The problem
A query like updated < startOfDay() matches different issues a minute later. Native bulk edits also leave you to work out which issues failed and why.
Step by step
- Bulk operations. Enter the JQL and preview. Read the match count and the sample of issue keys.
- Choose the operation: add label, set a field, transition, move or delete, and confirm.
- Read the per-issue result. A partial result across mixed projects is normal; the reasons come from Jira.
What to watch out for
The run acts on the issues the preview resolved, not on a re-run of the query. For delete or move, a match larger than 1,000 is refused outright rather than acted on in part: narrow the query by project, date or issue type until it fits.
