@jetersen developed this awesome javascript to delete all deletable, inactive workflows in JIRA.
- As admin, go to https://jira/secure/admin/workflows/ListWorkflows.jspa
- Open developer console in your browser, copy paste the js below and run it.
It may crash your browser, but not JIRA.
Tested on our instance:
- Removed 125++ inactive workflows
- Via Google Chrome 74.0.3729.131
- On JIRA 7.10.2
Awesome, thanks for this!
