Migration options

Migration options

When you migrate, you can choose from one of the following options to update the object path:

Option 1. Override the properties from the advanced properties

Before the migration, specify the required dataset and table name for the object from Org 2 in the advanced properties of the Org 1 mapping.
After the migration, when you run the mapping, the Secure Agent uses the configured advanced parameters to override the object specified in the mapping imported from Org 1.

Option 2. Parameterize the properties in the mapping

You can choose to parameterize the advanced attributes, such as the dataset and table name before the migration. You can configure input parameters, in-out parameters, and parameter files in the mapping. When you use a parameter file, you can save the parameter file on a local machine or in a cloud-hosted directory.
After you migrate the mapping, do not edit or update the mapping. If you have used in-out parameters, you can change the dataset and table attributes using the parameter file so that the changes are applied when the task runs.
Parameterizing only the advanced properties, but not the object in the mapping
If you want to parameterize only the advanced properties and use them at runtime, select a placeholder object in the object properties in the mapping and then specify an override to this placeholder object from the advanced properties. Ensure that the placeholder object contains the same metadata as the corresponding table that you specify as an override. When you run the mapping, the value specified in the advanced property overrides the placeholder object.
Parameterizing both the object and the advanced properties
If you want to keep both the Google BigQuery object type and the advanced fields parameterized, you must leave the
Allow parameter to be overridden at runtime
 option unselected in the input parameter window while adding the parameters, and then select the required object at the task level. When you run the task, the values specified in the advanced properties take precedence.
