JIRA comes with a database integrity checker utility to help you identify and fix data inconsistencies, which can often occur as a result of the following:
Installing and uninstalling add-ons with custom fields and workflow modules
Direct database manipulation via custom applications and/or scripts
These inconsistencies can sometimes lead to workflow errors or even system crashes. In this recipe, we will look at how to correct these data inconsistencies.
Before you fix any errors found with the integrity checker utility, make sure you create a backup of your data.
