On an existing set of issues i need to update data in two new custom fields created. Can I upload?
I have some old issues which I recently migrated to JIRA. I need to add the legacy creator and creation date, for which I have created custom fields. These are 100+ issues already created. I want to further add these two values on it. How to add through upload? I dont want to manually add on each of the 100+ issue.
Please recommend.
