You want to upgrade your existing mapping that uses the Microsoft Azure SQL Data Warehouse V2 connection to use the Microsoft Azure Synapse SQL connection.
Before you switch the connection, perform the following steps:
1Open the existing Microsoft Azure SQL Data Warehouse V2 mapping that you want to upgrade to Microsoft Azure Synapse SQL.
The following image shows an existing mapping that uses the Microsoft Azure SQL Data Warehouse V2 connection and contains the configured advanced properties in the Target transformation:
The configured target object in this example is: emp_conn_tgt.
2To retain the mapped fields from the field mapping when you switch the connection, on the Field Mapping tab, choose from the following Field map options menu in the Microsoft Azure SQL Data Warehouse V2 mapping:
- To retain the fields automatically mapped after the switch, select Automatic.
- To manually map the retained fields after the switch, select Manual.
Note: When you select manual, after switching the connection, you have the option to automap using the previous mapping.
3To switch the connection, in the Connection field, change the connection from Microsoft Azure SQL Data Warehouse V2 to Microsoft Azure Synapse SQL.
4In the Change Connection dialog box, select the following properties, and click Yes:
- Connection switch. Switches to the connection that you select.
- Retain field mapping. Retains the configured field mappings from Microsoft Azure SQL Data Warehouse V2.
The following image shows the options that you must select:
5The object from Microsoft Azure SQL Data Warehouse V2 is retained.
The following image shows the switched connection with the same object:
The configured target advanced properties from the Microsoft Azure SQL Data Warehouse V2 mapping reflect in the Target transformation.
6If you had selected Manual on the Field Mapping tab in the Microsoft Azure SQL Data Warehouse V2 mapping and you want to reflect the field mappings in Microsoft Azure Synapse SQL, on the Field Mapping tab, select Automap, and then select Previous Mapping.
Note: If you had selected Automatic in Microsoft Azure SQL Data Warehouse V2, you do not have to perform this task.
7Click Save.
In the following image, the configured mapped fields from the Microsoft Azure SQL Data Warehouse V2 mapping now reflects in the Microsoft Azure Synapse SQL mapping:
