VMware migration assessment — what to inspect before committing to an exit

What a structured VMware migration assessment actually inspects.

Why a structured assessment matters

VMware migration is a 6-24 month project depending on scale. Committing without structured assessment often produces:

  • TCO surprises
  • Workload-specific blockers discovered mid-project
  • Destination architecture inadequate for production
  • Failed cohort migrations and rollbacks

A 14- or 28-day assessment costs a fraction of the migration. It’s the cheapest insurance.

Four workstreams in a structured VMware assessment

1. Inventory and platform maturity

Workload classification, OS mix, criticality tiering, IaC coverage of current state.

2. Sovereignty and regulator gap (where applicable)

DORA/NIS2/sectoral compliance posture, audit-readiness gaps.

3. Cost and cloud-spend posture

Honest TCO across substrates (current VMware, target Cozystack/alternative, time-to-positive).

4. Developer self-service and platform engineering

Time-to-environment current vs. target; golden-path priorities.

What output the assessment produces

A 30-50 page written report covering all four workstreams plus three outcomes: time-to-environment, compliance-by-design map, cost trajectory.
