This technical paper discusses incompatibilities between the ESX 3.5 service
console and the ESX 4.0 service console. Included are suggestions of what you might do to upgrade your
existing environments that depend on the ESX service console. This document also discusses how you might
bridge the gap to support ESXi, which does not include a service console. And finally, if you are currently
writing applications that run in the ESX service console, this document suggests some possible options you
have for transitioning away from it.
