But I do not have an extremely customized set up. I first install in a VM to update and verify my install flow, then on a > test machine - then I deploy it everywhere. There is plenty of support > overlap to do that at my own pace. A variation on that theme is to have a thin OS running a hypervisor on the bare hardware and run everything else in a VM. VMs make upgrades really painless, especially if using tools like Vagrant and a configuration manager like Ansible. But even if you’re not using those tools, VMs are nice for snapshotting, upgrading, testing, cloning, migrating, and reverting, if necessary. Of course, you could always use your favorite backup/restore utility, if not using a VM. Regards, - Robert
