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:
The Tenable application does not apply changes, function properly, and the upgrade fails, when you do not manually open, review, and resolve each individual skipped change, and/or only update the Resolution field of the Skipped Changes list to Reviewed and Reverted (or to another resolved value).
For more information, see Upgrade the Tenable Applications.
