The present disclosure discloses a data migration method and a system based on a storage cluster, and a storage medium. The method includes: triggering a dual write mode of a block storage access client in response to a data migration instruction, and implementing incremental data synchronization to a source storage cluster and a target storage cluster by executing the dual write mode, where the data migration instruction is used to instruct to migrate data in the source storage cluster to the target storage cluster; and triggering a storage node in the source storage cluster to generate corresponding snapshot data for existing data in response to the data migration instruction, and migrate the snapshot data to the target storage cluster.
