Oracle Fusion Learning migration from instance to instance

Hello everyone,I want to migrate the Learning Setup from Test to PROD.Is there a documentation on how to do it?I've found this How to migrate Learning Contents from Test Instance to Prod Instance — Cloud Customer Connect, it links a document that describes loading Course (Loaded in via HDL) , Offering (Loaded in via HDL) , Self-Paced Activity (Loaded in via HDL) , Rich Media Content Item (Loaded in via REST)

But there is more to learning.For some of them seem possible in an Implementation Project.Please let me know if you know how any of these can be loaded, or if you know that one has be migrated by hand.
