I have 6 Unity arrays, and set them up with certificates from my internal CA to make browsers happy. These arrays have since been configured to communicate with a Unisphere Central appliance. Now, the certificates have expired. When I issue the command from the Unity shell to update the new certs I have staged, the command fails with a message that it failed because the array is connected to Unisphere Central. Ok, fine. I disconnect from UC, and the cert update command processes fine. I connect back to the UC ... and discover that all my historic capacity and performance data is gone. 

Is there a way to update certs without disconnecting from UC ?
