Data migration method and device, electronic equipment and storage medium

The invention discloses a data migration method and device, electronic equipment and a storage medium. The specific implementation scheme is that the method comprises the steps: dividing a migration task of heterogeneous service data into at least two migration subtasks according to the classification of data obtained through preprocessing of the heterogeneous service data; carrying out data fragmentation processing on the at least two migration subtasks to obtain pre-migration first data described by data fragmentation; according to a mapping relationship between the first data before migration and the second data after migration, performing data conversion and data migration processing to obtain second data after migration; and verifying the first data before migration and the second data after migration, and updating the task state of the migration task after successful verification. By adopting the application, the data migration accuracy can be improved. 本申请公开了数据迁移方法、装置、电子设备及存储介质，具体实现方案为：将异构业务数据的迁移任务，根据针
