WordPress Data Migration
========================

[](#wordpress-data-migration)

WP-CLI command that generates WXR files for WordPress Custom Post Types with meta filtering. Outputs WXR format compatible with WordPress import.

Installation
------------

[](#installation)

```
composer require achttienvijftien/wp-data-migration
```

Usage
-----

[](#usage)

### Export

[](#export)

Export posts with optional meta filtering:

```
wp data-migration export --post_type= [options]
```

**Required argument:**

- `--post_type=` - Post type to export (required)

**Supported WordPress query arguments:**

- `--post_status=` - Filter by post status (publish, draft, etc.)
- `--author=` - Filter by author ID
- `--post__in=` - Comma-separated post IDs to include
- `--posts_per_page=` - Number of posts to export (-1 for all)
- `--orderby=` - Order posts by field (date, title, etc.)
- `--order=` - Sort order (ASC or DESC)

**Custom meta filtering:**

- `--include-meta=` - Comma-separated meta keys to include
- `--exclude-meta=` - Comma-separated meta keys to exclude

**File splitting:**

- `--max_file_size=` - Maximum file size in MB before splitting (default: 15)
- `--output=` - Custom output filename or base name for split files

**Examples:**

```
# Export all products
wp data-migration export --post_type=product

# Export products with only specific meta
wp data-migration export --post_type=product --include-meta=price,sku,stock

# Export products excluding specific meta
wp data-migration export --post_type=product --exclude-meta=internal_id,temp_data

# Combine with query arguments
wp data-migration export --post_type=product --post_status=publish --include-meta=price,sku

# Export with automatic file splitting (15 MB files)
wp data-migration export --post_type=product --max_file_size=15

# Export with custom max file size (10 MB files)
wp data-migration export --post_type=product --max_file_size=10

# Export with custom base name and file splitting
wp data-migration export --post_type=product --output=products --max_file_size=20
# Creates: products-001.xml, products-002.xml, products-003.xml, etc.
```

**Default Meta Exclusions:**

The following WordPress internal meta keys are excluded by default:

- `_edit_lock`, `_edit_last` (editing locks)
- `_wp_old_slug`, `_wp_old_date` (revision data)
- Keys starting with `_oembed_` (cached embeds)

### Import

[](#import)

Use WordPress core import command:

```
# Install WordPress importer if needed
wp plugin install wordpress-importer --activate

# Import the WXR file
wp import  --authors=create
```

Export Format
-------------

[](#export-format)

Generates WXR (WordPress eXtended RSS) format containing:

- Post data (title, content, excerpt, etc.)
- Post meta (with filtering applied)
- No authors or terms (posts only)

Compatible with:

- WordPress built-in importer
- `wp import` command
- Third-party WordPress import tools

### File Splitting

[](#file-splitting)

For large exports, the plugin automatically splits the export into multiple WXR files when using the `--max_file_size`option:

- Each file is a valid, standalone WXR document with proper headers and footers
- Files are named sequentially: `export-001.xml`, `export-002.xml`, `export-003.xml`, etc.
- Custom base names are supported: `products-001.xml`, `products-002.xml`, etc.
- Splitting occurs when the file approaches the specified size limit
- Each split file can be imported independently or in sequence
- Memory-efficient streaming ensures large datasets (600k+ posts) don't cause memory issues
