Custom and Inbound WSDLs Unavailable after Migration

When an integration that includes a Salesforce endpoint as a trigger or invoke (configured with a custom application built using Apex classes and hosted on force.com) operation is exported and imported into another Oracle Integration environment (for example, from test to production) and the Salesforce connection already exists with the same name, the connection does not save the WSDL files as a part. Therefore, when you edit the Salesforce endpoint, you do not see the uploaded custom or outbound messaging WSDL files and you must upload these files again in the Adapter Endpoint Configuration Wizard.
