Full Data Migration | Migrate data by sequentially scanning data in tables and writing it in batches to the target database. |
Incremental Data Sync | Sync of common DML like INSERT, UPDATE, DELETE is supported. |
Data Verification and Correction | Verify all existing data. Optionally, you can correct the inconsistent data based on verification results. Scheduled DataTasks are supported. |
