Hello,
I was trying to upgrade SAP Commerce from version 1811 to 1905. Our B2B accelerator is based on subscription. But I have noticed most of the subscription based classes or bundle related logics are removed from Order/Cart. We are using for instance DefaultSubscriptionCartFacade class. How do we proceed for these changes? Any specific guidelines if we are dependent of `subcriptionfacades/subscriptionservices` core classes? What are the guidelines of migration if we are dependent on subscriptionbundles or subcriptionfacades/subscriptionservices.
