Thanks for the instructions on restarting the upgrade process. My hypervisor upgrade got stuck when one VM failed to migrate. Once I resolved that issue the upgrade didn’t resume on its own. But after running the four commands you listed, I was able to start it back up from Prism. Saved me a call to tech support.
