Upgrade the connection type

If you are accessing Google BigQuery using the Google BigQuery connection or the Google BigQuery ODBC connection, you can upgrade to the newer Google BigQuery V2 Connector. You can replace the source or target connection type in existing mappings and mapping tasks that use the Google BigQuery connection or the Google BigQuery ODBC connection with the Google BigQuery V2 connection.
After you replace the connection in an existing mapping, reimport the Google BigQuery object and remap the fields in the mapping. The configured advanced source, target, and lookup properties in the fields that are common between the two connectors are retained in the new connector. You can run the mapping successfully using the configured values from the old connector. You can additionally configure features that the enhanced Google BigQuery V2 Connector offers.
Note: If you are using the Google BigQuery ODBC connection or the Google BigQuery connection in mappings to read from or write data to Google BigQuery, Informatica recommends you to use the Google BigQuery V2 connection to make use of the features that the enhanced connector offers.
