AWS Transform assessment
AWS's own migration assessment. Ingests inventory you already hold and returns a business case, with no appliance to deploy.
What it is
A first-party AWS capability that turns an existing server inventory into a costed migration business case. It produces EC2 right-sizing from your current specs, EBS and FSx recommendations, side-by-side TCO scenarios, and a business value assessment. AWS states there is no additional charge for it.
How we use it
We use it for speed, usually to get a directional figure in front of a stakeholder quickly, then rebuild the licensing layer separately before anything is treated as a recommendation.
One thing to watch: it is only as good as what you feed it. Utilisation quality, dependency data and licensing edition detail all come from the source rather than from Transform, so a thin inventory produces a confident-looking model built on very little, and the entitlement analysis still has to happen elsewhere.
Official resources
We would rather point you at the vendor than paraphrase them. What we add is what happens when you run it against a real estate.
