Upgrade ESXi 5.5 to 6.0 via ssh

I recently updated an ESXi 5.5 host to 6. This is a remote machine so didnt have access to load the ISO. This is how i did it via SSH and ESXCLI.


Running through the ESXi update:

# Shut down all running VM's

# Put ESXi host into maintenance mode

~ # vim-cmd /hostsvc/maintenance_mode_enter

# Allow httpClient access out through the firewall.

~ # esxcli network firewall ruleset set -e true -r httpClient

# Run the following command to download and install the update. Make sure you use "update" here DO NOT use "install" as it may overwrite drivers that you need.

~ #  esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-6.0.0-20150404001-standard

# Once that is complete, go ahead and reboot the host

# After your host has rebooted, take it out of Maintenance mode

~ # vim-cmd /hostsvc/maintenance_mode_exit

# That should be it.
