Had a question on Nutanix's Metro Availability RTO for vms I was hoping someone could clarify. If you have a vm configured in Metro Availability and you have a DR situation that takes down the primary site or you proactively fail over the vm, in the case of a planned data center migration what happens to the state of the vm during that transition period? It is my undestanding the vm will temporarily drop while it is brought back online at the secondary site. Is this true? If true, could someone clarify what actually happens to the vm? Does it power off, etc? The reason I care is we are looking to migrate vms to a new datacenter and if the vm temporarily goes offline it will dramatically change my migration strategy. I was hoping the process would be similiar to a VMware Metro streched cluster where I could just vmotion between sites with no downtime.

If you don't mind, could you check out the Metro Availability best practices guide? http://go.nutanix.com/metro-availability.html
It goes into the exact detail you're looking for regarding planned migration and unplanned failures. I'm the author, so if you have any questions after reading those sections, please post again and I'll answer. But in a nutshell, a planned migration, where you activate the container in the secondary cluster, does require downtime today (VM power cycle). The planned migration scenario should be changing for the better this calendar year, so please let me know if you need more info.
