VMWare VM Hardware Version 10 Warning!

Just a quick shoutout to tell any of my readers to avoid upgrading critical infrastructural VMs to Hardware Version 10.

You cannot use the vSphere Client to edit the settings of virtual machines of version 10 or higher.
Use the vSphere Web Client to edit the settings of this virtual machine.

In the event the web-client isn’t functional you won’t have the fat client in Windows to help rescue the day. Personally I’m avoiding the upgrade of my vCenter server and one of my Domain Controllers. I’ve had issues in the past whereby the dvSwitch has been corrupted for some reason and I had to fall back on a standard switch to regain network connectivity for VMs. Now if you have such an issue then once you’ve upgraded to HW 10 your only option will be to edit the vmx file directly.

Best to reserve the use of the HW 10 for consumer VMs and non-critical infrastructure until VMWare issue an advisory to cope with this type of issue.
