As the server was not originally setup to run Cacti it does not have a desirable amount of CPU and RAM. Since it is a VM the process to upgrade the hardware is barely more time than a shutdown and boot up will take.

I am going to do this shortly so the server/site will be offline for a few minutes and there'll be a small gap in the data possibly. I will try and time it to be in between polling intervals so it may not even miss any data.
