Abstract
A system and method for changing between various levels and configurations of redundant array of independent disk (RAID) implementations is provided. A specialized driver establishes a specialized “morph” container in a top level above primary and secondary level containers. The morph container communicates with the host computer I/O and arranges mapping of data between an original source container configuration and a new destination configuration. A morph container mapping structure is implemented to accomplish the mapping therebetween. Where data is migrated from an original container space back into an original space, a temporary container can be established to facilitate the transfer between the space.
