Abstract
A system, computer program product and method for a running process migration with planned minimized down-time. The method facilitates fast and efficient process migration by performing background data synchronization prior to actual process migration. The service slowdown is reduced by employing two-stage transfer method. During a first stage the service, being executed on the original machine, does not stop and all the available data required by this process is being copied. After the first stage is completed the service continues to be executed without an interruption, while the most of the data associated with the service process is already transferred to the new machine. During the second stage the execution of the service on the first machine is stopped. The files, which were not available during the first stage, are now copied. Then the execution of service is started on the second machine. The down-time is reduced to the duration of the second stage.
