Points of My Scenario: 1. I have successfully deployed Unity VSA using the OVA download from Dell EMC UnityVSA Download | Dell EMC . 2. I have successfully run and licensed the Unity VSA, BUT... 3. I cannot register VASA Provider in VMware due to an expired certificate (2015) 4. I read that there is a version of the UnityVSA ova file that has a legitimate certificate.  REQUEST: Please direct me on how to acquire the UnityVSA ova version with a certificate that is not expired.
