As per the documentation of CUCM 10.x, it does not support the MCS machines anymore, only virtualized. How could this be practicle and logical? What about those who have bought Cisco MCS I5 machines with 3 yrs UCSS just last year and now you telling us that its not gonna take version 10.x on it? Many people would have made sizable investment on such setups... Is that all obsolete now?
This does not sound justified to me. There has to be some way out.
