VMware ESXi 6.7 Update 1 Upgrade

So, I’m done with my vCenter upgrade, posted her: VMware VCSA 6.7 U1 Update Now I will proceed and upgrade the ESXi-hosts.

The first step I need to take before I can begin upgrading the hosts, is to check that my hosts’ hardware is compatible with the new ESXi-version: VMware Compatibility Guide

The next step for me now is to upgrade the ESXi-hosts. For this task I will use VMware Update Manager. So i will head over to MyVmware and download the Lenovo custom ISO for my ESXi-hosts.

In vCenter i see that my existing ESXi-build is 9484548, while the new is 10302608.

To be able to use VMware Update Manager for updating the ESXi, I first have to import the new ESXi-image. Click ESXi images

I browse to my newly downloaded ISO and click “Import”

Once imported, it will show up in my ESXi images list below

Next I create a new Baseline for the ESXi upgrade

The new baseline will appear with the rest of available baselines in VMware Update Manager

Now I will attach the new baseline to my ESXi-hosts

I choose my baseline and click “ATTACH”

I do “Check Compliance” to scan the ESXi-host for update-compliance

Before starting Remediation I do the Pre-check, no errors found.

Next step, I put the host in Maintenance Mode

Once the host is in Maintenance Mode, I choose my new baseline and start “Remediate”

I monitor the remediate-task and once the host is rebooted I can verify that the new host is updated to the correct version.

Now I can proceed and patch the rest of my ESXi-hosts. Once that is done I will proceed with updating VMware Tools in my virtual machines and templates. This i will cover in my next post here: VMware vSphere 6.7 Update 1 Virtual Tools Upgrade
