Understanding Change Assistant For Upgrades
Application upgrade only applies to upgrading an older application release to application release 9.2. Once your application is on 9.2, PUM is used to apply maintenance and new features. You use Change Assistant to help automate and customize the PeopleSoft upgrade process. A PeopleSoft upgrade typically includes a PeopleTools and a PeopleSoft application upgrade.
Depending on your upgrade path, the application upgrade may be combined with the tools upgrade. If they are not combined, you will need to perform the tools upgrade before the application upgrade.
The following list describes the major steps within an upgrade when using Change Assistant.

With the release of PeopleSoft PeopleTools 8.56, deployment packages (DPKs) are being used for the Upgrade Source Images. Each PeopleSoft application upgrade home page in My Oracle Support includes a tab for the Upgrade Source Images for that application.
