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

Display the virtual machine 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 resource pool and click Next.

5

Select the destination datastore.

To move the virtual machine configuration files and virtual disks to a single destination, select the datastore and click Next.

To select individual destinations for the configuration file and each virtual disk, click Advanced. In the Datastore column, select a destination for the configuration file and each virtual disk, and click Next.

6

Select a disk format and click Next:

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.

Disks are converted from thin to thick format or thick to thin format only when they are copied from one datastore to another. If you choose to leave a disk in its original location, the disk format is not converted, regardless of the selection made here.
