Advanced Features

Smart ID Mapping

Automatic transformation of foreign keys between OC3 and OC4:

// Example transformations
'language_id' => 'ID_MAPPING:language'
'currency_id' => 'ID_MAPPING:currency'
'customer_group_id' => 'SMART_CUSTOMER_GROUP_ID'
'store_id' => 'SMART_STORE_ID'

Smart mapping strategies:

• Direct mapping for non-zero values
• Default values for zero
• Composite key support

Bulk Processing

Performance optimization for large datasets:

Feature	Before	After	Improvement
Orders (86K)	15+ hours	4 minutes	225x faster
Products (50K)	2 hours	8 minutes	15x faster
Customers (100K)	3 hours	12 minutes	15x faster

Configuration:

'migration' => [
    'default_batch_size' => 1000,
    'memory_limit' => '512M',
]

Image Transfer

Automated image copying and validation:

• Source: OC3 image directory
• Target: OC4 image directory
• Types: Products, categories, manufacturers
• Validation: File existence, size, format
• Statistics: Transfer count, success rate

Validation Framework

Post-migration integrity checks:

Data Integrity

• Record count validation
• Foreign key integrity
• Required fields validation
• Data type validation

Business Rules

• Price consistency
• Stock validation
• Order total calculations
• Tax calculations

Image Validation

• File existence
• Path resolution
• Format validation
• Size checks
