AWS to STACKIT

This guide describes the common path from an AWS Terraform estate to a reviewable STACKIT migration package.

Assess the Terraform estate

stacktoit assess ./aws-terraform

The assessment reads the Terraform configuration and its modules, builds a dependency graph, evaluates the migration of source resources, and writes the target assessment and migration package.

Understand the mapping

Review the migration classification, the proposed target service, and whether each configuration property is retained, transformed or requires attention. A source resource may map to Terraform, an API procedure, a manual action, or a redesign decision. The report explains which path is proposed and why.

Do not interpret the presence of a Terraform draft as automatic approval to apply it.

Add an optional AWS inventory

For a comparison between Terraform and AWS inventory, use discover:

stacktoit discover commands
stacktoit discover aws ./aws-terraform-stacktoit --region eu-central-1
stacktoit assess ./aws-terraform ./aws-terraform-stacktoit

discover aws uses your local AWS CLI credentials and read-only collection commands. assess itself does not connect to an AWS account. The inventory is saved in the output’s review directory for comparison in the next assessment.

For an existing collection of AWS CLI output files, use stacktoit discover import aws-cli instead.

Review target and execution artifacts

• Open index.html and inspect architecture and decision findings.
• Review terraform/ and target-plan.json with the target platform team.
• Read execution-plan.json and execution/ for sequencing, prerequisites and operator actions.
• Confirm any design choices and regenerate the assessment with the supplied inputs.
• Run stacktoit verify before archiving or sharing a finished assessment.
