Patent ID: 8713139

Claim:
A method for automatically reconfiguring a computer network in response to an operating system image migration from a first hardware platform to a second hardware platform, the method implemented on a suitably programmed device, comprising: detecting a boot up command and in response: automatically applying an old network configuration for the migrated operating system image; initializing a fix up utility, creating a new network configuration for the migrated operating system image, and wherein the network configurations are created by a plug and play utility that uses dynamic host configuration protocols; storing the new network configuration information; reading, by the fix up utility, the new network configuration information and old network configuration information corresponding to the first hardware platform; determining, by the fix up utility, if any of the new network configuration information corresponds to a new network interface controller and if any of the old network information corresponds to a non-assigned network interface controller; and if any of the old network configuration information corresponds to a non-assigned network interface controller, reassigning network interface controller identifiers from the old network configuration information to the new network interface controller; wherein the reassigning is contingent on the migration occurring between a virtual machine to a physical machine, or occurring between a virtual machine to a virtual machine.
