Abstract
A system for image upgrade, according to one embodiment of the present invention comprises an upgrade director and a target device comprising a manager module.

The manager module downloads an upgrade image after the delay parameter has ended. The upgrade director sends a second command to the manager module indicating that the upgrade event is to conclude. The manager module receives the second command from the upgrade director. The manager module reboots using the upgrade image responsive to the second command.
