Ask three vendors what your migration will cost and you'll get three numbers that aren't comparable, one quotes only licensing, one only professional services, one a "starting at" figure that assumes everything goes perfectly. This guide puts all the line items in one place so you can build a real budget.

The per-VM framing
Per-VM cost is the most honest way to compare proposals, because it forces every cost into one denominator. What moves a VM from the bottom of the range to the top:
| Complexity tier | Typical cost per VM | What's in this tier |
|---|---|---|
| Simple | $700–$1,000 | Stateless app/web servers, file servers, dev/test; few dependencies; modern OS |
| Moderate | $1,000–$1,500 | Standard business apps, domain controllers, mid-size databases; some interdependencies |
| Complex | $1,500–$2,100+ | Clustered databases, ERP, legacy OS, hard-coded IPs, compliance scope, tight downtime windows |
Most environments are a mix, commonly 50/35/15 across the tiers, which is why blended budgets tend to land near $1,000–$1,300 per VM.
The full line-item breakdown
Illustrative ranges for a 100-VM mid-market migration. Treat these as planning bands, not quotes.
| Line item | Typical range (100 VMs) | Notes |
|---|---|---|
| Discovery & assessment | $10k–$30k | Inventory, dependency mapping, app owner interviews; often credited back by the migration partner |
| Target platform licensing (yr 1) | $0–$150k+ | Proxmox near-zero; Hyper-V often covered by existing Windows licensing; Nutanix and hyperscaler VMware at the top |
| Hardware (if refreshing) | $0–$300k | $0 for cloud/managed targets or reusing hosts; HCI nodes at the top end |
| Migration tooling | $0–$25k | Nutanix Move and Proxmox importers are free; HCX bundled with some targets; third-party tools priced per VM |
| Professional services / labor | $40k–$120k | The largest controllable item; internal staff time counts even when it isn't invoiced |
| Retraining & certification | $5k–$25k | Admin training on the new stack; backup/DR tooling changes included |
| Parallel-run overlap | 1–3 months dual cost | You pay for both environments during waves, budget it explicitly |
Hidden costs that blow up budgets
- Application testing and validation. The single most underestimated item, commonly 25–50% of total labor. Every app owner sign-off takes calendar time and meetings.
- Network rework. Re-IP'ing, firewall rules, load balancer configs, VPN endpoints. Hard-coded IPs in legacy apps turn a simple move into a project.
- Backup and DR re-platforming. Your Veeam/Zerto/Commvault setup is built around vSphere APIs; the target platform may need new licensing or a different product.
- Storage egress and replication transfer. Mostly a cloud-target issue; seeding hundreds of TB has both bandwidth cost and calendar cost.
- Rollback insurance. Keeping source hosts powered and licensed until validation completes, which can collide with your VMware renewal date if you cut timing too fine.
- Staff backfill and overtime. Your team still has day jobs during cutover weekends.
The comparison nobody quotes: staying on VMware via a managed provider
A platform migration isn't the only way off Broadcom's pricing. Moving your environment to a managed VMware provider (a VCSP partner such as 11:11 Systems, Expedient, or TierPoint) keeps vSphere intact, workloads move with vMotion/HCX rather than being converted, so the "migration" cost is a fraction of a replatform:
| Path | One-time cost (100 VMs, typical) | Disruption | Where the savings come from |
|---|---|---|---|
| Replatform (Proxmox/Hyper-V/Nutanix) | $70k–$210k | Moderate–high | Eliminating Broadcom licensing entirely; biggest 5-year TCO win |
| Managed VMware provider | $15k–$60k | Low | Provider's VCSP scale pricing + retiring your hardware/data center spend |
| Hyperscaler VMware (AVS/GCVE) | $30k–$80k | Low | Usually none vs. Broadcom direct, you pay for speed and consolidation, not savings |
| Renew with Broadcom | $0 | None | None, this is the baseline everyone else beats |
Which path wins depends on horizon: managed VMware delivers savings fastest; a replatform usually wins by year 3–5, especially when a hardware refresh was due anyway. Our on-prem vs. cloud guide covers the TCO logic, and the comparison matrix ranks all eight paths.
Building the business case
Frame it as 3-year TCO, not migration price:
- Status quo: (Broadcom renewal × 3) + hardware refresh + the risk premium of doing this again at the next renewal.
- Each alternative: one-time migration cost + (new platform run cost × 3).
Most mid-market environments facing a 2–5× renewal find at least one alternative that pays back inside 12–24 months. Run your own numbers in the free cost calculator, it takes about two minutes, or skip straight to a priced, advisor-built comparison with a free assessment.
