Upgrade/Update ESXi 6.5 to 6.7 Offline

  1 minute read

In our Homelabs, we normally make some “architecture compromises” that add some extra complexity when we need to upgrade it.

And in my particular case, was starting with a “single host” with enough resources to run a couple of Nested Environments, there are plans  to add one or two more hosts, but for now has been enough for the current use.

Running everything from a single host creates some challenges when is time for BIOS/Firmware updates and ESXi upgrade/update.

Let’s go through the process to upgrade an ESXi hypervisor offline

remember your mileage may vary in some of the parts, but the process should work for more than ESXi 6.5 to ESXi 6.7 upgrade

  1. Download the offline bundle and upload to a local datastore

  2. Will not describing the download process and upload, since there are different ways to achieve this

ESXi Upgrade - Offline patch

  1. Shutdown all your VMs

  2. Do a dry run just to make sure

esxcli software profile update
   -d /vmfs/volumes/<local>/VMware-ESXi-6.7.0-8169922-depot.zip
   -p ESXi-6.7.0-8169922-standard --dry-run

ESXi Upgrade - dryrun

  1. This dry-run will give us a list of what will be applied and installed

  2. Enter Maintenance Mode

esxcli system maintenanceMode get
esxcli system maintenanceMode set --enable=true
esxcli system maintenanceMode get

ESXi Upgrade - Enter Maintenance Mode

  1. And we are ready for the upgrade

    1. Lets kick off the upgrade
esxcli software profile update
  -d /vmfs/volumes/<local>/VMware-ESXi-6.7.0-8169922-depot.zip
  -p ESXi-6.7.0-8169922-standard --dry-run

ESXi Upgrade - Start

  1. The command is not too verbose, but we can open a 2nd SSH session and tail the esxupdate.log file

ESXi Upgrade tail esxupdate

  1. Will give you a quick report, similar to the dry-run, but now with the actual changes

ESXi Upgrade - Finished

  1. Reboot

    • Now, we need to reboot the host to get the upgrade finished

    ESXi Upgrade - Reboot

  1. Take out of Maintenance Mode

    • Let’s remove it from Maintenance Mode

ESXi Upgrade - ESXi FirstBoot

esxcli system maintenanceMode get
esxcli system maintenanceMode set --enable=false
esxcli system maintenanceMode get

ESXi Upgrade - Exit Maintenance Mode

  1. All done and a final picture with our Upgraded/Updated ESXi
