Lifecycle Management (LCM) enables you to perform automated updates on Cloud Foundation components (SDDC Manager, HMS, and LCM), VMware components (vCenter Server, ESXi, and NSX), and third party tools.
SDDC Manager is pre-configured to communicate with the VMware software repository. The high level update workflow is described below.
Receive notification of update availability.
Download update bundle.
Select update targets and schedule update.
Update is applied to the selected targets at the scheduled time.
Even though SDDC Manager may be available while the update is installed, it is recommended that you schedule the update at a time when it is not being heavily used.
For an unassigned host (host in the capacity pool that is not part of a workload domain), you must bring the unassigned host into a workload domain, and then update the domain as described in Update a Workload Domain.
When you delete a workload domain, it is recommended that you decommission the host, image it with the current, upgrade ESXi version, and then perform the add host procedure. This ensures that when the hosts are required for new workload domain, they are ready and their ESXi versions up to date. (When a workload domain is deleted, the hosts revert to the ESXi version their rack was originally imaged with.)
