摘要

Embodiments for using a migration data placement tool between storage systems based on data access by a processor. Events from a plurality of heterogeneous storage systems may be indexed into a common repository. A migration data placement tool uses analytics to determine data placement of the data in a target storage system according to the data identified as hot data, warm data, or cold data based on the events indexed in the common repository. The data may be placed according to a migration template during migration to the target storage system.
