Data migration method and device, computer equipment and storage medium

The invention relates to a data migration method and device based on a cloud technology, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring migration information configured for original data migration, and splitting the migration information to generate a plurality of processing tasks which are allowed to be executed concurrently; acquiring the original data from an original database based on the migration information; performing fragmentation processing on the original data to obtain a data fragment corresponding to each processing task; calling a plurality of cluster applications corresponding to a target cluster in parallel, and concurrently executing each processing task through the plurality of cluster applications so as to convert the corresponding data fragments into storage data suitable for the target cluster; and migrating the storage data to the online service of the target cluster through the multiple called cluster applications
