Abstract
The invention transforms source data from a source platform to a target platform with a single copy. A data request signal is communicated from the target platform to the source platform and a location of the source data is determined in a disk subsystem supporting snapshot. The disk subsystem (i.e., a snapshot facility) copies the source data in raw form to one or more target disks designated by the target platform. The locations of the source data and the target disks are communicated to the target platform and the source data is read from the disk subsystem to transform the data to the target platform. The process starts from a request of an application resident within the target platform. One or more data management units can be used to determine source and target disk locations. Preferably, the source platform also communicates metadata to the target platform; and thus metadata, when available, is also copied via snapshot operations in the disk subsystem. The use of Snapshot creates a static copy to help ensure data integrity.
