Before you Begin

A virtual disk copy fails all snapshot virtual disks that are associated with the
target virtual disk, if any exist. If you select a source virtual disk of a snapshot
virtual disk, you must disable all of the snapshot virtual disks that are
associated with the source virtual disk before you can select it as a target
virtual disk. Otherwise, the source virtual disk cannot be used as a target
virtual disk.
A virtual disk copy overwrites data on the target virtual disk and automatically
makes the target virtual disk read-only to hosts
If eight virtual disk copies with a status of In Progress exist, any subsequent
virtual disk copy has a status of Pending, which stays until one of the eight
virtual disk copies completes.

Virtual Disk Copy and Modification Operations

If a modification operation is running on a source virtual disk or a target
virtual disk, and the virtual disk copy has a status of In Progress, Pending, or
Failed, the virtual disk copy does not take place. If a modification operation is
running on a source virtual disk or a target virtual disk after a virtual disk copy
has been created, the modification operation must complete before the
virtual disk copy can start. If a virtual disk copy has a status of In Progress, any
modification operation does not take place.

Create Copy Wizard

The Create Copy Wizard guides you through:
1 Selecting a source virtual disk from a list of available virtual disks
2 Selecting a target virtual disk from a list of available virtual disks
3 Setting the copy priority for the virtual disk copy
When you have completed the wizard dialogs, the virtual disk copy starts, and
data is read from the source virtual disk and written to the target virtual disk.
