The embodiment of the invention discloses a data migration method. The data migration method comprises the following steps: receiving the storage path configuration information sent by a target migration terminal after the target migration terminal is accessed, wherein the storage path configuration information includes a corresponding relation between data types and storage paths; receiving a data migration instruction, obtaining a target file corresponding to the data migration instruction, and confirming a target data type corresponding to the target file; confirming a target storage path corresponding to the target data type according to the corresponding relation between data types and storage paths; and sending the target file to a storage address corresponding to the target storage path of the target migration terminal. In addition, the embodiment of the invention also discloses a data migration device. By means of the embodiment of the invention, the setting flexibility of the storage path of the migration data can be improved.
