vSphere Lifecycle Manager enables you to manage ESXi hosts and clusters with images or baselines. You can set up an image at the cluster level and you use the image to manage all hosts in the cluster collectively. You can use baselines with individual ESXi hosts and with all other inventory objects that contain ESXi hosts.

To manage a all ESXi hosts in a cluster with a single image, you have two options.
  • Set up an image for the cluster during the creation of the cluster
  • Skip setting up an image for the cluster and switch from using baselines to using images at a later time.
For more information about creating a cluster that uses a single image, see the vCenter Server and Host Management documentation.

For more information about switching to vSphere Lifecycle Manager images, see Switching from Baselines to Images.

To manage a cluster with baselines and baseline groups, you must skip setting up an image during the creation of the cluster.
