Operating system migration with minimal storage area network reconfiguration

摘要

Methods, systems, and computer program products are provided for migrating an operating system from a source computer to a destination computer. Some embodiments include identifying a destination adapter of the destination computer that is coupled for data communications to a SAN that is also coupled for data communications to a source adapter of the source computer, logging off a virtual port name of the source adapter from the login manager, deregistering the virtual port name from the source adapter, registering the virtual port name with the destination adapter, and logging on the destination adapter to the login manager with the virtual port name. Typical embodiments also include transferring the operating system from the source computer to the destination computer.
