Do I risk any VM performance issues during vCenter VCSA upgrade from v6.5 to v6.7 on vSAN cluster? From my experience the only caveat of performing a vCenter upgrade is not being able to access the vCenter GUI for a limited time, but VM's should continue to function during vCenter upgrade. Just want to confirm this with the community. If there is a high risk of affecting any CPU/MEM/Network/IO VM performance, I will opt to perform the upgrade during off-peak hours.
Feedback appreciated.
