When using the REST API to update a ticket (XML-RPC), we have a use case where the ticket may have moved to a different project, but the client still knows it having the first key. ie, the issue was created having key AD-13362 but was then move to ED-236. In the actual Jira interface you could search for AD-13362 and ED-236 would come up, however this does not work with the API.
My question is, has anyone had a use case like this? And is there a workaround to have the API know that AD-13362 is now ED-236?
