After the upgrade of vCenter yesterday, the goal for today was to upgrade 2 hosts to ESXi 4.1. The old hosts are running VMware ESX 4.0, since vSphere 4.1 is the last release containing VMware ESX I decided to make the move to ESXi to be prepared for future releases.
Because I was running ESX I had to perform new installations on the metal. The initial installation of ESXi 4.1 is pretty strait forward, just download the installable iso, burn it to a CD-ROM, put it into the server, boot from the CD, answer some questions and you’re ready to go.
I was surprised that all my old ESX 4.0 configuration scripts (PowerCLI) after some minor changes worked on the new ESXi host.
Bottom line, 2 hosts down, 6 to go.
