In this post we will go through using vSphere Lifecycle Manager VLM to upgrade an ESXI host from 6.7 to 7.0. Lifecycle Manager replaces vSphere Update Manager in vCenter server 7.0 the process is pretty much the same as in VUM.
Before upgrading to a new version of ESXI first step should be to check VMware compatibility, this can be done by either checking the VMware compatibility matrix.
Or in VLM we can now use Hardware compatibility, This syncs a list of compatible hardware and this can then be checked directly on the host to verify if the ESXI host hardware is supported.
To check using VLM, Open the vSphere web client > Menu > Lifecycle Manager
We then need to sync the hardware compatibility list. Click Actions > Sync HCL
Once synced we can run a compatibility check from the Host > Updates > Hardware Compatibility
After the compatibility is all confirmed and no issues are found, we can go ahead with the upgrade.
Next we need to download the ISO image for ESXI 7.0 that will be imported to VLM and used in the upgrade baseline.
To import the ISO go back to VLM > Imported ISOs > Import ISO
Click browse and select the ESXI ISO that was downloaded earlier.
The ISO will then start to import.
The ISO should now show under Imported ISOs
Next we need to create a new upgrade baseline, this can either be done under baseline or by selecting the image and clicking on New Baseline.
Give the baseline a name
Select the ISO to be used
Click next and finsh off the baseline
Check baselines to confirm the creation has completed.
The baseline can be assigned to the host individually or the cluster. I am going to apply to the cluster. Go to the Cluster and select Updates > Attach.
Select the upgrade baseline.
We can check the compliance for the baseline for all host in the cluster.
To remediate you can either do this from the cluster or on the individual host. I will remediate from the host itself.
Go to the host, Select Updates > Baseline > Upgrade Baseline > Remediate
Accept the end user agreement.
The upgrade will do a remediation pre check before allowing the upgrade.
Once you click Remediate, the upgrade task will start
The host should now reboot and start the upgrade.
When we check the baseline the host should now show as compliant and running ESXI 7.0.
Upgrading a host using VLM is a straight forward process and makes it easy to keep your ESXI host at the latest release version.
