Abstract:
A method for migrating volumes of data supporting a source data center, comprising a source mainframe and a source DASD, to a target data center, comprising a target mainframe and a target DASD, to support the migration of one or more applications from the source mainframe to the target mainframe, comprising the steps of:(a) verifying data integrity on the source DASD; (b) initiating one or more processes to mirror the volumes of data from the source DASD to the target DASD, and to mirror one or more data updates to the volumes of data by the applications of the source mainframe to the target DASD; (c) synchronizing said data updates to the volumes of data by the applications of the source mainframe with corresponding data updates to the target DASD; (d) deactivating the applications of the source mainframe; (e) mirroring one or more remaining data updates to the volumes of data by the applications of the source mainframe to the target DASD; (f) disconnecting the source data center from the target data center; and (g) bringing the target data center on-line and initiating the applications of the target mainframe.
