One of the first steps that should be taken prior to an Oracle Database Upgrade is determining any issues the upgrade may present to your database.
Oracle Database Pre-Upgrade utility is executed on your existing database, while the database is running (no shutdown required) and provides a list of items which should be reviewed prior to the actual upgrade. Reviewing and making adjustments prior to actual database upgrade will usually reduce down time and can limit problems during the upgrade.
Origin of Script
The pre-upgrade scripts that are available for download below are shipped with each Oracle Database release. The scripts can also be found in the newly installed $ORACLE_HOME/rdbms/admin directory of the version you are planning to upgrade to. Getting a hold of the pre-upgrade script used to mean downloading the entire Oracle Database Release kit, unpacking it, and pulling it out of the admin directory. Allowing access to the script through this method will make the Oracle Database Upgrade planning easier.
