# WPML Migration Guide

> **Critical Document**: Complete guide for migrating enterprise WordPress sites from WPML to Multilingual Press Zone.

---

## Overview

### Migration Goals

1. **Zero Data Loss**: All translations preserved
2. **Minimal Downtime**: < 1 hour for 500K+ posts
3. **Reversible**: Rollback capability if issues occur
4. **Performance Verification**: Measure speed improvements

### Target Audience

- Enterprise site administrators with 50K+ posts
- Agencies managing multiple WPML sites
- E-commerce sites with WooCommerce + WPML

---

## Pre-Migration Checklist

### System Requirements

**Before starting migration, verify**:

- [ ] **WordPress Version**: 6.0 or higher
- [ ] **PHP Version**: 8.1 or higher (8.3 recommended)
- [ ] **MySQL Version**: 8.0 or higher (or MariaDB 10.6+)
- [ ] **Available Disk Space**: 2x current database size
- [ ] **Memory Limit**: 512MB or higher (`memory_limit = 512M` in php.ini)
- [ ] **Max Execution Time**: 300 seconds or higher (`max_execution_time = 300`)
- [ ] **WP-CLI Installed**: For command-line migration (optional but recommended)

### WPML Configuration Audit

**Document current WPML setup**:

- [ ] Number of languages configured
- [ ] Default language
- [ ] URL structure (directories, parameters, or domains)
- [ ] Number of posts to migrate
- [ ] Number of pages to migrate
- [ ] Number of custom post types
- [ ] Number of taxonomies (categories, tags)
- [ ] Number of string translations
- [ ] Active WPML addons (WooCommerce, ACF, etc.)

**Run this query to get counts**:

```sql
-- Count translated posts
SELECT COUNT(*) FROM wp_icl_translations WHERE element_type LIKE 'post_%';

-- Count string translations
SELECT COUNT(*) FROM wp_icl_strings;

-- Count languages
SELECT COUNT(*) FROM wp_icl_languages WHERE active = 1;
```

### Backup Strategy

**CRITICAL: Create complete backup before migration**

**Backup Checklist**:

- [ ] **Database Backup**: Full SQL dump via phpMyAdmin, Adminer, or CLI
  ```bash
  wp db export wpml-backup-$(date +%Y%m%d-%H%M%S).sql
  ```

- [ ] **Files Backup**: wp-content/uploads, wp-content/plugins, wp-content/themes
  ```bash
  tar -czf wpml-files-backup-$(date +%Y%m%d-%H%M%S).tar.gz wp-content/
  ```

- [ ] **WPML Settings Export**: Export WPML configuration XML
  - WPML → Support → Troubleshooting → Export/Import

- [ ] **Test Restore**: Verify backup integrity by restoring to staging

**Backup Retention**:
- Keep backups for at least 30 days post-migration
- Store backups off-server (S3, Dropbox, external drive)

## Data Mapping: WPML → MPZ

### Database Tables

| WPML Table | MPZ Equivalent | Mapping Notes |
|------------|----------------|---------------|
| `wp_icl_languages` | `wp_mpz_languages` | language_code → code, default_locale → locale |
| `wp_icl_translations` | `wp_mpz_translations` | element_id → element_id, language_code → language_code |
| `wp_icl_strings` | `wp_mpz_string_translations` | name → context, value → original_string |
| `wp_icl_string_translations` | `wp_mpz_string_translations` | value → translated_string |

### Language Codes

**WPML uses 2-letter codes, MPZ uses full locale codes**:

| WPML Code | MPZ Locale | Language Name |
|-----------|-----------|---------------|
| `en` | `en_US` | English (US) |
| `es` | `es_ES` | Spanish (Spain) |
| `fr` | `fr_FR` | French (France) |
| `de` | `de_DE` | German (Germany) |
| `pt` | `pt_BR` | Portuguese (Brazil) |
| `ar` | `ar` | Arabic |
| `zh` | `zh_CN` | Chinese (Simplified) |

