I am importing issues from Rally. In Rally, many of my issues are already assigned an iteration (Sprint). I have tried mapping the field from my csv to Sprint and get the error and when importing I am getting the error "Sprint ID must be a number:". My CSV has the name of the sprint such as 6.1.1 Iteration.
I tried creating the same iteration in Jira and mapping, got the same error.
Thoughts on how to solve this?
