I upgraded a 500+ VM environment to 7.0 U3c today and I would not say it went smoothly. After the upgrade, the appliance was running at 100% CPU for about 40 minutes before the vCenter Server service died and it became unmanageable. I opened a support case and, of course, it came up and acted fairly normal. Shortly after that call, the CPU shot up again. Has anyone else noticed this same behavior?
In addition to that, the install hung for about 45 minutes on "Converting data as part of post install". I have experienced that taking a while, but never 45 minutes. It did finally complete successfully. After that, I noticed the following message on the console screen: "vmdir.password is not set: aborting installation". That is a known issue and there is a KB article on how to fix it, but they could have fixed it in this release.
Since my case was opened as a sev-1, they didn't want to address the CPU utilization issue, just vCenter being down. They said I needed to open a separate case - which I find annoying since that is likely what is causing the poor performance and ultimately killing it. I have attached some images for reference.
