Hi Gue, David,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
Warning is attached to the dataset’s connector type, not just the linked service.
If the dataset was created from the older Jira connector (or cloned from one), it will keep the “older version will be deprecated soon” banner even after you point it to a new linked service.
What usually fixes it:
- Create a brand-new dataset from the new Jira connector card (don’t clone the old one).
- Pick the upgraded linked service and re-select the table/JQL options so the dataset JSON is generated with the new connector schema (OAuth2 props, new type name/fields).
- Re-point every activity that used the old dataset to this new dataset. In ADF, use View all references or search the repo for the old dataset/linked-service name to catch any inlined sources in Copy/Data Flows.
- Publish the changes, then open Live mode (or refresh the browser) to confirm the banner is gone.
- Remove the old dataset and (if still around) the old linked service.
After those steps the dataset warning should disappear. If it doesn’t, there’s likely still an old dataset/inlined source in the pipeline referencing the deprecated connector.
