1. A method for data migration, comprising:
obtaining feature data of a plurality of logical storage units in a first storage device, the feature data comprising deduplication information of each of the plurality of logical storage units;
determining, based on the feature data, a set of similarity values between the plurality of logical storage units;
migrating a logical storage unit having a similarity value higher than a similarity threshold among the plurality of logical storage units from the first storage device to a second storage device different from the first storage device;
performing deduplication operations on data blocks in the plurality of logical storage units;
counting the deduplication operations on at least some of the data blocks; and
determining data blocks for which the number of deduplication operations is greater than a threshold number as deduplicated data blocks.
