How can I upload epics, then stories tied to epics, then sub tasks tied to stories?

[Enosler1218]

I am trying to build a template that will allow me to upload epics and their corresponding stories and sub tasks. My Csv keeps failing. Has anyone done this before. Should I be doing these separate from one another. How do I make sure I am connecting the right stories to epics and right sub tasks to stories?

You need to generate a unique ID for each row in your CSV, and then use that ID to link parent/child.  E.g, 

ID, IssueType, Summary, ParentID

1, Story, "Test Story",,

2, Sub-task, "This is a sub-task", 1,
