Abstract
Method, computer program product, and computer system are provided. A first migration of a running logical partition (LPAR) is performed from a first-generation computer to a second-generation computer. Availability of a facility differs between the first- and second-generation computers. Upon completion of the first migration, an operating system of the running LPAR detects whether a required facility in use on the first-generation computer is available on the second-generation computer. Operating system takes an action to continue an orderly execution of the LPAR, the operating system, and threads of an application in the LPAR depending on the availability of the required facility. A second migration is performed of the running LPAR from the second-generation computer back to the first-generation computer. The required facility is available on the first-generation computer. The operating system restores access to threads of the application to the required facility.