**Migration Script handles automatic mapping**

### URL Structure

**WPML URL Formats**:
1. **Directories**: `/en/page`, `/es/page`
2. **Parameters**: `/?lang=en`
3. **Domains**: `en.example.com`, `es.example.com`

**MPZ URL Formats**:
1. **Directories** (default): `/en-us/page`, `/es-es/page`
2. **Subdomains** (optional): `en.example.com`, `es.example.com`
3. **Parameters** (fallback): `/?lang=en-us`

**Migration Wizard preserves URL structure** and sets up redirects.

### Translation Relationships

**WPML uses `trid` (translation group ID)**:

```sql
-- WPML structure
wp_icl_translations:
  - translation_id (PK)
  - element_id (post_id)
  - trid (translation group)
  - language_code
  - source_language_code
```

**MPZ uses `translation_group_id`**:

```sql
-- MPZ structure
wp_mpz_translations:
  - id (PK)
  - element_id (post_id)
  - translation_group_id (same as WPML trid)
  - language_code
  - source_language_code
```

**Direct 1:1 mapping, preserves translation relationships**

## Migration Methods

### Method 1: Migration Wizard (Recommended)

**Best for**: Most users, especially non-technical administrators

**Process**:
1. Install MPZ plugin (keep WPML active)
2. Navigate to WordPress Admin → Multilingual → Tools → WPML Migration
3. Click "Start Migration Wizard"
4. Follow 5-step wizard
5. Deactivate WPML after verification

**Advantages**:
- User-friendly UI
- Progress tracking
- Automatic error handling
- Rollback capability

**Limitations**:
- Requires browser to stay open (for large sites, use WP-CLI)
- Max 100K posts per session (use chunked mode)

### Method 2: WP-CLI (For Large Sites)

**Best for**: Sites with 100K+ posts, technical users

**Prerequisites**:
```bash
# Verify WP-CLI installed
wp --version

# Verify MPZ CLI commands available
wp mpz --help
```

**Command**:
```bash
wp mpz migrate-from-wpml --batch-size=1000 --dry-run
```

**Advantages**:
- No browser timeout issues
- Runs in background
- Detailed logs
- Resumable if interrupted

**Limitations**:
- Requires SSH access
- Command-line knowledge required

### Method 3: Manual SQL (Advanced)

**Best for**: Custom migrations, specialized requirements

**Process**:
1. Export WPML data to JSON
2. Transform data with custom script
3. Import to MPZ tables via SQL

**Advantages**:
- Full control over migration
- Can modify data during migration
- Fastest for very large datasets

**Limitations**:
- Requires database expertise
- No built-in error handling
- Manual verification required

## Migration Wizard: Step-by-Step

### Step 1: Pre-Migration Check

**Wizard performs automatic checks**:

- ✅ WPML installed and active
- ✅ WPML version compatible (3.0+)
- ✅ MPZ not already configured
- ✅ PHP memory limit sufficient
- ✅ Database disk space available
- ✅ No pending WPML background jobs

**If checks fail**:
- Wizard shows error message with resolution steps
- Example: "PHP memory limit too low (128MB). Increase to 512MB in php.ini"

### Step 2: Language Mapping

**Wizard shows WPML languages and suggests MPZ equivalents**:

| WPML Code | WPML Name | MPZ Locale | MPZ Name | Auto-Mapped |
|-----------|-----------|-----------|----------|-------------|
| `en` | English | `en_US` | English (US) | ✅ |
| `es` | Spanish | `es_ES` | Spanish (Spain) | ✅ |
| `fr` | French | `fr_FR` | French (France) | ✅ |

**User can override mappings**:
- Dropdown to select different locale (e.g., `es_MX` instead of `es_ES`)
- Preview URL structure change
- Set default language

**Content Types**:
- [ ] Posts
- [ ] Pages
- [ ] Custom Post Types (WooCommerce Products, Events, etc.)
- [ ] Taxonomies (Categories, Tags)
- [ ] String Translations
- [ ] Media (featured images, attachments)

**Advanced Options**:
- [ ] Create 301 redirects for changed URLs
- [ ] Preserve WPML tables (don't delete)
- [ ] Skip translated content already in MPZ
- [ ] Email notification when complete

