Magento 1 to Magento 2 Migration Process

Step 1: Create a Migration Strategy

Prepare a migration roadmap that includes:

A proper migration plan minimizes downtime and business disruption.

Step 2: Set Up Magento 2 Environment

Install a fresh Magento 2 instance with:

Latest supported Magento version

Elasticsearch or OpenSearch
Redis cache

Ensure server requirements meet Magento recommendations.

Step 3: Theme Migration

Magento 1 themes are not compatible with Magento 2.

You must:

Rebuild the theme
Purchase a Magento 2-compatible theme

Implement Hyvä Theme for better performance

Many businesses use this opportunity to redesign their storefront.

Step 4: Extension Migration

Magento 1 extensions cannot be directly migrated.

For each extension:

Check Magento 2 availability.
Install Magento 2 equivalent.
Reconfigure settings.
Validate functionality.

Remove outdated or unused extensions during migration.

Step 5: Data Migration

Magento provides the Data Migration Tool for transferring data.

Migration typically includes:

Settings Migration

Transfers:

Store configurations
Tax settings
Shipping settings
Payment configurations

Data Migration

Transfers:

Products
Categories
Customers
Orders
Reviews
CMS content

Transfers newly created data before go-live to keep systems synchronized.

Step 6: Custom Module Redevelopment

Magento 1 modules require redevelopment.

Review each custom module and:

Rebuild using Magento 2 architecture
Implement Dependency Injection
Use Service Contracts
Follow Magento coding standards

This is often the most time-consuming phase.

Step 7: Integration Migration

Verify all integrations including:

ERP systems

Update API connections where necessary.

Step 8: SEO Preservation

Maintaining SEO rankings is critical.

Recommended actions:

Step 10: Go Live

Before launch:

Monitor store performance closely after launch.
