I will be install ESXi 5.1 in our lab butt using the free hypervisor version. We already OEM CD's we use from IBM. Could I use one of these CD's on a IBM server in our lab then apply the hypervisor license? From my understanding the binaries are the same it is the license key when opens up the features or not.
Also will the hypervisor 6 key work on 5.1? I need to get 4 separate keys to cover our four test servers but can only register on email account at at time
