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

You cannot change the virtual machine’s execution host during a migration with Storage vMotion.

1

Select the virtual machine that you want to migrate in the inventory.

2

Right-click on the virtual machine and select Migrate from the pop-up menu.

3

Select Change datastore and click Next.

4

Select a disk format.

Option

Description

Same as Source

Use the format of the original virtual disk.

If you select this option for an RDM disk in physical compatibility mode, only the mapping file is migrated. If you select this option for an RDM disk in virtual compatibility mode, the RDM is converted to a virtual disk.

Thin provisioned

Use the thin format to save storage space. The thin virtual disk uses just as much storage space as it needs for its initial operations. When the virtual disk requires more space, it can grow in size up to its maximum allocated capacity.

This option is not available for RDMs in physical compatibility mode. If you select this option for a virtual compatibility mode RDM, the RDM is converted to a thin virtual disk. RDMs converted to virtual disks cannot be converted back to RDMs.

Thick

Allocate a fixed amount of hard disk space to the virtual disk. The virtual disk in the thick format does not change its size and from the beginning occupies the entire datastore space provisioned to it.

This option is not available for RDMs in physical compatibility mode. If you select this option for a virtual compatibility mode RDM, the RDM is converted to a virtual disk. RDMs converted to virtual disks cannot be converted back to RDMs.

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.

a

(Optional) Apply a virtual machine storage profile for the virtual machine home files and the virtual disks from the VM Storage Profile drop-down menu.

The list of datastores shows which datastores are compatible and which are incompatible with the selected virtual machine storage profile.

b

Select a datastore and click Next.

Store all virtual machine files in the same datastore cluster.

a

(Optional) Apply a virtual machine storage profile for the virtual machine home files and the virtual disks from the VM Storage Profile drop-down menu.

The list of datastores shows which datastores are compatible and which are incompatible with the selected virtual machine storage profile.

b

Select a datastore cluster.

c

(Optional) If you 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 datastore cluster.

d

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, click Browse and select a datastore or datastore cluster.

c

(Optional) Apply a virtual machine storage profile from the VM Storage Profile drop-down menu.

The list of datastores shows which datastores are compatible and which are incompatible with the selected virtual machine storage profile.

d

(Optional) If you selected a datastore 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 datastore cluster.

e

Click Next.
