I've been trying out plugins to manage start/end dates of Jira Work Item tasks, in order to track timely delivery of releases as well as manage dependencies. I guess what I'm looking for is something that works on similar lines to 'leveling' in Microsoft Project. I have tried several 'Gantt' plugins, and plugins for import/export between Jira and MS Project, to no avail. Ultimately it appears I need to manually change start/end dates individually across thousands of tasks per release.
I am interested in the plugin 'Structure' and will review that next. However it doesn't appear to actually manage issues, merely display a heirarchy. I am interested if anyone can offer other solutions to this.
