We use a Cascading Select list custom field extensively across many of our projects. The parent option can be simplified to countries and the child options are clients located in that country. Under normal circumstances, I would never expect the clients to change countries. However given some re-organization and M&A's I've been asked to move clients to a different parent category.
Is there a way to do this within JIRA? (Follow up: Would that have to be done directly in the database?) I could disable the child option in one country and create a new on in the second, but this would break historical data about the clients and is less satisfactory than moving the client directly.