To perform actual migration, remove --dry-run flag.
```

### Full Migration

```bash
wp mpz migrate-from-wpml \
  --batch-size=1000 \
  --email=admin@example.com \
  --create-redirects \
  --preserve-wpml-tables \
  2>&1 | tee migration-$(date +%Y%m%d-%H%M%S).log
```

**Flags**:
- `--batch-size=N`: Posts per batch (default: 1000)
- `--email=EMAIL`: Send completion email
- `--create-redirects`: Create 301 redirects for URL changes
- `--preserve-wpml-tables`: Don't delete WPML tables
- `--skip-content-type=TYPE`: Skip specific post types
- `--only-content-type=TYPE`: Migrate only specific post types
- `--verbose`: Detailed logging

### Resume Interrupted Migration

**If migration stops (server crash, timeout)**:

```bash
# Check migration status
wp mpz migration status

# Output:
# Migration in progress: 65% (81,230/125,432)
# Last batch: 81 completed successfully
# Next batch: 82 (posts 81,001-82,000)

# Resume migration
wp mpz migrate-from-wpml --resume
```

---

## Post-Migration Tasks

### 1. Deactivate WPML

**CRITICAL: Do NOT uninstall WPML yet (in case rollback needed)**

```
WordPress Admin → Plugins → WPML Multilingual CMS → Deactivate
```

**Keep WPML deactivated for 7-14 days** to ensure MPZ works correctly.

### 2. Performance Benchmark

**Run benchmark to verify performance improvements**:

**Using Browser DevTools**:
1. Open Chrome DevTools (F12)
2. Navigate to "Network" tab
3. Visit homepage in default language
4. Note "Load" time (e.g., 120ms)
5. Repeat for 5 different pages
6. Calculate average

**Using WP-CLI**:
```bash
wp mpz benchmark --pages=10 --languages=all
```

**Output**:
```
Running performance benchmark...

Page Load Times (average over 10 pages):
• English (en_US): 115ms
• Spanish (es_ES): 122ms
• French (fr_FR): 118ms

Average: 118ms
WPML Baseline (from logs): 2,350ms
Improvement: 19.9x faster ✅

Database Queries per Page:
• English: 3 queries
• Spanish: 4 queries
• French: 3 queries

Average: 3.3 queries
WPML Baseline: 87 queries
Improvement: 26.4x fewer queries ✅
```

### 3. Configure Cache

**Redis Setup** (recommended for enterprise sites):

```bash
# Install Redis PHP extension
sudo apt install php-redis

# Configure WordPress object cache
wp plugin install redis-cache --activate
wp redis enable
```

**Full-Page Cache**:
- WP Rocket: Enable multilingual support
- LiteSpeed Cache: Configure language-specific cache
- Cloudflare: Add language-specific cache rules

### 4. Update SEO Settings

**Yoast SEO**:
- Check sitemap includes all languages
- Verify hreflang tags correct

**Rank Math**:
- Configure multilingual sitemap
- Test hreflang implementation

**Manual Check**:
```html
<!-- Verify in page source -->
<link rel="alternate" hreflang="en-us" href="https://example.com/en-us/page" />
<link rel="alternate" hreflang="es-es" href="https://example.com/es-es/page" />
<link rel="alternate" hreflang="fr-fr" href="https://example.com/fr-fr/page" />
```

### 5. Test Integrations

**WooCommerce**:
- [ ] Product translations display correctly
- [ ] Cart works in all languages
- [ ] Checkout flow in correct language
- [ ] Email notifications in correct language

**Advanced Custom Fields (ACF)**:
- [ ] Field groups translated
- [ ] Field values preserved
- [ ] Repeater fields work

**Page Builders** (Elementor, Divi, etc.):
- [ ] Page layouts preserved
- [ ] Widgets translated
- [ ] Dynamic content in correct language

---

## Rollback Procedure

**If migration fails or critical issues arise**:

### Option 1: Reactivate WPML (Quick Rollback)

