Hi !
As the Web Interface isn't available without a vcenter, i've created a VM with a V8 hardware (the highest available through the VSphere client) where i've installed the VCenter server. Now i wonder how to upgrade the HW to v9 ... If i shutdown the Vcenter, the web interface isn't available anymore and it's required to upgrade to v9. 
There is an option "Schedule VM Compatibility Upgrade" in the Web Interface you can select to do the upgrade at next reboot but does he need the Vcenter server to be available ? Would it work on the vcenter server ?
Any clue on how to solve this ?
Regards
