You can reassign the deployed source, rules, and responders from one source controller, event processor, and responder controller to another source controller, event processor, and responder controller.
For example, if you have deployed a responder in one responder controller, but you want to switch the responder to another responder controller, you can use the reassign option. You can also reassign the responder from standalone mode to high-availability mode. If you have enabled the responder controller for high availability, the grid manager reassigns the sources to all the configured backup controller instances.
You can reassign mapped objects only when the objects are in Deployed or Needs_Deployment state. On successful completion of reassign, the state of the objects changes to Deployed.
