Check prerequisites

In SA, prerequisite checking is automated. This check occurs before upgrade begins and verifies that all necessary packages/patches are installed on your system, as well as verifying certain environmental conditions (diskspace, locales, required directories, and so on). Most checks are advisory, not mandatory. If a prerequisite condition is not met by your system, you will see a warning and can either stop the upgrade to mitigate the problem or continue the upgrade.

If a required package is not installed on any machine that will host an SA Core Component, you must install the package before performing the upgrade.

For more information about required packages, see the SA Install section.
