  3. VMware to Azure Migration

VMware to Azure Migration USA: VMware to Azure migration, planned, rehearsed, and cost-modelled.

VMware to Azure migration is the planned re-platforming of vSphere workloads onto Microsoft Azure, typically driven by Broadcom's 2024 acquisition, 10x licensing increases, or end-of-support timelines. GR IT Services runs the discovery, builds a TCO model that includes Azure VMware Solution vs Azure native rehost, rehearses the cutover, and delivers under a written SLA.

What we deliver

Nine capabilities for a VMware-to-Azure program.

Whether the answer is Azure VMware Solution (AVS), native Azure rehost, or a hybrid, our team has run the path before.

Discovery & dependency mapping

Inventory every VM, application, network dependency, and storage workload. Output: a written assessment with risk-flagged migration waves and a cost-to-migrate range.

TCO and Broadcom-exit modeling

Model your current VMware spend against AVS, native Azure rehost, and stay-on-VMware scenarios over 1, 3, and 5 years. Output: a board-ready TCO comparison and license-rationalisation plan.

Azure VMware Solution (AVS)

For workloads that benefit from minimal re-engineering: AVS gives you a vSphere environment inside Azure with VMware tools intact. We provision, configure, and govern.

Azure native rehost (lift-and-shift)

For workloads ready to leave VMware: Azure Migrate-driven rehost to Azure IaaS with right-sized VMs, managed disks, and modernization candidates flagged for phase 2.

Network & security re-architecture

Azure Virtual Network, ExpressRoute, Azure Firewall, NSGs, application gateways. Lift the NSX rules from on-prem into Azure-native policy where appropriate.

Storage migration

vSAN, VVOLs, NFS shares mapped to Azure Managed Disks, Azure NetApp Files, or Blob storage with cool/archive tiers. Latency-sensitive workloads kept on Premium SSD v2.

Identity, RBAC, governance

Entra ID integration, Azure RBAC role design, Azure Policy guard-rails, Defender for Cloud baselines. Day-1 governance, not bolted on later.

Cutover orchestration

Wave-based cutovers, Azure Site Recovery replication, dress rehearsals, and a rollback plan. Production cutovers run with senior engineers on-call.

Post-migration optimization

FinOps tagging, right-sizing reviews, Reserved Instance / Savings Plan strategy, Hybrid Benefit application, autoscale design. 25-40% cost cuts in the 90 days after cutover.

Why GR IT for VMware exit

Four reasons US enterprises pick us for the Broadcom-exit program.

VMware-to-Azure is a politically charged migration in 2026: license renewal deadlines, board-level cost pressure, and architecture choices that matter. Here is what makes our delivery different.

40+ VMware estates assessed

Pattern recognition matters. We have seen the application portfolios, the storage anti-patterns, the network-dependency surprises. We tell you what is hard to migrate before the project ramps.

TCO is the deliverable

Most VMware-exit projects fail at the budget stage. We model AVS vs native rehost vs stay-on-VMware before you commit; the TCO model survives leadership change because it is a written artefact.

US delivery, Azure-certified bench

Azure-certified engineers (AZ-104, AZ-305, AZ-700) on the US delivery bench. ExpressRoute, AVS, and Azure Migrate hands-on, not just slide-deck familiarity.

No reversibility surprises

We document what we change, where data lands, and what the rollback path is. If the cutover wave goes wrong at 02:30, the rollback is in the runbook, signed off in advance.

Industries running VMware-to-Azure

Where we see the strongest Azure migration case.

Six US sectors where Broadcom's licensing changes have triggered active migration programs in the past 18 months.

Financial services

Mid-market banks, broker-dealers, and asset managers running 200-2,000 VMs facing 3-5x VMware renewal quotes. AVS for regulated workloads, native rehost for the rest.

Healthcare & life sciences

Hospital systems and biotech with EHR, PACS, and lab-informatics workloads. HIPAA-compliant migration paths with PHI sensitivity preserved through cutover.

Professional services

Law firms, accountancies, consultancies running practice-management and document systems on VMware. Often paired with an M365 SharePoint migration in the same program.

Manufacturing & supply chain

Mid-market manufacturers running ERP (SAP, Oracle, Dynamics 365 FO), MES, and warehouse-management on VMware. OT/IT segmentation preserved through migration.

