How can I update or delete labels not only from issue but from the whole project?

[zsoni]

I want to update some labels and delete extra labels from my current project. Please help me with that.

i haven't played with it in awhile but likely hasn't changed. First labels are system wide not project specific. to remove a label from the available list you must find all issues that have that label and remove the label from all of the issues.

We use label manager for JIRA Cloud. It takes all the pain out of managing labels:

You can't really do that in the way you might be thinking - but you can do this in a roundabout way.

There is no master control for labels - and you can't easily limit what labels can be created.
You can find all the labels used (macros for that in confluence), or you can find all the occurrences of a specific label or labels through JQL - then you can bulk add/remove them from those issues directly.
