Prior to vSphere 7.0, ESXi lifecycle management has been provided by vSphere Update Manager (VUM), which has been around for more than a decade plus and is most likely what you are still using today. With the release of vSphere 7.0, VMware introduced a brand new lifecycle management solution for ESXi called vSphere Lifecycle Manager (vLCM), which you can read more about HERE.
While VMware has made it clear that vLCM will be the future going forward for ESXi lifecycle management, we also understand that most customers will still be using the existing VUM-based solution and we wanted to make sure it was easy to transition between the two solutions, especially within the vSphere UI.
An interesting question was recently brought up was how to determine whether a vSphere Cluster was using the new vLCM solution based on desired images versus VUM, which uses baselines?
Note: If you are not familiar between vLCM Desired Image and VUM Baselines, be sure to check out this helpful resource HERE.
