We are using Jira Data Center to manage a project using a Feature => Story => Task Hierarchy. I'd like to set up automation so that when all children (stories in this case) are all marked done by the agile team, then Jira will automatically change the status of the parent feature (in our case Validating on Stage is the next status in our ART kanban). Seen lots of variations on using Epics and even Stories with Tasks. Wonder if anyone else has experience doing this?
