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).
