Upgrading from ESXi 6.5 to ESXi 6.7 via SSH and esxcliFollowing
VMwares release of ESXi 6.7, I upgraded my ESXi 6.5 server to ESXi 6.7 using SSH and
esxcli. For those interested, see below the jump for the details of the process I used.
To upgrade from ESXi 6.5 to 6.7 using esxcli 1. Shut down all VMs running on your ESXi host machine.
2.
Enable SSH on your ESXi server, if it is not already enabled.
3. Connect via SSH.

4. Once logged in, run the following command to enter
maintenance mode:
1 | vim-cmd /hostsvc/maintenance_mode_enter |
5. After putting ESXi into maintenance mode, run the following command to set the correct firewall rules for the httpClient:
1 | esxcli network firewall ruleset set -e true -r httpClient |
6. Next, run the following command to list the ESXi 6.7 updates available. You want the latest one that ends in
-standard for your version of VMware.
7. Once youve identified the correct version of VMware (as of 5-18-2018, this is
ESXi-6.7.0-8169922-standard), run the following command to download and install the update.
Note: It is very important that you run esxcli software profile update here. Running esxcli software profile install may overwrite drivers that your ESXi host needs. 8. Once the update has been installed and prompts you to reboot, run the following command to restart:

9. After your ESXi host restarts, connect via SSH and run the following command to exit maintenance mode:
1 | vim-cmd /hostsvc/maintenance_mode_exit |
At this point, your ESXi host should be upgraded to ESXi 6.7.0.
