occur during migration, the virtual machines revert to their original states and locations.
