Hi there! Welcome to my blog. My name is Ivan. I am a Dutch IT Professional working as Principal IT Consultant. I am running several VMWare ESXi4 servers and I wanted to upgrade them to the latest release of ESXi4.1. The following steps I used to achieve this job in less than 5 minutes. Please make sure you installed vSpere CLI and download the upgrade package on you system before you can start.

I’ve done it a few weeks ago, with any worries at all.
There’s a similar script for 3.5, for installing it’s patches/updating. The process is pretty much the same.

Thanks Alex for being here. I learned about these scripts not long ago and before that I used the Update utility. For some reason it failed to update my ESXi servers to 4.1 and therefore I learned about these steps.
I like this much more than having the GUI 😉
