After upgrade, the customizations made on out of the box attributes are overridden and reset to the original.
Is there a way to not update out of the box attributes on upgrades?
Release : All Supported Versions
Component : CA PPM SAAS APPLICATION
Any changes made to out of the box assets will be overridden on any upgrade.
If you need a customized attribute, object, etc, you will need to create a new custom one instead of updating an out of the box one.
