Easy ESXi 5.5 upgrade via command line

ESXi 5.5 was just released general availability (GA) on Sunday (9/22) and I’m itching to upgrade the home lab to run the latest version with all it’s goodies. I wanted to try upgrading my hosts without having to go through the same process that I followed setting up ESXi on the NUC in the first place, injecting custom NIC drivers, etc.

Enter the command line…

  1. Move all VM’s from the host and then put the host into Maintenance Mode.
  2. Go to the Configuration tab > Security Profile and Enable SSH under Services.
    ssh enabled
  3. Under Firewall, enable httpClient (outbound http).
    httpClient enable
  4. Open PuTTY (or other SSH client) and SSH into your host.
