No, we're not. Our environment is small; only about 100 VMs. We're a Debian shop, so no redhat.

No, it's not a 1:1 replacement. It's a migration. It would also be a migration if we decided to upgrade OpenStack, because we'd be going Havana -> Ocata.

However, there are defined upgrade paths for ESX, we already have ESXi/vSphere in our environment, and we can hire someone relatively inexpensively to help us with vSphere if we need to augment our staff. Folks who understand Openstack are not anywhere near as easy to find and pay.
