Symptoms
An upgraded Confluence instance fails to start up and displays the following message:
Upgrade failed. Please consult the system logs for details. You will need to fix these problems, restore your database and confluence home directory to the pre upgrade state. Then retry the upgrade.
A similar error appears in the atlassian-confluence.log:

Cause
The instance you are attempting to upgrade has already had one upgrade attempt against it. What has happened is that the database has not been properly rolled back to the state prior to the original upgrade attempt which causes a conflict when creating new tables.
Resolution
Ensure that the home directory and database are returned to the state from before the original upgrade attempt.
