You can create custom patches, extensions, and upgrade baselines to meet the needs of your specific deployment by using the
New Baseline wizard. You create and manage baselines in the Update Manager Client Administration view.
Create and Edit Patch or Extension Baselines You can remediate hosts against baselines that contain patches or extensions. Depending on the patch criteria you select, patch baselines can be either dynamic or fixed.
Create and Edit Host Upgrade Baselines You can create an ESX/ESXi host upgrade baseline by using the New Baseline wizard. You can create host baselines with already uploaded ESXi 5.5 images.
Create and Edit a Virtual Appliance Upgrade Baseline A virtual appliance upgrade baseline contains a set of updates to the operating system and to the applications installed in the virtual appliance. The virtual appliance vendor considers these updates an upgrade.
Delete Baselines You can delete baselines that you no longer need from Update Manager. Deleting a baseline detaches it from all the objects to which the baseline is attached.
