What solution are you looking towards? I work in a massive organization with 20,000+ VMs and we’ve been having weekly virtual working groups across the country (our overseas depts have been doing their own) to try and discuss finding other solutions. We haven’t been very successful, as the biggest pitfall we’ve seen is no one offers lifetime licenses so if we don’t renew a yearly maintenance our VMs won’t stop functioning properly. That’s one of the main reasons we’re looking to off board from VMware.
