Downloading the PeopleTools Upgrade Change Package
You may either download the PeopleTools upgrade Change Package from the PeopleTools upgrade page on My Oracle Support, or use the PeopleTools upgrade Change Package that was delivered when deploying the PeopleTools DPK for your new release. Additionally, you may find it useful to download a PDF copy of the upgrade documentation from the Install and Upgrade section on the PeopleSoft PeopleTools page of the Oracle Help Center.
