US Patent 8713139 Automatic fixup of network configuration on system image move

A method and device provide 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 includes detecting a boot up command and in response, initializing a fix up utility, creating a new network configuration for the migrated operating system image and storing the new network configuration information; reading the new network configuration information and old network configuration information corresponding to the first hardware platform; determining 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.
