Abstract
Persistent data, such as disks associated with virtual machines, are migrated between and across data stores using mirrored input-output operations (IOs). The migration technique employs a data mover to copy selected regions of the virtual machine disk to a target data store while the virtual machine is executing. If the virtual machine issues a write IO, the write IO is selectively mirrored on the target data store depending on whether or not the write IO is in a region of the virtual machine disk that has already been copied.
