Google moved migration modelling into agentic chat. Keep the assumptions auditable.

In brief

Google Cloud announced AI-powered Quick Assessments in Migration Center on 25 August. The company says the feature can ingest infrastructure data or VMware inventory exports, produce a target bill of materials and total-cost-of-ownership estimate, map services, explain assumptions through an agentic assistant, and export an executive business case.

The announcement is useful because the migration-assessment bottleneck is often not an absence of cloud options. It is the time required to reconcile inventory, cost baselines, application dependencies, usage assumptions and financial ownership into a decision a steering group can challenge. Faster modelling can compress that work, but it cannot remove accountability for the inputs.

What the announcement changes

Google Cloud describes a workflow that combines AI-assisted quick assessment, enhanced billing-assessment capabilities, cost modelling, service mapping and downloadable reports. The feature can make an early business case more accessible to teams that would otherwise start with spreadsheets and manual discovery.

However, a TCO model is a hypothesis, not a migration decision. Its result depends on workload assumptions, utilisation, licensing, networking, resilience design, migration sequencing, target operating model and change cost. An agent that explains an assumption makes the model easier to interrogate; it does not establish that the assumption is correct for a particular organisation.

How to use it responsibly

Use AI-generated assessment output to create a transparent first pass, then subject it to a human challenge process. The review should identify source-system coverage, distinguish measured inputs from estimated inputs, test critical cost drivers, and separate infrastructure savings from the full programme cost of application remediation, data movement, security design and operating change.

The practical decision is whether the tool increases the quality and speed of an evidence pack. It should not become a mechanism for moving an unreviewed vendor model straight into an investment committee.

Questions for a migration board

1. Which inventory fields were observed, and which were inferred?
2. What assumptions drive the largest variance in the TCO result?
3. Does the proposed target architecture meet resilience, sovereignty and performance requirements?
4. Who owns the business case after the initial assessment has been exported?
