Hi,
JIRA contains a issue type called "Sub Task" by default. It seems like we have accidentally created another subtask issue type called "Sub-task" (not the difference in names).
Now we want to delete the extra issue type "Sub-task" which was created but there are some sub tasks issues already existing with this issue type.
My question is how can we convert the issue type of these tasks from "Sub-task" (redundant) to "Sub task" (default) issue type?
Regards,
Zeeshan
