VMWARE MIGRATION READINESS ASSESSMENT

KNOW WHAT’S IN YOUR ENVIRONMENT BEFORE YOU TRY TO MIGRATE OUT OF IT. NO ACCESS REQUIRED. NO CREDENTIALS EXPOSED.

RACK2CLOUD >_ ARCHITECTURE SERVICES

Know What’s In Your Environment —
Before You Try To Leave It.

Run a local script in your own vSphere environment. Upload a sanitized JSON. Receive a migration readiness score and prioritized remediation plan within 2 business days.

✓ No credentials required ✓ No vCenter access granted ✓ No sensitive data collected

Most VMware environments score below 70. RDM blockers are almost always a surprise.

>_ THE PROCESS

Four Steps. Zero Access Required.

STEP 01
⚡

Run Locally in Your vSphere Environment

Execute the open-source script inside your own authenticated vCenter or ESXi session. Nothing leaves without your review.

STEP 02
🛡️

Script Generates Sanitized JSON

Structural metadata only — counts, booleans, percentages. All VM names, datastore paths, and IP addresses are permanently stripped.

STEP 03
📤

Review & Upload the Payload

Open the JSON in any text editor. Verify it yourself. Then upload with your context — no surprises, no hidden fields.

STEP 04
📋

Receive Your Migration Readiness Brief

A 3-page scored PDF in your inbox within 2 business days — readiness score, storage reclaim analysis, RDM disposition plan, and a Fix This First roadmap.

>_ OPEN SOURCE & AUDITABLE

Read the Script Before You Run It.

Every line of Invoke-R2CVMwareReadiness.ps1 is public on GitHub. No obfuscation. No telemetry. No external network calls beyond the vSphere API — the same API your vSphere Client uses. Run -DryRun to see exactly what would be collected before making a single API call.

The teaser names the domain and the specific count — but not the remediation sequence or migration path. The full brief maps every finding to a ranked fix with effort vs. impact scoring, plus a readiness verdict for Nutanix Move.

>_ SCORE BANDS
85 – 100

Migration Ready

Environment is clean. Proceed to sizing and cutover planning.

70 – 84

Moderate Debt

Addressable gaps. Remediate in parallel with migration planning.

50 – 69

High Debt

Significant blockers present. Remediate before scheduling cutover.

< 50

Critical

Do not begin migration. High probability of mid-flight failure.

>_ THE BRIEF

Three Pages. Every Finding Mapped to a Fix.

>_ COMMON QUESTIONS

Before You Ask.

  • Q Is my data safe? What exactly are you receiving?
    We receive a JSON file containing only structural metadata — counts, booleans, and percentages. The script permanently strips all VM names, datastore paths, IP addresses, credentials, and tag values before writing the file. Open the JSON in a text editor before uploading — you can verify every field yourself.
  • Q Do you need access to my vSphere environment?
    No. The script runs inside your own authenticated vCenter or ESXi session. We never request credentials, service account access, or any form of environment access. You run the script, you review the output, you decide whether to upload it.
  • Q What does the script actually collect?
    Five domains: Snapshots (count, total GB, chain depth, oldest age), VMware Tools (running state and version currency), Zombie VMs (powered-off count, allocated storage, owner tag coverage), ISO Hygiene (mounted and orphaned ISO counts and GB), and RDM Audit (total count, physical vs virtual breakdown, migration blocker flag). Run .\Invoke-R2CVMwareReadiness.ps1 -DryRun to see every field before execution.
  • Q How long does the script take to run?
    Typically 5–15 minutes depending on VM count and datastore size. The ISO orphan scan and per-VM snapshot walk are the slowest steps in large environments. Let it run to completion — the terminal output will confirm when the payload is written.
  • Q What does the 3-page brief actually look like?
    Page 1 is your Migration Readiness Score, risk band, and domain-level findings. Page 2 is your storage reclaim analysis — snapshot waste, zombie VM storage, and orphaned ISO reclaim quantified in GB with cost estimates. Page 3 is your Fix This First roadmap, ordered by effort vs. impact and sequenced for Nutanix Move readiness.
  • Q What happens after the report?
    The brief is the first step in a structured exit path. Once you know what you’re dealing with, the HCI Migration Advisor helps you size where you’re going using your RVTools export. From there, The Architect’s Review is a live engagement to build your full Nutanix Move migration plan, wave sequencing, and cutover runbook with your team.
