Summary
This article introduced and reviewed LU, and provided techniques and best practices for LU usage. LU is a valuable tool that provides a mechanism for upgrading the Solaris OE with minimal downtime. Further, LU enables large scale changes to the Solaris OE with minimal impact to the user or applications. Most importantly, LU provides a safe and consistent fall-back environment in case an upgrade or software installation fails.
