Editing Issues
Issues are typically updated during the lifetime of a project. Users with different roles like project manager, architect, developer, or contractor can change the status, priority, and severity of issues based on their roles and permissions. For example, customers can submit a bug, but can view only the bugs that were submitted by them. A support engineer can view and edit all bug submissions, then assign them to one or more developers, and later a test engineer can close the issue.
Issues can be edited using in-place edit on the issue details page. A double-click on a field starts the in-place editor of the field. The description field has a

When a user starts editing an issue, it automatically gets locked for other users. The other users can see a notification in the issue breadcrumb.

Using Cut, Copy, and Paste (Move and Duplicate)
With Cut, Copy and Paste options you can easily Duplicate and Move issues across trackers and projects.
Copying Issues With Copy and Paste
You can copy existing issues into a different tracker in either the same project or in a different project. When the source and the destination tracker have different fields, a field mapping wizard helps associate the different fields. When the copy or paste commands are used, the duplicate issues are dependent on the source issue.Mass Edit feature enables removal of this dependency.
Copy and Move Issues Between Trackers
Reorganizing projects may require moving issues into different trackers. For example, move a change request entry into a task tracker. When the source and the destination trackers are different, the field-mapping wizard allows easy mapping of the source and destination fields.
You can use thhe actions Copy to and Move tooption to copy and move selected issues from one tracker to another tracker. Under the Children tab of an issue, you can select children of an issue and similarly copy or move, using the Extra action

The possible target trackers are grouped by project and optionally, you can filter them by type.
During Move To and Copy To operations, you can select an item of the target tracker in the Parent field. After copying the items the selected item becomes their parent.
