6 Select the migration priority level and click Next.
Option Description
High Priority
On hosts running ESX/ESXi version 4.1 or later, vCenter Server attempts to
reserve resources on both the source and destination hosts to be shared
among all concurrent migrations with vMotion. vCenter Server grants a
larger share of host CPU resources to high priority migrations than to
standard priority migrations. Migrations always proceed regardless of the
resources that have been reserved.
On hosts running ESX/ESXi version 4.0 or earlier, vCenter Server attempts
to reserve a fixed amount of resources on both the source and destination
hosts for each migration. High priority migrations do not proceed if
resources are unavailable.
Standard Priority
On hosts running ESX/ESXi version 4.1 or later, vCenter Server reserves
resources on both the source and destination hosts to be shared among all
concurrent migration with vMotion. vCenter Server grants a smaller share
of host CPU resources to standard priority migrations than to high priority
migrations. Migrations always proceed regardless of the resources that
have been reserved.
On hosts running ESX/ESXi version 4.0 or earlier, vCenter Server attempts
to reserve a fixed amount resources on the source and destination hosts for
each migration. Standard priority migrations always proceed. However,
the migration might proceed more slowly or fail to complete if sufficient
resources are not available.

A task is created that begins the virtual machine migration process.
Migrate a Virtual Machine with Storage vMotion in the vSphere Client
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.
Procedure
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.
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 expand up to its maximum allocated
capacity.
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.
