A method and system for migrating computer applications and volumes of data from a source DASD connected to a source computer system to a target DASD connected to a target computer system. The method comprises ensuring data integrity on the source DASD, initiating one or more processes to mirror all data and all data updates from the source DASD to the target DASD, ensuring synchronization of data updates to the source DASD by the source computer system with data updates to the target DASD, deactivating all applications executing on the source computer system, mirroring one or more remaining data updates to the source DASD by the source computer system to the target DASD, disconnecting the source computer system and the source DASD from the target computer system and the target DASD; and bringing the target computer system and the applications executing on the target computer system on-line.
