Bamboo 3.2 Upgrade Fails on UAL Upgrade Task
Bamboo 3.2 upgrade fails due to mis-configured JIRA integration.
UpgradeTask 2511 converts existing JIRA server configuration to UAL config. If the upgrade is stuck on this upgrade task, you can delete the JIRA mapping manually and re-establish AppLinks after upgrading.
To delete your JIRA mapping execute the following SQL on your database;
DELETE * FROM JIRASERVER
You don't have to restore Bamboo from backup, you can re-run the upgrade by restarting Bamboo.
