About the preUpgradeChecks Script
This release includes a preUpgradeChecks script that validates your system for
upgrade eligibility. The preUpgradeChecks script should be run 2 or more weeks
prior to your upgrade in order to ensure that enough time exists to resolve any major
issues or incompatibilities that may affect your ability to upgrade.
The preUpgradeChecks script should be run again just before you upgrade to
validate the system. The instructions are found in Run the preUpgradeChecks Script
on the DNCS and RNCS to Migrate to an Integrated Application Server (on page
37).
Important: The preUpgradeChecks scripts must be run on each server that will be
upgraded (for example, DNCS, Application Server, RNCS).
