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.

Nine capabilities for a VMware-to-Azure program.
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.
Four reasons US enterprises pick us for the Broadcom-exit program.
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.
Where we see the strongest Azure migration case.
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.
Three viable paths - which one is right for your estate?
| Feature | Stay on VMware Renew with Broadcom | Azure VMware Solution (AVS) vSphere on Azure | Azure-native rehost IaaS / PaaS |
|---|---|---|---|
Re-engineering required | None | Minimal | Moderate |
Time to first workload | 0 (already running) | 4-8 weeks | 8-16 weeks |
License cost trajectory | Rising 2-5x at renewal | Microsoft-bundled, predictable | Pay-as-you-go + RI savings |
Best for workloads | Frozen / no roadmap | Lift-and-shift, low-touch | Cloud-native candidates |
VMware tools / NSX / vSAN | Native | Native (Microsoft-managed) | Replaced with Azure equivalents |
Modernization runway | Limited | Good | Excellent |
Operating-model change | None | Minimal | Significant |
Typical 3-year TCO vs status quo | Baseline | −20 to −40% | −40 to −60% |
Assessment to cutover in five phases.
- 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
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
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
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.
