description Embodiments of the invention provide a data migration method and device. The method comprises the following steps of: obtaining state information of multiple storage devices; determining an emigrationdevice of to-be-emigrated data and immigration device of to-be-immigrated data from the multiple storage devices according to the state information; selecting to-be-emigrated target data from the data stored in the emigration device; and migrating the target data to the immigration device from the emigration device. On one hand, state indexes such as IOPS, throughput bandwidth and the like can besynthesized to comprehensively assess performance of the storage devices, and equipment storage files are selected from the storage devices, so that demands of different businesses are satisfied, file storage under multiple businesses is realized and the resource waste is decreased, and on the other hand, states of different storage devices can be synthesized to carry out data migration, so thatload balance between the st
