## What it does

This skill rewrites classic Dynatrace DQL queries into their Smartscape counterparts. It splits queries into three core patterns: mass data filtering with entity conditions, mass data queries using entity subqueries, and direct entity listings. For logs or metrics queries, the workflow resolves filters against raw dimensions first, using Smartscape only as a fallback.

It handles mappings for common entities such as hosts, services, and Kubernetes resources. The skill maps legacy functions like `entityName` and `entityAttr` to `getNodeName` or direct fields, and converts relationship lookups like `belongs_to` or `runs` into `traverse` calls. Special cases, like host groups lacking direct standalone nodes, map directly to attributes on the host entity.

Asset-level migration workflows fall outside this skill. You need to load the companion `dt-dql-essentials` skill beforehand to ensure rewritten queries conform to active DQL syntax standards.

## Requirements
- Works with: Dynatrace

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-migration -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-migration -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-migration -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Dynatrace/dynatrace-for-ai dt-migration
```

2. **Manually: put the files in place**
- File: `.github/skills/dt-migration/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-migration -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Dynatrace/dynatrace-for-ai --path skills/dt-migration
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-migration -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/Dynatrace/dynatrace-for-ai/tree/HEAD/skills/dt-migration/SKILL.md

## When to use it
- migrate standalone `fetch dt.entity.*` queries to `smartscapeNodes`
- replace inline `classicEntitySelector` clauses with raw dimension filters
- rewrite classic relationship paths like `belongs_to` into `traverse`
- update legacy functions such as `entityName` and `entityAttr`

## Example prompts
- Migrate this `fetch dt.entity.host` query to `smartscapeNodes`.
- Rewrite the `classicEntitySelector` filter in this metric query using raw dimensions.
- Update legacy `runs[...]` relationships and `entityName` calls to Smartscape syntax.

description: Migrate Dynatrace classic and Gen2 entity-based DQL to Smartscape equivalents. Covers three scenarios. (1) mass data queries filtered by classic entity conditions — migrate to direct dimension filters first, Smartscape only as fallback; (2) mass data queries using entity subqueries for filtering — same dimension-first strategy; (3) pure entity list queries — migrate fetch dt.entity.* to smartscapeNodes. Also handles entityName, entityAttr, classicEntitySelector, and classic relationship patterns.

# Smartscape Migration Skill

This skill migrates Dynatrace classic and Gen2 entity-based DQL queries and query patterns to Smartscape-based equivalents.

Load the **dt-dql-essentials** skill before writing final DQL so the translated query also follows current DQL syntax rules.

This skill focuses on Smartscape-oriented DQL migration only. It does not cover asset-level migration workflows.

## Query Purpose Classification

**Start here.** The correct migration strategy depends on what the query is actually trying to do — not just which classic constructs it uses.

There are three distinct situations:

| # | Situation | Classic anti-pattern | Migration strategy |
| --- | --- | --- | --- |
| 1 | Mass data query filtered by entity conditions | `classicEntitySelector(...)` inline in `filter:` of a timeseries, logs, or metrics query | Resolve entity conditions to raw data dimensions first. Smartscape is a fallback, not the default. |
| 2 | Mass data query using entity subquery for filtering | `fetch dt.entity.*` inside `in [...]`, `lookup [...]`, or `join [...]` to filter the outer mass data query | Same dimension-first strategy. Rewrite as raw dimension filter or `in [smartscapeNodes ...]` subquery. |
| 3 | Pure entity list query | `fetch dt.entity.*` used standalone or as the primary result source | `smartscapeNodes` is the only valid path. No raw dimension alternative exists. |

**Decision:**

- **Situations 1 or 2** — load [references/mass-data-filtering-strategy.md](references/mass-data-filtering-strategy.md) and complete **all steps** including field discovery (Step 2) and equivalence verification (Step 4). Do not skip the `fieldsSnapshot` gates — they determine which approach is viable. Only fall back to the Migration Workflow below when the entity-type mapping or relationship traversal is needed to complete a Smartscape subquery.
- **Situation 3** — continue with the Migration Workflow and entity mapping table below.
