I found the solution.  Seems like you cannot upgrade directly from 2.0.0 to 2.1.2.  I first upgraded to 2.1.0 that allowed me to upload a file of gpg extension.
Trying to install the latest VNXe Operating Environment 2.1.2 MR1 SP2.  It downloads with a .gpg file extention that I assume is encrypted. Cannot find any instruction to decrypt it.  Does anyone know howto?
