Claim:
1. A method, in a data processing system, for importing pre-existing data into a first storage system of the data processing system utilizing a current storage management system that is different from an original storage management system used to create the pre-existing data, the method comprising: integrating one or more data storage devices into the first storage system in-place without modification of the pre-existing data stored on the one or more data storage devices; creating metadata for the pre-existing data based on a linear progression of data in the pre-existing data, wherein the metadata specifies location information for locating portions of data in the pre-existing data of the one or more data storage devices based on an assumption of a linear progression of data in the pre-existing data; executing read access requests targeting the pre-existing data using the created metadata; and executing write access requests targeting the pre-existing data by redirecting the write access requests to a copy of the pre-existing data created in another storage location, wherein the metadata that is created has a configuration, corresponding to the current storage management system used to manage storage devices of the first storage system, that is a different configuration from metadata used by the original storage management system when creating the pre-existing data in a second storage system different from the first storage system.
