Upgrading MWAA Environments

AWS MCP server (optional but recommended): running the AWS CLI commands in this skill through the AWS MCP server gives sandboxed execution and audit logging. Every command here also works with the plain AWS CLI, so the skill does not require the MCP server or any MCP-only tools.

Upgrade an MWAA provisioned environment to any newer, MWAA-supported Airflow version: within 2.x, within 3.x, or across the 2.x-to-3.x boundary. The target is a parameter. A path planner computes an ordered version-jump list from (source, target); the latest 2.11.x stepping-stone version and a Python-line transition step are inserted only when the path requires them. A deployment approach is selected by whether historical run data must be preserved and whether the same environment (its URL/ARN) must be kept: a new-environment upgrade (new-environment), a rehearsed in-place upgrade validated on a test copy first (in-place-rehearsed), or a direct in-place upgrade (in-place-direct).
