hi, i have an inquiry about the following case:
O- a customer have a CUCM v.11.5 out of support ,also he will get a new CUCM v.14
O- so we will let him get the flex plan licenses only ( not a CUCM server)
O- is it must to offer the vmware licenses (Vsphere & Vcenter licenses) , or he may use the preloaded hypervisor licenses on the old CUCM to use it with the new flex licenses ?
