+# Webflow to Payload CMS Migration Script
+
+Story 1.3: Content Migration Script
+
+## Overview
+
+This script migrates content from Webflow CMS to Payload CMS. It supports:
+- **JSON export** - If you have Webflow JSON export files
+- **HTML parsing** - If you only have access to the public website HTML
+- **Manual entry** - You can manually edit the JSON data file
+
+## Prerequisites
+
+1. **MongoDB must be running** - The script connects to Payload CMS which requires MongoDB
+2. **Environment variables** - Ensure `.env` file has PAYLOAD_SECRET and DATABASE_URI
+3. **Source data** - Prepare your webflow-export.json file
+
+## Quick Start
+
+```bash
+# Navigate to backend directory
+cd apps/backend
+
+# Ensure MongoDB is running (if using local)
+# Or the Payload CMS dev server:
+pnpm dev
+
+# In another terminal, run dry-run (preview mode, no changes)
+pnpm migrate:dry
+
+# Run actual migration
+pnpm migrate
+
+# Migrate specific collection
+pnpm migrate:posts
+
+# Show help
+tsx scripts/migration/migrate.ts --help
+```
+
+## Environment Setup
+
+The script loads environment variables from:
+- `.env` (project root)
+- `.env.enchun-cms-v2` (project root)
+- `apps/backend/.env`
+
+Required variables:
+```bash
+PAYLOAD_SECRET=your-secret-key
+DATABASE_URI=mongodb://localhost:27017/your-db
+R2_ACCOUNT_ID=your-r2-account
+R2_ACCESS_KEY_ID=your-access-key
+R2_SECRET_ACCESS_KEY=your-secret-key
+R2_BUCKET=your-bucket-name
+```
+
+## CLI Options
+
+| Option | Short | Description |
+|--------|-------|-------------|
+| `--dry-run` | `-n` | Run without making changes (preview mode) |
+| `--verbose` | `-v` | Show detailed logging output |
+| `--force` | `-f` | Overwrite existing items (skip deduplication) |
+| `--collection <name>` | `-c` | Specific collection: categories|posts|portfolio|all |
+| `--source <path>` | `-s` | Path to export file (default: ./data/webflow-export.json) |
+| `--batch-size <num>` | | Batch size for parallel processing (default: 5) |
+| `--help` | `-h` | Show help message |
+
+## Data Format
+
+Create a `webflow-export.json` file in the `apps/backend/data/` directory:
+
+```json
+{
+  "categories": [
+    {
+      "name": "分類名稱（中文）",
+      "slug": "category-slug",
+      "colorHex": "#0066cc"
+    }
+  ],
+  "posts": [
+    {
+      "title": "文章標題",
+      "slug": "post-slug",
+      "content": "<p>HTML content...</p>",

+## Migration Order
+
+1. **Categories** (first - no dependencies)
+2. **Media** images (independent)
+3. **Posts** (depends on Categories and Media)
+4. **Portfolio** (depends on Media)
+
+## Reports
+
+After each migration, a report is generated in `apps/backend/reports/`:
+- `migration-YYYY-MM-DD.json` - Machine-readable JSON
+- `migration-YYYY-MM-DD.md` - Human-readable Markdown
+
+## Troubleshooting
+
+### Script fails to connect to Payload CMS
+Ensure the Payload CMS server is running:
+```bash
+cd apps/backend
+pnpm dev
+```
+
+### Images not uploading
+Check environment variables in `.env`:
+- `R2_ACCOUNT_ID`
+- `R2_ACCESS_KEY_ID`
+- `R2_SECRET_ACCESS_KEY`
+- `R2_BUCKET_NAME`
+
+### Duplicate entries
+By default, the script skips existing items. Use `--force` to overwrite:
+```bash
+pnpm migrate --force
+```
