A method and apparatus is described herein for performing parallel memory migration, as well as execution of management tasks over a plurality of management window. Handlers are dispatched to multiple resources, such as cores or threads, to determine a proper memory migration handler. Each resource, during a management mode, executes a designated memory migration handler or an instance of a memory migration handler to perform a portion of a memory migration task in parallel. A task data structure is capable of supporting tracking of portions of memory migrated. In addition the task data structure is potentially also capable of tracking management tasks through plurality of management windows to support servicing of management tasks through multiple management windows.
