We have JIRA cloud and on our service project board there are a lot of template options. We're looking to consolidate and create 3 standard templates and delete the old ones. Optimally, we'd like to just hide them or mark them not in use but that seems to not be an option. My concern is if we delete them, what happens to the thousands of closed tickets? Those that are open, we can move to a different type, however there are way too many closed for that. Also, we want to make sure we don't lose any of that historical information.
