## What it does

The command moves data between GitHub and Linear. You pick the direction with an argument: `--github-to-linear`, `--linear-to-github`, `--bidirectional` or `--validate`. Work runs in stages — volume assessment, planning with rollback checkpoints, extraction, field transformation, batch writing, then an integrity check on the other side.

The toolset is plain: `Read`, `Write`, `Edit` and `Bash`. At startup it checks the environment, running `gh --version` for the GitHub CLI and looking at Linear MCP server connectivity. No GitHub CLI means the first step fails right away, so install it before you run anything. Linear needs an authenticated MCP server.

Rollback is the point. Tracker migrations break on issue relationships and field mismatches, so the command builds a phased plan with checkpoints instead of writing straight away. On a large dataset, run `--validate` first — that is the cheap way to find mapping gaps.

## Requirements
- Works with: GitHub, Linear

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command sync/sync-migration-assistant
```

2. **Manually: put the files in place**
- File: `.claude/commands/sync-migration-assistant.md` — Call it with /sync-migration-assistant. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/sync-migration-assistant.md` — Call it with /prompts:sync-migration-assistant. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/sync-migration-assistant.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/sync-migration-assistant.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/sync/sync-migration-assistant.md

## When to use it
- move issues from GitHub to Linear
- verify data integrity after a migration
- plan a tracker move with rollback checkpoints
- set up two-way sync between trackers
- check issue relationships before transferring

## Example prompts
- /sync-migration-assistant --github-to-linear
- /sync-migration-assistant --validate
- /sync-migration-assistant --bidirectional

# Sync Migration Assistant

Execute comprehensive data migration between GitHub and Linear with enterprise-grade capabilities: **$ARGUMENTS**

## Current Migration Environment

- Source system: !`gh --version 2>/dev/null && echo "GitHub CLI available" || echo "GitHub CLI needed"`
- Target system: Linear MCP server connectivity and authentication status
- Migration scope: Analysis of data volume and complexity for planning
- Infrastructure: Database, queue services, and processing capacity assessment

## Task

Implement large-scale data migration with comprehensive validation and enterprise features:

**Migration Type**: Use $ARGUMENTS to specify GitHub-to-Linear, Linear-to-GitHub, bidirectional setup, or validation mode

**Migration Framework**:
1. **Pre-Migration Assessment** - Data volume analysis, dependency mapping, risk assessment, resource planning
2. **Migration Planning** - Phased approach design, rollback strategy, validation checkpoints, timeline estimation
3. **Data Extraction** - Comprehensive data harvesting, relationship preservation, metadata capture, error handling
4. **Transformation Engine** - Field mapping, format conversion, validation rules, data enrichment
5. **Migration Execution** - Batch processing, progress tracking, error recovery, quality assurance
6. **Post-Migration Validation** - Data integrity verification, relationship validation, performance testing, rollback readiness

**Enterprise Features**: Large-scale batch processing, comprehensive error recovery, detailed audit trails, rollback capabilities, performance optimization.

**Quality Assurance**: Multi-stage validation, data integrity checks, relationship verification, comprehensive testing, enterprise monitoring.

**Output**: Complete migration system with phased execution, comprehensive validation, detailed reporting, and enterprise-grade reliability for large-scale data transitions.
