Abstract

Software, firmware, and systems are described herein that migrate functionality of a source physical computing device to a destination physical computing device. 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 physical computing device is determined based at least in part on the configuration of the source physical computing device. The destination physical computing device 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.
