Migrate Harness pipelines from v0 to v1 simplified format via MCP tools. Converts expressions from angle-bracket to ${{ }} syntax, lowercases type names, simplifies structure, and preserves variables, failure strategies, and conditional logic. Use when asked to migrate a pipeline, convert v0 to v1, upgrade pipeline format, modernize pipeline syntax, or compare v0 vs v1. Trigger phrases: migrate pipeline, convert to v1, upgrade pipeline, v0 to v1, modernize pipeline, simplified format.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Migrate Pipeline
Convert Harness pipelines from v0 to v1 simplified format via MCP.
## Instructions
### Step 1: Fetch Current v0 Pipeline
```
Call MCP tool: harness_get
Parameters:
resource_type: "pipeline"
resource_id: "<pipeline_identifier>"
org_id: "<organization>"
project_id: "<project>"
```
### Step 2: Convert v0 to v1
Apply these transformations:
### Expression Mapping
| v0 Expression | v1 Expression |
|--------------|---------------|
| `<+pipeline.variables.x>` | `${{ pipeline.variables.x }}` |
| `<+stage.variables.x>` | `${{ stage.variables.x }}` |
| `<+steps.id.output.outputVariables.x>` | `${{ steps.id.output.x }}` |
| `<+trigger.branch>` | `${{ trigger.branch }}` |
| `<+secrets.getValue("x")>` | `${{ secrets.x }}` |
| `<+pipeline.sequenceId>` | `${{ pipeline.sequenceId }}` |
| `<+input>` | `${{ input }}` |
### Structure Changes

How to install
mdr add harness/harness-skills/migrate-pipeline@sha256:31fff63c7450f371The line at the top of this page pins the label v2.0.0, 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.