```
WordPress Admin → Plugins → WPML → Activate
WordPress Admin → Plugins → Multilingual Press Zone → Deactivate
```

**Result**: Site reverts to WPML immediately. MPZ data remains in database (no data loss).

### Option 2: Restore from Backup (Full Rollback)

**If database corrupted or severe issues**:

```bash
# Stop web server
sudo systemctl stop nginx

# Restore database
wp db import wpml-backup-20260125-120000.sql

# Restore files
tar -xzf wpml-files-backup-20260125-120000.tar.gz -C /var/www/html/

# Start web server
sudo systemctl start nginx

# Verify site works
curl -I https://example.com
```

### Option 3: Partial Rollback (Keep Some MPZ Data)

**Use if some content migrated successfully**:

```sql
-- Delete only problematic translations
DELETE FROM wp_mpz_translations WHERE element_type = 'post_product';

-- Reactivate WPML
-- Re-run migration for specific content type only
```

---

## Troubleshooting

### Common Issues

#### Issue 1: Migration Stalls at X%

**Symptoms**: Progress bar stops, no errors shown

**Causes**:
- PHP timeout
- Memory limit exceeded
- Database deadlock

**Solutions**:
```bash
# Increase PHP limits in php.ini
max_execution_time = 600
memory_limit = 1024M

# Resume migration
wp mpz migrate-from-wpml --resume

# Or reduce batch size
wp mpz migrate-from-wpml --batch-size=100 --resume
```

#### Issue 2: Translation Relationships Lost

**Symptoms**: Posts not linked to translations

**Cause**: `trid` (translation group ID) not preserved

**Solution**:
```bash
# Rebuild translation relationships
wp mpz rebuild-relationships --dry-run
wp mpz rebuild-relationships
```

#### Issue 3: URLs Not Redirecting

**Symptoms**: 404 errors on old WPML URLs

**Cause**: Redirects not created

**Solution**:
```bash
# Create redirects manually
wp mpz create-redirects --from-wpml

# Or use Redirection plugin
wp plugin install redirection --activate
# Import redirects from MPZ export
```

#### Issue 4: String Translations Missing

**Symptoms**: Theme/plugin strings not translated

**Cause**: String context mismatch

**Solution**:
```
WordPress Admin → Multilingual → String Translation
→ Re-scan strings
→ Re-import from WPML backup
```

#### Issue 5: Performance Not Improved

**Symptoms**: Page load times similar to WPML

**Causes**:
- Cache not configured
- Query optimizer not active
- Database not indexed

**Solutions**:
```bash
# Rebuild indexes
wp mpz rebuild-indexes

# Enable Redis cache
wp redis enable

# Run performance audit
wp mpz performance-audit

## Data Verification Queries

**Run these queries to verify migration success**:

### Check Language Count

```sql
-- WPML
SELECT COUNT(*) as wpml_languages FROM wp_icl_languages WHERE active = 1;

-- MPZ
SELECT COUNT(*) as mpz_languages FROM wp_mpz_languages WHERE status = 'active';
```

**Expected**: Same count

### Check Post Translation Count

```sql
-- WPML
SELECT COUNT(*) as wpml_translations 
FROM wp_icl_translations 
WHERE element_type LIKE 'post_%';

-- MPZ
SELECT COUNT(*) as mpz_translations 
FROM wp_mpz_translations 
WHERE element_type LIKE 'post_%';
```

**Expected**: Same count (or within 1-2% due to orphaned WPML entries)

### Check String Translation Count

```sql
-- WPML
SELECT COUNT(*) as wpml_strings FROM wp_icl_string_translations;

-- MPZ
SELECT COUNT(*) as mpz_strings FROM wp_mpz_string_translations;
```

**Expected**: Same count

### Find Untranslated Posts

```sql
-- Posts in default language without translations
SELECT p.ID, p.post_title, t.language_code
FROM wp_posts p
JOIN wp_mpz_translations t ON p.ID = t.element_id
WHERE t.language_code = 'en_US'
AND t.translation_group_id NOT IN (
    SELECT translation_group_id 
    FROM wp_mpz_translations 
    WHERE language_code != 'en_US'
)
AND p.post_status = 'publish'
LIMIT 10;
```
