Baseline groups can contain patch, extension, and upgrade baselines. The baselines that you add to a baseline group must be non-conflicting.

A baseline group is limited to a combination of patches, extensions, and upgrades. The following are valid combinations of baselines that can make up a baseline group:

  • Multiple host patch and extension baselines.

  • One upgrade baseline, multiple patch and extension baselines.

    For example, one ESX/ESXi upgrade baseline and multiple ESX/ESXi patch or extension baselines.

  • Multiple upgrade baselines, but only one upgrade baseline per upgrade type (like VMware Tools, virtual machine hardware, virtual appliance, or host).

    For example, VMware Tools Upgrade to Match Host baseline, VM Hardware Upgrade to Match Host baseline and one VA Upgrade to Latest baseline. You cannot create a baseline group containing two virtual appliance upgrade baselines.
