Data Management on Target Environment
Delivery Channels : Message Scenarios and Outbound Integration
The delivery channels end points are preserved on the target environment at the beginning of refresh environment operation and restored upon completion of the operation. The application restores the end points only for delivery channels for which the source and target environments match (for example, same delivery channels on Production and Test).
The delivery channels that don't match and end points are deleted, so you must configure them again.
Applications
You'll need to regenerate the Client ID and Client Secrets in the copy and configure the end points manually to enable communications.
Data Deletion
After the operation is completed, all the data present on the target environment is deleted permanently without the possibility to restore it.
