Operation level costing (OLC)

Question

We are looking for a way to activate CU-OLC for existing open orders in a production environment. Our business challenge is that we have 8000 existing work orders in the production system not using CU-OLC. Once we promote our SPRO transport to activate the CU-OLC functionality, these existing work orders behave as per old standard SAP functionality (settlement rule only possible at the header level).
Here is some additional information on the question:
1. Our existing 8000 work orders are for order type TCOR
2. This order type has a settlement profile set to "not for settlement"
in our production system
3. There is no existing postings done to those orders (time, material,
other) are not allowed at this point
4. Once we push the transport to determine cost settings at the
activity level for this order type that only populates an entrey in
table T399X, along with another transport that will modify the
settlement profile to allow settlement, we expect existing orders to
behave as configured in table T399X.
Any idea how we can achieve this ?
