1. At least one tangible non-transitory computer-readable storage medium storing instructions, which when executed by at least one data processing device perform a method for migrating functionality of a source physical computing device to a destination virtual machine, the method comprising: identifying a non-production copy of data and metadata associated with a source physical computing device, wherein the non-production copy is stored on one or more non-production storage media separate from the source physical computing device and separate from the destination virtual machine, determining a configuration of the source physical computing device; determining or establishing a desired configuration for a destination virtual machine, wherein the configuration is based at least in part on the determined configuration of the source physical computing device; creating a virtual machine based on the determined configuration of the source physical computing device; providing the virtual machine with access to the one or more non-production storage media to thereby access the data and metadata from the non-production copy of data and metadata associated with the source physical computing device, wherein the data and metadata from the non-production copy includes application-specific data and metadata; modifying a configuration of the virtual machine based at least in part on the determined or established configuration for the destination virtual machine, wherein modifying the virtual machine comprises modifying a configuration of the virtual machine to substantially match the determined or established configuration for the destination virtual machine; following the modifying, updating a mapping of an IP address of the source physical computing device, the destination virtual machine, or both the source physical computing device and destination virtual machine, such that client computing devices are directed or routed to the destination virtual machine instead of the source physical computing following the modifying, and such that, the source physical computing device is decommissionable after migration is complete, and wherein the source physical computing device is inoperable after being decommissioned; and disposing of the source physical computing device following decommissioning, including permanently wiping data and metadata stored on the source physical computing device, and notifying a server associated with an intranet site or auction site that the source physical computing device is available for use by other users in an organization or for sale to external parties, wherein the notification includes a description or specification of the source physical computing device.
