Your first assessment

Before you run

Choose a Terraform or OpenTofu root module, not an arbitrary subdirectory of a larger configuration. Keep its .terraform.lock.hcl and relevant variable files available where possible. For RVTools, use the export file or CSV directory as the source.

Run an assessment

stacktoit assess ./infrastructure

The command’s console summary identifies the assessed source, completion status, migration decisions and the report’s location. For a more detailed engineering console:

stacktoit assess ./infrastructure --verbose

To run without network access:

stacktoit assess ./infrastructure --offline

Offline mode uses only source files and locally available dependencies. Missing information is identified in the resulting report rather than silently assumed.

Read the outcome in order

1. Summary: inspect the source completeness and overall migration requirements.
2. Resource findings: review treatment, target mapping and relevant differences.
3. Decisions: identify choices that require confirmation or design input.
4. Target design: inspect the Terraform draft and any target assumptions.
5. Execution plan: review sequencing, manual actions, verification and rollback conditions.

A generated execution package is not an approved change request. Keep normal architecture review and change-control procedures in place.

Continue the assessment

A run provides answer templates for design inputs and decisions. Maintain your completed answers outside the generated report directory and supply them in a subsequent assessment as applicable:

stacktoit assess ./infrastructure --inputs ./my-inputs.yaml

For architectural decisions, consult Review migration decisions.
