Would like to see the product support moving from a 2012 hierarchy which is using custom ports for client communication and IIS bindings, into a CB hierarchy that is using default ports. My understanding is that both environments need to match exactly from a port perspective and we have over 400 remote DP's that will need to be removed manually from SCCM 2012, reimaged and then redeployed as remote DP in CB all over slow links. We have no internet connectivity options for a cloud DP scenario in these location (like China). This will significantly delay our migration globally to CB. Please consider providing support for multi-port migration scenarios.
