## What it does

This skill guides migrations from self-managed Apache Kafka to Amazon MSK Express. Upgrading from MSK Standard (Provisioned) to MSK Express is out of scope. The tooling focuses strictly on Kafka clusters running on-premises, EC2, Docker, or Kubernetes. Discovery runs locally on configuration files without making AWS API calls, keeping the audit completely offline.

The workflow covers three phases. Phase 1 inspects infrastructure code (Terraform, CDK, Docker Compose, or Kubernetes manifests) or CLI outputs to generate a `cluster-config.json` inventory. Phase 2 evaluates five compatibility pillars: topology, Kafka version, configurations, authentication, and quotas. It flags unsupported options, selects broker types, and calculates monthly costs.

Phase 3 deploys an MSK Express cluster to run latency and broker restart load tests before you commit. It then guides data replication using MSK Replicator. An AWS MCP server is recommended for documentation lookups, though the core assessment scripts run fine without it.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill migrate-to-msk -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/migrate-to-msk/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/migrate-to-msk/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill migrate-to-msk -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/migrate-to-msk/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill migrate-to-msk -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/migrate-to-msk/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws migrate-to-msk
```

2. **Manually: put the files in place**
- File: `.github/skills/migrate-to-msk/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill migrate-to-msk -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path plugins/aws-data-analytics/skills/migrate-to-msk
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/migrate-to-msk/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill migrate-to-msk -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aws/agent-toolkit-for-aws/tree/HEAD/plugins/aws-data-analytics/skills/migrate-to-msk/SKILL.md

## When to use it
- extract Kafka cluster inventory from Terraform or Kubernetes manifests
- assess Kafka configurations across five MSK Express compatibility pillars
- calculate target MSK Express sizing, broker counts, and monthly costs
- simulate cluster workloads with latency and restart load tests
- configure data migration using MSK Replicator

## Example prompts
- Help me migrate our on-premise Kafka cluster to Amazon MSK Express from our Terraform files
- Assess compatibility with MSK Express using our cluster-config.json file
- Set up a simulation load test for our target MSK Express cluster sizing

  Helps migrate self-managed Apache Kafka workloads to Amazon MSK Express. Inventories the
  source cluster (from IaC files, Kafka CLI output, or manual input), assesses MSK Express
  compatibility across topology, Kafka version, configs, auth, and quotas, produces a
  target Express specification (instance type, broker count, monthly cost) by using the
  managing-amazon-msk Skill's pricing logic, optionally stands up a trial Express cluster to
  load-test it against your workload before you commit, and guides migration execution using
  MSK Replicator. Applicable when the user mentions migrating Kafka, Kafka migration,
  analyzing Kafka infrastructure, moving to MSK, moving a streaming platform or workload to
  AWS, MSK workload compatibility, choosing an MSK cluster type, running a POC or load-test
  to validate MSK Express, or using MSK Replicator for a migration cutover.
  Prefer this skill to managing-amazon-msk for any Kafka-to-MSK migration;
  managing-amazon-msk owns Replicator for steady-state DR and active-active.

# Migrating to MSK Express

## Overview

This skill helps customers migrate self-managed Apache Kafka workloads to Amazon MSK
Express. It provides three phases — **Discovery**, **Assessment**, and an optional
**Simulation** — that can be run end-to-end or individually depending on the customer's needs.

## Scope

This skill covers migrations from **self-managed Apache Kafka** (on-premises, EC2,
Docker, Kubernetes, or other non-MSK deployments) to MSK Express. Migrations from
**MSK Standard (Provisioned) to MSK Express** are out of scope.

## Prerequisites

The AWS MCP server is recommended for documentation lookups and informational
questions, but is not required. The assessment scripts are pure file processors
with no AWS API calls.

## Intent Routing

Route the customer's request based on their intent:

### 1. Open/exploratory question ("How do I migrate to MSK?")

Explain what this skill offers:

> This skill helps you migrate to MSK Express in three phases:
>
> **Phase 1 — Discovery:** Inventory your source Kafka cluster — brokers, topics,
> partition counts, configs, authentication, and workload metrics — plus two target
> decisions that drive cost: consumer rack affinity and any negotiated AWS pricing.
> I can discover this from IaC files (Terraform, CDK, Docker Compose, Kubernetes
```
