Is there a way to get usage statistics for JIRA workflows, Field schemes, Issue Types schemes, Screen schemes and custom fields. We are planning to upgrade and do not wantto include schems & custom fields NOT USED. What kind of report is avilable or used for internal JIRA developers? Any script we can run against Oracle database that can give us usage statistics? Example: How many times a custom field has been populated, workflows not used in any project? Schemes not used in any project?
