Assess an existing app (VMware/EC2) by source code analysis for the replatform vs rearchitect decision, and execute the approved migration onto Amazon ECS. Covers: source code analysis; language/framework detection (Java, .NET, Spring, Struts, WebSphere tWAS/Liberty); cloud/container fit scoring; strategy recommendation; tWAS containerization and Liberty migration; migration planning; AWS Transform orchestration; containerization and ECR push; Replatform (ECS on EC2, bridge, sticky sessions)…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ECS Modernize Assess an existing application (VMware / EC2) through read-only source code analysis, decide between replatform and rearchitect, and execute the approved migration onto Amazon ECS. ## Overview This skill runs a **two-phase pipeline** with an explicit control point between the phases: 1. **Assessment_Phase (strictly read-only)** — static Source_Analysis of the target source code (tech-stack detection, then Blocker detection), cloud/container fit scoring (a 0–100 Fit_Score over six weighted Scoring_Dimensions), and a migration-strategy recommendation: **Replatform** (containerize as-is onto ECS on EC2 with a static configuration) vs **Rearchitect** (modernize the app for Fargate, including ECS Express Mode, which runs on Fargate, or for Managed Instances). Both strategies are always presented with trade-offs regardless of the score. **Deliverable:** exactly one Markdown **Modernization_Report**. …

How to install
mdr add aws-samples/sample-apex-skills/ecs-modernize@sha256:839d8dc63e161a82The line at the top of this page pins the label git:20261108.ad08020, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
