Most VMware migration cost estimates account for compute, licensing, and professional services. Almost none account for the cost of rebuilding backup and disaster recovery from the ground up.
The standard business case for a VMware migration to Nutanix typically captures compute hardware costs, Nutanix licensing, professional services, and internal team time. It rarely captures the cost of rebuilding backup and disaster recovery infrastructure, and that omission is consistently significant.
What Actually Happens to Backup During a VMware Migration
Most enterprise backup environments are built on platforms certified for VMware vSphere. Veeam, Cohesity, Rubrik, Commvault, and Zerto all support Nutanix AHV, but the path from one to the other requires establishing new backup agents or APIs, redesigning replication topologies, revalidating recovery objectives, and rebuilding the runbooks that on-call teams use when something goes wrong.
While major backup vendors support Nutanix AHV natively, many enterprise customers discovered during migration that their existing backup licensing did not cover AHV workloads. New licensing was required, at costs not included in migration business cases. The CTO Advisor's analysis of migration programs confirms this is a consistent discovery-phase surprise.
The DR Runbook Problem
Disaster recovery runbooks reference VMware-specific tools: vSphere Replication, Site Recovery Manager, snapshot procedures, and vCenter failover sequences. These runbooks do not port. As The CTO Advisor noted, organizations that discover DR runbook dependencies during migration execution face weeks of delay at the worst possible time, when production workloads are in transition.
Zerto and Site Recovery Manager Transitions
Organizations running VMware Site Recovery Manager face a specific challenge. SRM is deeply integrated with vSphere and does not extend to Nutanix AHV. Organizations using SRM for orchestrated failover must identify a replacement replication and orchestration solution before migrating workloads that SRM currently protects.
Zerto is a commonly deployed alternative that supports both VMware and Nutanix environments, making it a viable bridge for organizations managing a hybrid migration state. But deploying Zerto for Nutanix workloads while maintaining SRM for remaining VMware workloads requires parallel replication infrastructure, with its own associated licensing and operational costs.
Building Backup and DR Costs Into the Business Case
Backup and DR costs belong in the migration business case from the beginning: validating backup platform licensing coverage before migration planning is finalized, building DR runbook redesign and testing time into wave plan timelines, and confirming that replication topologies will function as designed in the new environment.
VirtualReady addresses this by mapping backup and DR dependencies as part of its pre-migration analysis. Workloads are flagged for their backup platform, replication configuration, and DR runbook status before wave planning begins.

FREQUENTLY ASKED QUESTIONS
Do major backup platforms like Veeam and Rubrik support Nutanix AHV?
Yes, all major enterprise backup platforms support Nutanix AHV. However, existing VMware-based backup licensing may not automatically extend to AHV workloads. Licensing validation should be completed before migration business cases are finalized.
What happens to VMware Site Recovery Manager during a Nutanix migration?
SRM is specific to vSphere and does not extend to Nutanix AHV. Organizations relying on SRM for DR orchestration must identify and deploy a replacement solution before migrating SRM-protected workloads. Zerto is one commonly used alternative that bridges both environments.
How long does DR runbook redesign and validation take?
A conservative estimate for comprehensive DR runbook redesign and validation is 60 to 90 days per workload tier. For regulated environments that require documented DR testing evidence, this timeline may extend further.
How does VirtualReady help with backup and DR dependency mapping?
VirtualReady maps backup platform configurations, replication topologies, and DR runbook dependencies as part of its pre-migration analysis. Workloads with complex DR requirements are sequenced appropriately and given sufficient time for validation before cutover.
