Working…
Why now
The Broadcom shift changed the maths
Costs went up, sharply.
Per-core subscription pricing with a 72-core minimum reshaped budgets for mid-market environments overnight.
Assessment is still manual.
Most teams still scope migrations with RVTools exports and spreadsheets, checking compatibility by hand, VM by VM.
The blockers are invisible until they bite.
Physical RDMs, multi-writer disks, PVSCSI controllers and interface renaming don’t surface until a migration is already underway.
How it works

Read the report
Risk score, every finding with remediation steps, environment summary, and three-year cost exposure.
The report
What the report covers
Risk score per VM
48 rules across six categories, weighted by severity and scored 0–100.
Migration blockers
Physical RDMs, multi-writer shared disks, fault tolerance, and other configurations that stop automated migration outright.
Network identity risks
Interface renaming and MAC-based DHCP reservations, the most common cause of a VM coming up with no network after a move.
Snapshot and capacity analysis
Chain depth, snapshot age, datastore headroom, and the storage you’d recover by consolidating.
Environment summary
VM, host and cluster counts, guest OS breakdown, provisioning ratios, hardware versions, controller types.
Broadcom cost exposure
Three-year projection with correct core-minimum handling, compared against alternative platforms.
Remediation guidance
Every finding includes the specific steps to resolve it, branched by guest OS where it matters.
PDF and CSV export

Sample
See it before you upload anything
A full report generated from a 412-VM environment — every finding, every remediation step, and the three-year cost model. No email required.
Vendor neutrality
Every other assessment tool has a destination in mind
That’s not a criticism — vendors build tools to sell platforms, and their tools are good at it. But if you’re deciding where to go, you want an assessment that isn’t pointed anywhere in particular.
| Tool | Points toward | Delivered as |
|---|---|---|
| AWS Transform | AWS | Self-service |
| Red Hat migration tooling | OpenShift Virtualization | Consulting engagement |
| Nutanix Collector | Nutanix | Free tool |
| RVTools | Nothing — raw inventory only | Free tool |
| PolyVirt | Whatever actually fits your environment | Free, no account |
We model Proxmox, Nutanix AHV and Hyper-V as targets, and we’ll tell you when staying put is the cheaper answer.
What it costs
Free, and not a trial of anything
Every check, the wave plan and every export, with no account and no upload. It parses in your browser, so there is no cost we are absorbing until you convert — which is why it stays free rather than free-for-now.
Paid tiers are planned and not built. No price, no waiting list, no beta. What they would cover:
Multi-environment comparison
Every estate you look after in one view, rather than one report at a time.
Scheduled re-assessment
The same export run again on a schedule, with the difference called out.
vCenter-connected checks
The four checks no RVTools export can answer, including GPU passthrough.
FAQ
Common questions
Is my data uploaded anywhere?
No. The free analyzer parses your RVTools file entirely in your browser using JavaScript. The file never touches a server, and nothing is stored. You can verify this by watching your browser’s network tab, or by disconnecting from the internet after the page loads.
What is RVTools and where do I get an export?
RVTools is a widely used free utility that reads a vCenter or ESXi inventory and exports it to Excel. Run it against your environment and export to .xlsx, then drop that file here.
Which vSphere versions are supported?
Any version RVTools can read — 6.5 through 8.x.
Which migration targets do you model?
Proxmox VE, Nutanix AHV and Hyper-V. The risk rules cover configurations that affect all KVM-based and Hyper-V targets.
How is this different from what RVTools already gives me?
RVTools gives you accurate raw inventory across twenty-odd spreadsheet tabs. It doesn’t interpret it. PolyVirt applies 48 migration-specific rules, scores each VM, explains why each finding matters, and tells you how to resolve it.
What can’t an RVTools export tell you?
It’s a point-in-time configuration snapshot with no performance history, so it can’t determine whether VMs are correctly sized or model actual migration downtime. It also omits several vCenter properties that affect migration outcomes. For that, a direct collector run against vCenter is needed.
How accurate is the Broadcom cost estimate?
It’s based on published list pricing and your actual core count, including correct handling of the 72-core minimum. Real pricing depends on your agreement, term and partner discount, so treat it as a directional estimate rather than a quotation.
Do I need to install anything?
No. It runs in the browser.
Is there an API?
Not yet.
