Hello,

You should add workflow property to the Done status:

jira.issue.editable = false

It depends on your role in Jira, workflow and platform that you are using (Cloud or Server). If using simplified worflow it might be not possible. You would need to have a workflow that have clearly defined transitions (not all to all) then you might block those that are going from DONE to previous statuses.

You could simply remove all outgoing transitions on the status DONE.
