My project requirement is that the parent and child relationship is as follows
Parent Issue Type Child Issue Type
Epic Feature
Feature Story
Story SubTask
In Issue type Hierarchy i need Epic at level 2, Feature at Level 1, Story at 0, Task also at 0, Subtask at -1.
Is it possible to change the Epic level to 2 and add anew issue type at level1.
If I make the change at my site of JIRA cloud Instance will it impact the issues of other projects in same instance.
In JIRA can we use the change only for particular project.
