ESX is dead, long live ESXi!

VMware vSphere 4.1 is going to be the last release of ESX; there will be no ESX 4.2. From now on it will be ESXi all the way.

From: http://www.vmware.com/support/vsphere4/doc/vsp_esxi41_vc41_rel_notes.html

1) VMware ESX. VMware vSphere 4.1 and its subsequent update and patch releases are the last releases to include both ESX and ESXi hypervisor architectures. Future major releases of VMware vSphere will include only the VMware ESXi architecture.

2) VMware recommends that customers start transitioning to the ESXi architecture when deploying VMware vSphere 4.1.

“What I don't get is how they link you to the VMware ESX to ESXi Upgrade Center and there is nothing there. Also, don' take this as a real "upgrade" per se, it's more of a side-grade. Digging a bit further and we get to the Upgrade from ESX to ESXi page which shows no real process of "upgrading". So from what I see, the only upgrade is to wipe and fresh install.”
