Can you tell me what old MCU you have and what you are looking to do. You may or may not need to migrate to a new MCU. The latest appliance MCU is the 5300 series or we have an MSE8000 chassis based system that has 8510 MCU cards.
today they had MCU model and we also ongoing to proposing new Telepresence infra (TMS/VCS-C/VCS-E) and MCU 5300 series to cascade with their exiting UC environment. (as attach slide state that "Optimize TelePresence" working only MSE8XXX/TP7XXX/MCU5300 and UCM at least 8.6.2 or later). seem like customer need to replace existing MCU 4200.
and 2nd question.
the question was came up after customer seen new feature that we can adding ad-hoc/meet me MCU as media resourse. but today they several had 10 callmanager server each location , so if need to add media resource to every UCM will not make sense.
as we seen new Cisco solution to optimize video resource by adding component like conduct to manage many MCU and control MCU resouce. is it possible for conductor to manage 1 MCU for 10 UCM ad-hoc resource. once have more customer demand they can add-on 2nd or 3rd MCU?
