Use a different object path for the migrated mapping

After you migrate the mapping, you can use a different object path to run the mapping from the new environment.
In this scenario, before you migrate the mapping, you can change the object metadata, runtime attributes, or the connection attributes to reflect the object path in the migrated environment. You do not have to edit or update the mapping in the new environment.
As a rule, when you specify the folder path and file name in the advanced properties, connection, or object properties, Data Integration honors the attributes in the following order of precedence:
  1. 1. Runtime advanced attributes. The advanced properties such as the folder path and file name in the Source, Target, or Lookup transformation in a mapping.
  2. 2. Connection attributes. The folder path attribute in the connection properties.
  3. 3. Object metadata. The object selected in the Source, Target, or Lookup transformation in a mapping.

Migration options

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

Option 1. Update the connection properties to reference the new object

When you import the mapping into Org 2, in the Review Connections section, you can change the existing connection to map to the connection that has access to the specified folder path and file name in Org 2.

Option 2. Override the properties from the advanced properties

Before the migration, specify the required folder path and file 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 3. Parameterize the properties in the mapping

You can choose to parameterize the advanced attributes, such as the folder path and file name before the migration. You can configure input parameters, in-out parameters, and parameter files in the mapping. After you migrate the mapping, do not edit or update the mapping. If you have used in-out parameters for the advanced attributes such as for the folder path and file name, you can update these from the parameter file.
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 Amazon S3 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.

Parameterization rules

Consider the following rules to parameterize the object and advanced properties:
