That removes a data-transfer stage, not the work and risk of migrating an application. Eligibility, configuration, cutover, service validation and rollback still need to be planned.
What “zero-copy” means in this workflow
In its September 29, 2026 description of Move 6.3, Nutanix documents a specific integration with Everpure FlashArray. For eligible VMware vVol-based virtual disks stored on the same FlashArray, Move invokes the array’s cloning APIs to create disks for the Nutanix target. The data remains on the array rather than being seeded over the network as part of a conventional copy workflow. Nutanix’s Move 6.3 description is about this particular path, not a claim that all VMware-to-Nutanix migrations avoid data movement.

The target Nutanix compute cluster is registered with the external FlashArray holding the VMware VM disks and connects to it using NVMe/TCP. Move is configured with the array, VMware source and Nutanix target. It identifies VMs that can be selected and flags ineligible VMs with a reason. Nutanix does not publish a universal compatibility matrix in the cited description, so confirm eligibility for the actual workload and configuration before defining scope or schedule.

- Stop the source workload: Move shuts down the source VMs and disconnects their virtual NICs.
- Prepare target VMs: Move creates target VMs with comparable configuration and placeholder disks.
- Clone disks on the array: Move calls FlashArray APIs to clone the VM disks for the target.
- Start and prepare the target: Move starts the target VMs and performs the preparation needed for the migrated workloads.
For this zero-copy path, Nutanix says there is no final delta data sync and no vDisk consolidation step. Those details distinguish it from other Move workflows; they do not mean cutover or downtime planning disappears. The exact service interruption depends on the environment and the work required to bring the target application into service.
#1 Best Overall
Zero-copy does not validate the application
A cloned disk is not proof that a service is ready for users. Guest configuration, target networking, application dependencies, data consistency and business sequencing still matter. Nutanix’s migration guidance calls for environment and dependency assessment, runbooks, prerequisite checks, rollback planning, user acceptance testing and stakeholder sign-off. See Nutanix’s VMware-to-Nutanix migration guidance.
Before cutover, map target networks and review VM settings, guest preparation and dependencies. Set a maintenance window and agree who will verify the service, what constitutes acceptance, and who can authorize a rollback. After cutover, test the application at the level users and dependent systems rely on—not only whether the VM powers on.
Rank #2
Source retention helps, but rollback still needs a plan
Nutanix says the source VMs remain in the source environment after this cutover, with a note added and their virtual NICs disconnected. Its broader guidance describes a common VM-level rollback pattern: power off the AHV copy and power the original source VM back on. Neither fact amounts to a universal one-click rollback. If the application accepts writes or changes state after cutover, simply restarting the old VM may leave data or transactions out of sync. Agree on source handling, decision points and recovery steps before migration, including how post-cutover changes will be handled.
Zero-copy versus other Nutanix Move workflows
Nutanix’s general Move product page describes broader migration capabilities, including pre-seeding data days or weeks ahead, pre-cutover workload testing, network mapping, a final delta sync and automated cutover. Those are general Move capabilities; they should not be blended into the narrower zero-copy sequence documented for eligible VMware vVol disks on Everpure FlashArray.
| Workflow | Data handling | Final delta sync | Scope |
|---|---|---|---|
| Zero-copy integration | FlashArray clones eligible VMware vVol-based VM disks in place through array APIs; the described workflow avoids data seeding. | No, according to Nutanix’s description of this path. | Eligible VMware vVol disks on the specified Everpure FlashArray setup. |
| General Move workflows | May pre-seed data ahead of cutover and copy changes later. | Described as part of the general workflow; applicability depends on the migration path. | Move supports multiple source environments, including VMware vSphere, Hyper-V and AWS; this does not establish zero-copy support for each. |
A practical readiness checklist
- Confirm the source hypervisor, VMware vVol configuration, FlashArray, target cluster and NVMe/TCP requirements against current product documentation.
- Use Move’s eligibility results to identify which VMs are in scope and investigate each rejection reason.
- Review guest preparation, network mappings, VM settings, application dependencies and the maintenance window.
- Define application-level validation and obtain the necessary operational or business sign-off.
- Document rollback steps, decision authority and how the source VM and any post-cutover application changes will be handled.
How fast is it?
Nutanix says migrations can complete rapidly, “often in minutes depending on the environment, configuration, and workload characteristics.” This is a qualified vendor characterization, not a measured benchmark or a guaranteed completion time. It should not be used as a substitute for sizing a maintenance window around eligibility checks, cutover, application validation and the agreed recovery plan.
