The first critical steps in enabling that were actually delivered in WS2012 Hyper-V:<\/p>\n<ul>\n<li>VHDX: You\u2019re a sucker if you\u2019re still deploying passthrough disks.&#160; You\u2019re being negligent, in my opinion, if you\u2019re a so-called-expert (like a consultant) and still typing your customers\u2019 VMs to specific hardware devices.&#160; I won\u2019t hold any punches on this, and I don\u2019t have time for defensive excuses. <\/li>\n<li>Shared-Nothing Live Migration: We can move virtual machine files and the VMs themselves between any mix of clustered and non-clustered hosts. <\/li>\n<\/ul>\n<p>That latter one is important, because we still cannot do an in-place upgrade of a Failover Cluster.&#160; Yes, Microsoft has heard the feedback.&#160; Just give them more of it if you are talking to them directly, especially if it\u2019s a local\/visiting rep from the Windows Server &amp; System Center product group (giving feedback to a person from the local subsidiary is pointless).<\/p>\n<p>We can use cross-platform Live Migration from WS2012 Hyper-V to WS2012 R2 Hyper-V to get zero-downtime \u201cupgrades\u201d.&#160; Scenarios include:<\/p>\n<ul>\n<li>Doing a Shared-Nothing Live Migration from a WS2012 Hyper-V cluster to a Hyper-V Server 2012 R2 cluster <\/li>\n<li>Performing a Live Migration from a non-clustered Hyper-V Server 2012 host to a non-clustered WS2012 R2 Hyper-V host where they share common SMB 3.0 (WS2012\/WS2012 R2) storage. <\/li>\n<li>And more!<\/li>\n<\/ul>\n<p><a href=\"https:\/\/aidanfinn.com\/wp-content\/uploads\/2013\/06\/image9.png\"><img loading=\"lazy\" decoding=\"async\" title=\"image\" style=\"border-top: 0px;
