I am importing a MS Project program into Jira. Because there are so 9 hierarchy levels to the program, I need to know what issue types that Roadmaps will support. I need to know the levels starting from the top going down. If possible, I want to avoid using sub task in the plan since this will affect another project that would be mapped into the plan.
Starting from the top, what would be the 9 levels I can incorporate and manage my project in the plan?
Any help would be greatly appreciated!
