An implementation engineer needs to perform an upgrade of IdentityIQ between releases.

No. Custom branding changes should not be assumed to update automatically during an IdentityIQ upgrade. Branding changes often involve customized UI resources, message files, images, CSS, JSPs, configuration entries, or other web-application artifacts. During an upgrade, the standard IdentityIQ application files are replaced or changed, and customizations may need to be re-applied, merged, retested, or adjusted to align with the new release. Assuming the upgrade process automatically updates every custom branding change is a bad implementation practice. Engineers should inventory all customizations before upgrade, compare them against the new release, reapply supported changes, and validate the UI after deployment. This also applies to broader customizations such as rules, workflows, Quicklinks, forms, libraries, object extensions, and localized messages. The correct upgrade discipline is controlled migration and regression testing, not blind reliance on automatic preservation.
