Easy ESXi 6.0 upgrade via command line

VMware has released ESXi 6.0 (what’s new in 6.0) back in March and I recently posted a guide on how to upgrade your vCenter Server Appliance from 5.x to 6.0 – Now we’re going to look at two ways to upgrade a VMware ESXi 5.x host to ESXi 6.0 via command line.

The first method will show you how to have each ESXi host download the update directly from VMware and then upgrade itself while the second method shows how to download the update, place it on a datastore accessible to the host, then upgrade the host.

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.
