The Upgrade Analysis is one of the key features of the assurance service that will help with the upgrade when there is a major or standard IDMC release and identify the impact of the upgrade on the user's organization. Upgrade Analysis helps users identify the assets that are impacted because of the upgrade, thus helping users form a regression test suite that they can use effectively to test it in a pre-release environment.
