A method, article of manufacture, and apparatus for processing information are disclosed. In some embodiments, this includes mapping a target multi-controller system, determining a target controller to send a data chunk to based on the mapping, determining if the target controller is missing any portion of the data chunk, and sending the missing portions of the data chunk to the target controller. In some embodiments, sending the missing portions of the data chunk to the target controller includes sending the missing portions of the data chunk from a source multi-controller system to the target. The source multi-controller system may have a first number of controllers and the target multi-controller system may have a second number of controllers.
