AWS Transform now handles existing AWS Control Tower landing zones and those built with AWS Organizations. It runs a gap analysis against best practices and expands the landing zone on top of current accounts, so migration can begin earlier. The service also adds an Infrastructure as Code‑only mode, outputting CDK, Terraform or Landing Zone Accelerator templates, and can connect via a delegated administrator account instead of direct access.

## The facts

- Announcement date: 2026‑10‑20 ("Tue Oct 20 2026 10:00:00 GMT+0200")
- Supports Control Tower, AWS Organizations and IaC‑only mode (CDK, Terraform, LZA)

## Why it matters

Organizations can migrate faster without giving AWS Transform full control of their accounts.
