You can use vSphere Update Manager to perform orchestrated upgrades of the
ESXi hosts in your vSphere inventory by using a single upgrade baseline, or by using a baseline group.
About this task
This workflow describes the overall process to perform an orchestrated upgrade of the hosts in your
vSphere inventory. vSphere Update Manager 6.0 supports host upgrades to ESXi 6.0 for hosts that are running ESXi 5.x.
You can perform orchestrated upgrades of hosts at the folder, cluster, or data center level.
The last two steps in this procedure are alternatives. Choose one or the other.
Configure Host Maintenance Mode Settings ESXi host updates might require that the host enters maintenance mode before they can be applied. Update Manager puts the ESXi hosts in maintenance mode before applying these updates. You can configure how Update Manager responds if the host fails to enter maintenance mode.
Configure Cluster Settings For ESXi hosts in a cluster, the remediation process can run either in a sequence or in parallel. Certain features might cause remediation failure. If you have VMware DPM, HA admission control, or Fault Tolerance enabled, you should temporarily disable these features to make sure that the remediation is successful.
Enable Remediation of PXE Booted ESXi Hosts You can configure Update Manager to let other software initiate remediation of PXE booted ESXi hosts. The remediation installs patches and software modules on the hosts, but typically the host updates are lost after a reboot.
Import Host Upgrade Images and Create Host Upgrade Baselines You can create upgrade baselines for ESXi hosts with ESXi 6.0 images that you import to the Update Manager repository.
Create a Host Baseline Group You can combine one host upgrade baseline with multiple patch or extension baselines, or combine multiple patch and extension baselines in a baseline group.
Attach Baselines and Baseline Groups to Objects To view compliance information and remediate objects in the inventory against specific baselines and baseline groups, you must first attach existing baselines and baseline groups to these objects.
Manually Initiate a Scan of ESXi Hosts Before remediation, you should scan the vSphere objects against the attached baselines and baseline groups. To run a scan of hosts in the vSphere inventory immediately, initiate a scan manually.
View Compliance Information for vSphere Objects You can review compliance information for the virtual machines, virtual appliances, and hosts against baselines and baseline groups that you attach.
Remediate Hosts Against an Upgrade Baseline You can remediate ESXi hosts against a single attached upgrade baseline at a time. You can upgrade all hosts in your vSphere inventory by using a single upgrade baseline containing an ESXi 6.0 image.
Remediate Hosts Against Baseline Groups You can remediate hosts against attached groups of upgrade, patch, and extension baselines. Baseline groups might contain multiple patch and extension baselines, or an upgrade baseline combined with multiple patch and extension baselines.
