Customization Repository on the PUM Source
Since the release of PeopleSoft’s 9.2 applications and PeopleTools 8.53, PeopleSoft Update Manager has been used to selectively choose patches and new functionality to apply to your existing PeopleSoft environments. Using Update Manager, administrators can search and select desired updates and allow the tool to build a comprehensive package which includes all necessary prerequisites and excludes updates which require a higher PeopleTools release than is available on the target environment. But if the PUM Instance is on a different database platform and/or PeopleTools release from the target, a compare using Application Designer cannot be run so you need another way to identify potential conflicts with customized objects prior to creating and exporting the change package. This is the function of the Customization Repository.
