Abstract

Software, firmware, and systems are described herein that migrate functionality of a source physical computing device to a destination virtual machine. A non-production copy of data associated with a source physical computing device is created. A configuration of the source physical computing device is determined. A configuration for a destination virtual machine is determined based at least in part on the configuration of the source physical computing device. The destination virtual machine is provided access to data and metadata associated with the source physical computing device using the non-production copy of data associated with the source physical computing device.

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;

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.

2. The computer-readable storage medium of claim 1, wherein the migration method is initiated in response to determining that the source physical computing device has lost some of its data redundancy protection or a disk drive, or the source physical computing device has been infected by a virus.

3. The computer readable storage medium of claim 1, wherein the method is initiated in response to determining that the source physical computing device has experienced an increase in frequency of errors or in response to determining that the source physical computing device has presented symptoms indicative of system instability.

4. The computer-readable storage medium of claim 1, further comprising updating existing IP address mapping from the source physical machine to the destination virtual machine;

and, applying existing information management policies from the source physical machine to the destination virtual machine.

5. The computer-readable storage medium of claim 1, wherein the virtual machine is created by repurposing an existing virtual machine, and further comprising using another snapshot to revert the virtual machine to an earlier point in time, wherein the virtual machine has a physical compatibility mode raw device mapped logical unit number (LUN).

6. The computer-readable storage medium of claim 1, further comprising performing information management operations on the production data of the destination virtual machine;

restoring or otherwise providing production data to the destination virtual machine from a non-production copy of the data; and

installing application binaries to the destination virtual machine based on applications determined on the source physical computing device.

7. The computer-readable storage medium of claim 1, wherein modifying the configuration of the virtual machine based at least in part on the determined configuration for the destination virtual machine comprises adjusting the configuration of the virtual machine to match the determined configuration using, at least in part, one-touch recovery techniques.

8. The computer-readable storage medium of claim 1 wherein a DNS table, routing table or similar data structure is updated with the IP address, so that the table points to the IP address of the destination virtual machine instead of pointing to a previous IP address associated with the source physical computing device.

9. A method for migrating functionality of a source physical computing device to a destination virtual machine, the method being performed by a processor executing instructions stored in a memory, the method comprising:

determining a configuration of the source physical computing device;

determining a configuration for a destination virtual machine based at least in part on the configuration of the source physical computing device;

providing the destination virtual machine with access to data and metadata associated with the source physical computing device using a non-production copy of data associated with the 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;
