I read the description differences between Jira Software vs. Jira Core. We plan to use (Cloud) Jira Software, as we will be running Sprints. Other teams don't have a need to use sprints, but we wanted to have some consistency in the Atlassian software licensing.
1. What does "Jira Core" have in functionality that "Jira Software" does not have? Is there any downside to simply standardizing on "Jira Software"?
2. Does Jira Core integrate with Confluence?
3. [Bonus Question :-)] Does "Jira Software" have some sort of hierarchy above the Roadmap functionality for Epics? For instance, tasks can be referenced in an epic. Can a series of epics be reference in some sort of (series of say) Program Increments?
Thank you.
