If an app in the QMC App section has a migration status of Unknown, what action should the admin take?

When an app in the Qlik Management Console (QMC) has a migration status labeled as Unknown, it indicates that the system cannot determine the current state or compatibility of that app with the existing environment. This can happen for several reasons, such as the app being created in an older version of Qlik Sense or facing issues during the last migration process.

To resolve this status, the appropriate action is to migrate the app. By migrating the app, the admin can ensure that it is updated to the current environment standards and settings, bringing it in line with the latest version and features of Qlik Sense. This action allows the app to function properly and helps in maintaining data integrity and compatibility with any new features or configurations that may have been introduced since its last update.

Other actions like publishing the app or re-importing it would not address the underlying migration status and might not ensure the app functions correctly with the latest Qlik Sense features. Additionally, deleting the app would result in loss of data and configurations, which would not resolve the issue at hand. Therefore, migrating the app is the best course of action when faced with an Unknown migration status.
