CCM 4.1, 42,4.3

I am still recommending my new customers to purchase Call Manager 4.1(3) if they are not sure whether to move towards Linux Based Call Manager or not in the future. If a client doesn't want Linux based Call Manager down the road then would it be a good idea to go with either Call Manager 4.2 or 4.3?


I heard that only up to CCM 4.1(3) allows the easy migration path toward Linux Based CCM such as 5.1/6.0.


Thanks,

Hi Abbas,


From 4.2 there is a direct upgrade path to 6.x which is very good, but not to 5.x as you have noted;
