Abstract: Techniques for data migration involve obtaining, at an edge device, a bitmap in a local memory, the bitmap including a plurality of parameter values. The techniques further involve updating, in response to a data block being written or read, a data heat value of the data block based on the bitmap. The techniques further involve migrating the data block between the edge device and a cloud device based on the updated data heat value. Accordingly, there is a solution for migrating data blocks between an edge device and a cloud device, such that data with a high data heat value is stored at the edge device and data with a low data heat value is stored at the cloud device, thereby improving the performance of a storage system.
