Challenges with the migration to the topic-per-event topology

I can’t upgrade yet because
NServiceBus.AzureFunctions.Worker.ServiceBus doesn’t support it yet.

Will this also be upgraded?

Other question:
It’s not clear to me from the manual. if we need todo this manual or if the installer takes care of this. I assume the later?
topology.SubscribeTo<IOrderStatusChanged>("Shipping.OrderAccepted");
