# Post Migration Guide

This guide explains how to migrate posts between WordPress sites using the SEO automation tool.

## Overview

The migration feature allows you to move posts from one WordPress site to another while preserving:
- Post content (title, body, excerpt)
- Categories (automatically created if they don't exist)
- Tags (automatically created if they don't exist)
- SEO metadata (RankMath, Yoast SEO)
- Post slug

## Migration Modes

There are two ways to migrate posts:

### 1. CSV-Based Migration

Migrate specific posts listed in a CSV file.

**Requirements:**
- CSV file with at least two columns: `site` and `post_id`

**Usage:**
```bash
# Basic migration (posts deleted from source after migration)
./seo migrate posts_to_migrate.csv --destination mistergeek.net

# Keep posts on source site
./seo migrate posts_to_migrate.csv --destination mistergeek.net --keep-source

# Publish immediately instead of draft
./seo migrate posts_to_migrate.csv --destination mistergeek.net --post-status publish

# Custom output file for migration report
./seo migrate posts_to_migrate.csv --destination mistergeek.net --output custom_report.csv
```

### 2. Filtered Migration

Migrate posts based on filters (category, date, etc.).

**Usage:**
```bash
# Migrate all posts from source to destination
./seo migrate --source webscroll.fr --destination mistergeek.net

# Migrate posts from specific categories
./seo migrate --source webscroll.fr --destination mistergeek.net --category-filter VPN "Torrent Clients"

# Migrate posts with specific tags
./seo migrate --source webscroll.fr --destination mistergeek.net --tag-filter "guide" "tutorial"

# Migrate posts by date range
./seo migrate --source webscroll.fr --destination mistergeek.net --date-after 2024-01-01 --date-before 2024-12-31

# Limit number of posts
./seo migrate --source webscroll.fr --destination mistergeek.net --limit 10

# Combine filters
./seo migrate --source webscroll.fr --destination mistergeek.net \
  --category-filter VPN \
  --date-after 2024-01-01 \
  --limit 5 \
  --keep-source
```

## Command Options

### Required Options

- `--destination`, `--to`: Destination site (mistergeek.net, webscroll.fr, hellogeek.net)
- `--source`, `--from`: Source site (for filtered migration only)

| `--date-before` | Migrate posts before this date (YYYY-MM-DD) | No limit |
| `--limit` | Maximum number of posts to migrate | No limit |
| `--output`, `-o` | Custom output file for migration report | Auto-generated |
| `--dry-run` | Preview what would be done without doing it | Execute |

## Migration Process

### What Gets Migrated

1. **Post Content**
   - Title
   - Body content (HTML preserved)
   - Excerpt
   - Slug

2. **Categories**
   - Mapped from source to destination
   - Created automatically if they don't exist on destination
   - Hierarchical structure preserved (parent-child relationships)

3. **Tags**
   - Mapped from source to destination
   - Created automatically if they don't exist on destination

4. **SEO Metadata**
   - RankMath title and description
   - Yoast SEO title and description
   - Focus keywords

### What Doesn't Get Migrated

- Featured images (must be re-uploaded manually)
- Post author (uses destination site's default)
- Comments (not transferred)
- Custom fields (except SEO metadata)
- Post revisions

## Migration Report

After migration, a CSV report is generated in `output/` with the following information:

```csv
source_site,source_post_id,destination_site,destination_post_id,title,status,categories_migrated,tags_migrated,deleted_from_source
webscroll.fr,123,mistergeek.net,456,"VPN Guide",draft,3,5,True
```

## Examples

### Example 1: Migrate Specific Posts from CSV

1. Create a CSV file with posts to migrate:
```csv
site,post_id,title
webscroll.fr,123,VPN Guide
webscroll.fr,456,Torrent Tutorial
```

2. Run migration:
```bash
./seo migrate my_posts.csv --destination mistergeek.net
```

### Example 2: Migrate All VPN Content

```bash
./seo migrate --source webscroll.fr --destination mistergeek.net \
  --category-filter VPN "VPN Reviews" \
  --post-status draft \
  --keep-source
```

### Example 3: Migrate Recent Content

```bash
./seo migrate --source webscroll.fr --destination mistergeek.net \
  --date-after 2024-06-01 \
  --limit 20
```

### Example 4: Preview Migration

```bash
./seo migrate --source webscroll.fr --destination mistergeek.net \
  --category-filter VPN \
  --dry-run
```

## Best Practices

### Before Migration

1. **Backup both sites** - Always backup before bulk operations
2. **Test with a few posts** - Migrate 1-2 posts first to verify
3. **Check category structure** - Review destination site's categories
4. **Plan URL redirects** - If deleting from source, set up redirects

### During Migration

1. **Use dry-run first** - Preview what will be migrated
2. **Start with drafts** - Review before publishing
3. **Monitor logs** - Watch for errors or warnings
4. **Limit batch size** - Migrate in batches of 10-20 posts

### After Migration

1. **Review migrated posts** - Check formatting and categories
2. **Add featured images** - Manually upload if needed
3. **Set up redirects** - From old URLs to new URLs
4. **Update internal links** - Fix cross-site links
5. **Monitor SEO** - Track rankings after migration

## Troubleshooting

### Common Issues

**1. "Site not found" error**
- Check site name is correct (mistergeek.net, webscroll.fr, hellogeek.net)
- Verify credentials in config.yaml or .env

**2. "Category already exists" warning**
- This is normal - the migrator found a matching category
- The existing category will be used

**3. "Failed to create post" error**
- Check WordPress REST API is enabled
- Verify user has post creation permissions
- Check authentication credentials

**4. Posts missing featured images**
- Featured images are not migrated automatically
- Upload images manually to destination site
- Update featured image on migrated posts

**5. Categories not matching**
- Categories are matched by name (case-insensitive)
- "VPN" and "vpn" will match
- "VPN Guide" and "VPN" will NOT match - new category created

## API Usage

You can also use the migration feature programmatically:

```python
from seo.app import SEOApp

app = SEOApp()

# CSV-based migration
app.migrate(
    csv_file='output/posts_to_migrate.csv',
    destination_site='mistergeek.net',
    create_categories=True,
    create_tags=True,
    delete_after=False,
    status='draft'
)

# Filtered migration
app.migrate_by_filter(
    source_site='webscroll.fr',
    destination_site='mistergeek.net',
    category_filter=['VPN', 'Software'],
    date_after='2024-01-01',
    limit=10,
    create_categories=True,
    delete_after=False,
    status='draft'
)
```
