Good day.
We are currently running the free version of VMware ESXi 5.0. We wish to move to ESXi210 5.5 so we can install a second CPU and more memory. At the same time we would like to install the Essentials Kit. I am a bit confused as to the order in which we should proceed. 
My plan so far is:
1. Upgrade to Free ESXi 5.5
2. Shut down and install the CPU and RAM.
3. Power up and install the Essentials Kit. (I understand that this is done by entering the Essentials Kit key.)
Does this sound reasonable? Is there a better way of proceeding?
Also, if we were to install the Essentials Kit first, does the host need to be restarted for the change to take effect?
Thank you for your time,
David Chapman
