Update ESXi 5.0 to 5.5 remotely

I needed to update a server from ESXi 5.0 to 5.5 which was hosted with OVH. I really didnt want to rebuild it using their installer as it would mean reformatting and rebuilding and also a lot of downtime. Luckily, it seems its possible to update it using esxicli. This is how i did it.

First, enable remote SSH if you havnt already. If it comes from OVH, it should do already.

Run the following commands to kick it off.

# open firewall for outgoing http requests:

esxcli network firewall ruleset set -e true -r httpClient


# Install the ESXi 5.5 U1 Imageprofile from the VMware Online depot

esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.5.0-20140302001-standard


# Reboot your host

reboot


It will look like it isnt realyl doing anything, but you can tail "/var/log/esxupdate.log"

You can check your ESXi version with "vmware -v"

 

Thats all.
