Upgrade vSphere 4.0U2 ESXi to 4.1 ESXi

How to upgrade your ESXi 4.0U2 to ESXi 4.1. Contrary to what some may believe. VMware's documentation is not the simplest to navigate sometimes. However, this is what happens when you have technical writers typing up stuff for Systems Engineers! We don't need 10 pages of text to say the following!

You need vSphere CLI - Download Here vCLI
For Windows or Linux and install on your workstation.
Download the Upgrade Package for 4.0 to 4.1 or the Upgrade Package from 3.5 to 4.1
Power off your VM's and put the host into maintenance mode from the vSphere CLI prompt: --server hostname or IP -i -b c:\temp\ -B ESXi410-GA --server hostname or IP -i -b c:\temp\ -B ESXi410-GA-esxupdate
