I've inherited a JIRA with that people have been poking at for seven years, with dozens of obsolete projects, workflows, etc. and thousands of tickets. For example, I'm having trouble setting up a Kanban board, because too many issues get pulled in by default. I've never administered JIRA before, so I'm groping my way through the complicated configuration and 'it depends' documentation.
Can anyone recommend a guide to paring down a JIRA that hasn't been managed well?
A test project sounds like an excellent way to understand the options!
Are there any tools for closing all issues that haven't been touched in the last six months?
you can only use JQL to search for issues that didn't have a change. I'm not a JQL expert so I use google a lot and trial and error until I get it.
once you're able to filter the issues you want, you can then use option for bulk update. It's at the top right corner of the screen when you search for issues.
of course, you must have admin rights.
