I've been left with a JIRA project in a questionably maintained system that's something of a mess. This project has over 50 issue types, of which only 6 are used.
How do I update the project configuration to disable the unused issue types? I've clicked everywhere I can think of in the project settings and I don't see any clue here.
Does Atlassian provide documentation on this? Why is it not something that is linked from a relevant project configuration page?
