Planning to upgrade my environment with latest vmtools version 10.2.5 or 10.2.0 with VM hardware version 11 on ESXi OS version 6.0. Which one to be installed / upgraded first - vmtools or vm hardware?

My question is - first install vmtools version, reboot the server and install / upgrade vm hardware version? or install / upgrade the vm hardware version first, reboot the server and install vm tools version? do I need to follow any specific order here. If yes, what is the reason behind??

Thanks in advance.
