How Do I Import GaussDB(DWS)/Oracle/MySQL/SQL Server Data to GaussDB(DWS) (Whole Database Migration)?

Heterogeneous data can be imported to GaussDB(DWS) using CDM. You can migrate an entire Oracle, MySQL, SQL Server, or GaussDB(DWS) database to a GaussDB(DWS) databse. For details, see section "Creating an Entire Database Migration Job" in the Cloud Data Migration User Guide.

You can also store data to OBS and then dump the data to GaussDB(DWS). For details, see section "About Parallel Data Import from OBS" in the Data Warehouse Service (DWS) Developer Guide.
