Abstract
A method, apparatus, and system are provided for performing a migration of control over a processing element from an original software system to a replacement software system. A replacement software system in memory associated with an active processing element is configured while an original software system controls the active processing element. The replacement software system is prepared to take control of the active processing element when state information is communicated to it from the original software system. Control of the active processing element is transferred to the replacement software system by a migration manager. A virtual machine may be used to facilitate the transfer of control, by interfacing between the active processing element, the original software system and the replacement software system. The virtual machine and original software system may be deactivated once control is transferred.
