Ticket Status

how to do change an abandoned status to implementing?

[Nic Brough -Adaptavist-]

Do you mean

An issue's current status?  If so, then you will need to use a transition from "abandoned" to "implementing" (also represented by you dragging the issue card between columns if you're looking at a board rather than the plain issue view)

or

The name of the status?  If this, then log in as an admin and go to Admin -> Issues -> Status and edit the name.  Be aware that this will affect all workflows that currently use that status.
