Update wf_notifications.recipient_role after fnd_user.user_name change? Is there a way to avoid doi

We are about to update all fnd_user usernames.

The table wf_notifications stores the user_name and unless they are updated to the new value, the WF will error.

Is there a way to do this other than:

1 Rewinding the workflow

2 Withdrawing the transaction (if OIE) and resubmitting.

3 Manually updating the WF attributes for each open WF

Does "Synchronize WF LOCAL tables" do this?

Appreciate some practical advice.
