The final removal started July 13 and completes by July 26, 2026, rolling out through Jira's seasonal releases. If you're reading this and your instance still opens the old editor, you're in the last wave, and there are a few things that fail quietly rather than loudly when it flips.
I've spent the last few months moving client instances (and my own app's workflow rules) fully onto the new editor. This isn't a feature tour. Atlassian's announcement already covers "what's changing." This is the list of things that actually bit, in order of how much they'll hurt.
Updated 21st July:
Clarified how common transitions appear in the new editor (nothing is merged; your data doesn't change), and added a sixth check from the comments: the new editor has no XML export, so snapshot your workflows via API before the flip. Thanks to @Becker_ Rene, @Derek F_, @Antonio Valle _G2_ and @Aaron Morris for sharpening this post.
Scope note: this is Jira Cloud only. Data Center keeps its editor, so nothing here applies to DC.
1. Unpublished drafts are the silent killer
The new editor has no draft concept. It edits the active workflow directly. The old editor's drafts don't carry over. Worse: if a workflow still has an old-editor draft sitting on it, edits made in the new editor can fail to apply to transitions, or you'll get stale-draft warnings where publishing the old draft would overwrite newer changes. This is tracked as JRACLOUD-83818.
The fix, before July 26: audit every workflow for unpublished drafts and either publish or discard them. All of them. A draft someone parked in 2024 "to finish later" is now a data-loss risk, because once the old editor is gone, that draft's changes are unrecoverable through the UI.
Quick way to find them: Settings (gear icon) > Issues > Workflows. Drafts are flagged in the workflow list. In larger instances, split the list among your admin team and clear it this week.
2. "Common transitions" don't exist anymore. The model changed.
In the old editor, you reused a transition across statuses by creating it once and applying it to other statuses via Add transition. The new editor replaces this with a single transition that can originate from multiple statuses, carrying one set of rules and properties.
Functionally equivalent for most workflows. But if your old workflow used the reuse pattern with slightly different rule sets on what looked like the same transition, the consolidation is where behaviour drifts. After the flip, open your three most complex workflows and verify each multi-origin transition's rules against what you had. Do it while your old-editor documentation and screenshots are still fresh.
3. Your automation for transition properties may already be broken
Separate from the editor, but it lands in the same cleanup: the workflow transition properties API set has been removed from the public API (deprecated March 30, 2025, now gone). If you have scripts, CI checks, or admin tooling that read or wrote jira.permission.* or other transition properties through those endpoints, they're failing now. The replacement is the Bulk get workflows and Bulk update workflows APIs.
Transition properties themselves still exist and are editable in the new editor (select the transition, then properties in the details panel). It's the old API surface that's gone, not the feature. I've seen these confused in at least three Community threads.
4. Rules moved and got renamed. Retrain the muscle memory before the tickets arrive.
Conditions, validators, and post functions are all "rules" now, configured from the transition's details panel in the single-view editor. No more separate tabs. Atlassian publishes a mapping table of old rule names to new ones ("Features in the new workflow editor" in support docs); print it, because the first week of admin questions will be "where did the Field Required validator go," and the answer is "same rule, new name, new location."
One thing that's better than the rumors suggest: the new editor does have a text view for complex workflows. Atlassian lists it explicitly in the deprecation notice. If you've been holding onto the old editor because "the new one has no text mode," that reason expired. Use it for search-and-debug on your spaghetti workflows.
What is still being raised by admins in the comments of Atlassian's own deprecation post: confusion over how conditions/validators/post functions were remapped, and concerns about approval restrictions and rule-ordering behaviour under the new rule structure. If your workflows lean heavily on approvals or on precise rule execution order, test those specific paths on a copy of a real workflow this week, not after the 26th.
5. If you run workflow apps (JSU, ScriptRunner, JWT, or anything from the Marketplace), test that the rules render
Wearing my app-developer hat for a moment: Atlassian's guidance to vendors is that workflow-related apps must provide their rule configuration properly inside the new editor, ideally with dynamic rule descriptions so admins can read what a rule does at a glance. Most major vendors are ready, but "ready" varies. In one migration I found an app's post function that configured fine but showed a blank description in the new editor, which meant the admin team couldn't audit workflows without opening every single rule.
The test open a workflow that uses app-provided rules, confirm every rule (a) opens its config panel, (b) saves, and (c) shows a meaningful description in the diagram view. Atlassian recently added the ability to preview marketplace transition rules in the new editor, with a "View all" rules experience on the way. The platform side is improving, but the description quality is still on each vendor. If anything fails, raise it with the vendor now; after the 26th there's no fallback editor to hide in.
The pre-July-26 checklist
- Publish or discard every old-editor draft (this is #1 for a reason)
- Screenshot or export your most complex workflows for reference before the flip
- Verify multi-origin transitions consolidated with the correct rule sets
- Grep your scripts for the removed transition-properties API; move to Bulk workflow APIs
- If you use approvals or order-sensitive rules, test those paths on a workflow copy
- Test every Marketplace-app workflow rule: opens, saves, shows a description
- Circulate the old-to-new rule name mapping to anyone who edits workflows
You don't need to migrate workflows themselves. Existing workflows carry over and stay editable. The risk isn't the workflows. It's the drafts, the scripts, and the assumptions.
If you hit something that doesn't behave the way it did in the old editor, drop it in the comments. I'm collecting edge cases from this rollout window and will keep this post updated through the 26th.
