Upgrading a ESXi 6.5 to 6.7 Update 1 on a HP Microserver Gen8 & older.

At the moment of writing this, VMWare vSphere ESXi 6.7 is not supported on HP’s Microserver prior to Gen9. But “not supported” means that there’s no official release, it does not mean “not doable”.

I’ve accomplish this upgrade but follow this procedure at your own risk and ALWAYS backup your data before upgrading.

So here is the procedure I’ve followed to have a fully functional installation of ESXi hipervisor on a legacy Hewlett-Packard GEN8 Microserver GT2020T.

1. Download offline packages

You can download Offline Packages Bundle directly from WMWare’s website. Make sure you download the ZIP FILE.

2. Upload the package ZIP file to a local Datastore

Upload the Zip file to a local datastore. The latest version currently available was released on April 2019 (ESXi HPE Custom 6.7 U1 update 1).

Upload the offline bundle ZIP file.

3. Perform the upgrade process

To acomplish this task, you must enable the SSH in the server. Log in as root and execute the following command. Please note that you must change [datastore] to your actual datastore name without brackets.

# esxcli software profile update -d /vmfs/volumes/[datastore]/VMware-ESXi-6.7.0-Update1-11675023-HPE-Gen9plus-670.U1. -p HPE-ESXi-6.7.0-Update1-Gen9plus-670.U1.

-d: Path to the packages source (zip file)
-p: Specifies the new 'profile' of your hypervisor's installation.

If no errors are shown, your system has been upgraded, you only need to restart your server.

# reboot -f


This procedure upgrades ESXi 6.x to 6.7 on HP Microserver Gen8 and older machines, however you verify wich drivers are currently being used. If you are running on ESXi on a SSD, since the SCSI55 driver can lead to poor write speeds on SSDs, consider replacing it with to the HP-OEM88 driver.
