I see a pre-canned workflow called "Reprovision a host with a new image". I have auto-deploy in my vCenter and can setup an image and ruleset. My question is if this workflow will actually upgrade the ESXi hosts for me? Will it retain all the current settings on the host? I guess I'm looking for a vRO workflow that can upgrade my ESXi hosts to 8.x that someone can just use the context action to perform. Also, will in maintenance mode the host or do I need to setup an pre-workflow to do that operation?
