Correct Keith. It has to be removed from the cluster.  Thanks,    Zahid Twitter: [NAME]
Hello,  There isn't any information on the impact/requirements around RP4VM's when virtual center is upgraded and I just performed it in our lab and the result was RP4VMs blowing up and going into regulation mode. I have opened a case, but was curious if anyone has performed this before and what their results were?  Thanks.  -Keith
