migration

A workflow for moving older Adobe Experience Manager installations—such as AEM 6.x, on-premises, or AMS—to AEM as a Cloud Service. It reviews a project for migration issues and produces a read-only migration runbook, handling one issue pattern at a time.

In plain words
What is it for?
Use it to assess an AEM project, review migration findings, identify patterns such as scheduler or replication changes, and plan the work needed for a cloud-service move.
Why use it?
It gives teams a structured way to discover cloud-service migration work instead of trying to change an entire project at once. It connects findings from Adobe assessment tools with the relevant migration guidance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/analyzer-runner.js, scripts/bpa-findings-helper.js, scripts/bpa-findings-helper.test.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 510 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AEM as a Cloud Service — Code Migration

Source → target: Legacy AEM 6.x / AMS / on-premAEM as a Cloud Service. Scoped under skills/aem/cloud-service/skills/migration/ so this is not confused with Edge Delivery or 6.5 LTS.

This skill drives the migration workflow: BPA data, CAM/MCP, one pattern per session, and target discovery. Transformation rules and steps live in the code-assessment skill — once a finding's pattern is identified, hand off to {code-assessment}/<pattern>/SKILL.md (or the relevant shared reference under {code-assessment}/references/).

Setup: Use the aem-cloud-service install (see repository root README) so both migration and code-assessment paths are available. If you already have the monorepo open with resolvable {code-assessment} paths, no separate install step is required.

Quick start (for the person driving the agent)

One pattern per chat/session — if you ask to "fix everything," the skill will ask you to pick first (e.g. scheduler vs replication vs htlLint).

You have… Say something like… What happens
A whole project to assess "Review my code for AEMaaCS migration" Generates read-only migration-runbook.mdall migration patterns (Java cascade + htlLint + osgiConfig), affected files, sample prompts. No edits.
A BPA CSV "Fix scheduler findings using ./path/to/bpa.csv" Fastest path: CSV → cached collection → files
CAM + MCP only "Get scheduler findings from CAM; I'll pick the project when you list them." Agent lists projects → you confirm → MCP fetch (cam-mcp.md)
Just a few files "Migrate scheduler in core/.../MyJob.java" Manual flow: no BPA required
OSGi → Cloud Manager "Scan my config files and create Cloud Manager environment secrets or variables." Agent auto-reads references/osgi-cfg-json-cloud-manager.md (full Adobe-aligned rules inlined there); no BPA pattern id
HTL lint warnings "Fix htlLint issues in ui.apps" Proactive discovery via rg → fix per the HTL lint reference
Template modernization "Migrate my static templates to editable templates and generate Modernize Tools rules." / "Create editable templates from my static templates." / "Generate AEM Modernize Tools structure/component/policy rules." Agent auto-reads references/template-modernization/template-modernization-context.md (shared discovery + structured context), produces a per-template plan table, then executes the plan using editable-template-creation.md and aem-modernization.md, and validates via template-modernization-validation.md. No BPA pattern id.
Dialog migration "Convert my Classic UI / ExtJS dialogs to Touch UI." / "Upgrade Coral 2 dialogs to Coral 3." / "Fix LUI dialog findings." Agent reads references/legacy-ui/dialog/context.md — filters BPA LUI to dialog sub-types, converts via extjs-to-coral3.md or coral2-to-coral3.md, validates via validation.md. BPA pattern id: lui.
Custom widget migration "Fix my CDW findings." / "Migrate custom ExtJS widgets to Coral 3." Agent reads references/legacy-ui/cdw/context.md — inventories xtypes, maps or scaffolds Granite UI components via conversion.md, validates via validation.md. BPA pattern id: cdw. Run CDW before dialog migration when both are needed.

What ships with it

30 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

migration is a skill published in the GitHub repository adobe/skills (175 stars, last pushed 3d ago), licensed Apache-2.0. It adds 219 tokens to every session and 10,162 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
