Google Cloud Storage V2 Connector > Upgrading to Google Cloud Storage V2 Connector > Connection switching example

Connection switching example

You want to upgrade your existing Google Cloud Storage V1 mapping that uses the Google Cloud Storage connection to the Google Cloud Storage V2 connection.

1Open the existing Google Cloud Storage V1 mapping that you want to upgrade to Google Cloud Storage V2.

The following image shows an existing mapping that uses the Google Cloud Storage connection and contains the configured advanced properties in the Target transformation:

The connection type used is Google Cloud Storage V1 connection.

The configured target object path in this example is: gs://bucket1/___________.csv

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 Google Cloud Storage V1 mapping:

- To retain the fields automatically mapped after the switch, select Automatic.

On the Field Mapping tab, the field mapping option is selected as 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 the retained fields using the previous mapping.

3To switch the connection, in the Connection field, change the connection from Google Cloud Storage V1 to Google Cloud Storage V2.

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 Google Cloud Storage V1.

The following image shows the options that you must select:

The dialog box shows the options to retain the advanced properties and the field mapping.

5Use the same object path in the mapping as Google Cloud Storage V1.

The following image shows the switched connection with the same object path: gs://bucket1/___________.csv

The connection is switched to Google Cloud Storage V2 type.

The configured target advanced properties from the Google Cloud Storage V1 mapping reflect in the Target transformation.

6If you had selected Manual on the Field Mapping tab in the Google Cloud Storage V1 mapping and you want to reflect the field mappings in Google Cloud Storage V2, on the Field Mapping tab, select Automap, and then select Previous Mapping.

The automap option is selected to retain the mappings from the old connector.

Note: If you had selected Automatic in Google Cloud Storage V1, you do not have to perform this task.

In the following image, the configured mapped fields from the Google Cloud Storage V1 mapping reflects in the Google Cloud Storage V2 mapping:

The Field Mapping tab shows the mapped fields reflecting in the Google Cloud Storage V2 mapping.
