Common Reasons for Failed Upgrade
Not Reviewing Skipped Changes
If you do not review the Skipped Changes after an upgrade, the apps will not work properly and the upgrade will be unsuccessful.
Incorrectly Reviewing Skipped Changes
If you do not manually open, review, and resolve each individual skipped change, and only update the Resolution field of the Skipped Changes list to “Reviewed and Reverted” (or to another resolved value), no changes will be applied, the apps will not work properly, and the upgrade will fail.
