Abstract
The present invention discloses a method, apparatus, and article of manufacture for version migration and fallback of software components in a computer system. The invention creates alternate boot environments that preserve the state of all original software components on a system before performing a software upgrade. The invention virtually eliminates the risks of migrating to upgraded system because users can quickly fall back to a previous operating environment, without extended downtime during and after upgrades.
