We have created a series of issues using the child feature for a Story in next-gen. We realize that the child issues were all created as subtasks and we want to change them all to task types of Issues. Bulk edit and move issue do not allow this to happen nor can we click on the subtask in the key and be shown a task issue type as being available.
How do we perform this conversion or change from subtask to task issue type and keep in the existing issue of story?
