VMware: Upgrade ESXi 4.0 to 4.1
I run several VMware ESXi 4.0 servers and wanted to upgrade them to ESXi 4.1. The following steps took me less than five minutes. Install the vSphere CLI and download the upgrade package before starting.
Upgrade to ESXi 4.1
- Install vSphere Command-Line Interface
http://www.vmware.com/support/developer/vcli/ - Download the ESXi 4.1 (upgrade ZIP from ESXi 4.0) upgrade package
https://www.vmware.com/tryvmware/p/activate.php?p=free-esxi&lp=1 - Store the ZIP on a local drive, such as c:\vmware. Start the vSphere CLI and run the following command:
Code1 line 1perl vihostupdate.pl --server 192.168.200.1 --username root --password password --install --bundle c:\vmware\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip - Restart the ESXi server and verify that the upgrade to ESXi 4.1 completed as expected.
Upgrade demonstration
In this demo, I will upgrade my VMware ESXi 4.0 server to ESXi 4.1 using the vSphere CLI tools. The server should be up and running in less than five minutes.

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 ;-)
Hi. I get the following error when I do this:
Error: Server version unavailable at 'https://localhost/sdk/vimService.wsdl'
Please help
Hi Mike,
I have not experienced this problem myself before. Please try this post here: http://www.omniweb.com/wordpress/?p=545
