Updating old esx servers to ESXi 6.7

A few of the old ESXi servers are lying around and needs to be upgraded.

Power all VM.
Turn on maintenance mode.
Enable SSH
SSH into the server

esxcli network firewall ruleset set -e false -r httpClient
esxcli software sources profile list --depot=https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml | grep 6.7
esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-6.7.0-8169922-standard
Might wanna open another SSH
tail -f /var/log/esxupdate.log
esxcli network firewall ruleset set -e false -r httpClient
reboot

6.7.0 (Build 8169922) -> :)