Retail & hospitality

Retailers and hospitality groups running POS back-of-house, inventory, and CRM systems on VMware across many sites. Centralisation to Azure with edge gateways.

Tech & SaaS

SaaS companies migrating multi-tenant workloads off VMware to Azure-native (AKS, App Service, Cosmos DB) to escape VMware costs and gain platform-engineering velocity.

AVS vs native rehost vs stay-on-VMware

Three viable paths - which one is right for your estate?

There is no single right answer. We pick the path per workload, often a mix. The honest comparison:

How a program runs

Assessment to cutover in five phases.

A typical mid-market VMware estate (50-500 VMs) runs 4-9 months end-to-end. Every program runs the same five phases with written gating criteria.
  1. 1

    Discovery & TCO model

    3-5 weeks

    Inventory every VM, application, and dependency. Build the TCO model: AVS vs native vs stay-on-VMware. Output: written assessment, target-state architecture, board-ready cost-and-risk case.

  2. 2

    Foundation build

    3-5 weeks

    Azure landing zone, network architecture (ExpressRoute or VPN), identity integration, governance baselines, monitoring and backup tooling. AVS clusters or AKS provisioning where required.

  3. 3

    Wave migration

    8-24 weeks

    Migrate in 4-12 workload waves grouped by application affinity. Azure Site Recovery or Azure Migrate replication per workload. Cutover rehearsals before every production wave.

  4. 4

    Hypercare

    4 weeks

    Senior engineers on-call for the four weeks after final cutover. P1 incident SLA cut to 5 minutes. Daily check-ins until incident volume normalizes.

  5. 5

    Optimization & handover

    Continuous

    FinOps tagging review, right-sizing, RI/Savings Plan strategy, Hybrid Benefit application. Handover to your team or transition into our managed Azure operations.

Common questions

VMware to Azure migration, frequently asked.

Broadcom's 2024 acquisition of VMware ended the perpetual-license model and consolidated the product line into two subscription bundles (VCF and vSphere Foundation). Renewal quotes have come in at 2-5x prior pricing for many customers. US enterprises are reacting in three ways: renegotiate, partial-exit (AVS), or full-exit (Azure-native rehost). We run the analysis with you.

AVS is best when you want minimal application change, latency-sensitive workloads, and continued vSphere/NSX operating model. Native rehost is best when applications are stable but ready to escape VMware tooling. In practice, most mid-to-large estates use both: AVS for the regulated / latency-sensitive 20-30%, native rehost for the rest, and Azure-native (PaaS, AKS) for new builds.

Four to nine months for a 200-VM mid-market estate. Drivers: dependency complexity (application portfolio mapping), data-volume size (TB of storage), regulatory constraints (PCI / HIPAA scope), and parallelism (how many waves run concurrently). We deliver a written timeline in the discovery phase with monthly milestones.

For a 200-VM estate, the migration program (discovery + foundation + wave migrations + hypercare) is scoped per engagement based on VM count and complexity, plus AVS or Azure consumption costs. Most clients see ROI within 12-18 months through license cost reduction alone, with further savings from FinOps optimization in year 2.

Veeam works fine on AVS and Azure native (Veeam supports both). Zerto v10 supports Azure native and AVS for DR. NetBackup runs on Azure compute. We map the tooling in discovery; some clients replace third-party DR/backup with Azure Site Recovery + Azure Backup at this stage.

Often yes, in your favor. Azure Hybrid Benefit lets you bring eligible Windows Server and SQL Server licenses with active Software Assurance to Azure at significant discount. We audit your licensing position in discovery to maximize Hybrid Benefit application.

Yes. Many clients keep some workloads on-prem (regulated, edge, specialty hardware) and migrate the rest. Azure Arc gives you a single management plane across on-prem and Azure resources. We design the hybrid network with ExpressRoute or Azure Virtual WAN.

Managed by waves, rehearsals, and Azure Site Recovery replication. Each workload runs a dress rehearsal before production cutover; rollback is documented in the runbook. Mid-market estates typically see less than 30 minutes of user-visible disruption per wave. Cutovers run outside business hours with senior engineers on-call.

Yes, as a Microsoft CSP partner we can place your Azure consumption with consolidated billing, negotiate Reserved Instance / Savings Plan purchases, and apply Hybrid Benefit credits. Alternatively, your existing EA can be honoured and we operate alongside.
