#1 Theme Compatibility Issue

One of the first roadblocks in Magento 2 migration is theme compatibility. Magento 1 themes do not work on Magento 2 due to significant underlying changes in the architecture.


  • Use Pre-made Magento 2 Themes: One of the simplest solutions is to purchase a pre-made Magento 2 theme. These themes are specifically designed for Magento 2 and ensure full compatibility and responsiveness.
  • Recreate Magento 1 Design for Magento 2: If you want to retain the look and feel of your Magento 1 site, consider recreating the design in Magento 2. This involves translating the design elements and structure to fit the new platform.
  • Develop a Custom Magento 2 Theme: For a unique and tailored user experience, develop a custom Magento 2 theme. This approach requires a skilled development team but provides the flexibility to design a site that meets specific business needs.

#2 Extension Compatibility Issue

Another big compatibility issue is that most Magento 1 extensions do not work on Magento 2. This can disrupt key functionality, such as eCommerce payment gateways, shipping, marketing tools, etc.


  • Utilize Built-in Magento 2 Features: Magento 2 includes many features that previously required extensions in Magento 1. Review these built-in capabilities to reduce dependency on third-party extensions.
  • Find and Purchase Compatible Magento 2 Extensions: Search for Magento 2 equivalents of the Magento 1 extensions you currently use. Magento’s marketplace offers a wide range of extensions designed for Magento 2.
  • Develop Custom Magento 2 Extensions: If necessary extensions are not available, consider developing custom Magento 2 extensions. This ensures functionality specific to your business requirements.

#3 Website Performance Issue

Since Magento 2 involves moving to a completely new platform, it can create performance problems during and after migration.


  • Hire Experienced Magento 2 Migration Developers: Experienced developers can identify potential performance bottlenecks and optimize the migration process. They can also implement best practices to Magento 2 website speed optimization post-migration.
  • Perform Migration During the Off-Season: Migrating your Magento 2 platform during the off-season is a strategic decision to minimize performance issues and potential disruptions to your business operations. The off-season is typically a period of lower traffic and sales activity, making it an ideal time to undertake significant changes.

#4 Timeline and Project Management Issue

Magento 2 migrations often take more time than initially estimated. Reasons include:

  • Customization and compatibility challenges are only discovered during migration.
  • Testing and troubleshooting post-migration issues.
  • Unexpected delays in sourcing new extensions or solutions.


  • Involve Experienced Magento 2 Migration Developers: A skilled team can manage the migration process efficiently and ensure that timelines are met.
  • Clearly Define Requirements and Project Timeline: Establish clear project requirements and a realistic timeline. This includes setting milestones and regularly reviewing progress to stay on track.

#5 Data Loss Issue

Data loss is a grave risk during any migration. With Magento 2, this can happen due to:

  • Faulty or incomplete data migration scripts.
  • Downtime and interruptions in the migration process.
  • Issues mapping data from Magento 1 to 2 due to structural differences.


  • Perform a Complete Backup of Magento 1 Data: Before starting the migration, ensure a full backup of all data from your Magento 1 site. This provides a safety net in case of any issues during the migration.
  • Filter and Selectively Migrate Essential Data: Not all data needs to be migrated. Identify and migrate essential data to streamline the process and reduce the risk of data loss.

#6 Hidden Costs

The initial quote for Magento 2 migration may not reflect all costs that could arise. Beware of:

  • Extensions requiring paid upgrades for Magento 2 compatibility.
  • Increased hosting fees for improved Magento 2 infrastructure.
  • Extra costs for unforeseen customization, troubleshooting or fixes.
  • Ongoing maintenance and license fees for new extensions or software.


  • Discuss All Initial Charges with the Migration Service Provider: Discuss all potential costs with your service provider, including setup fees, extension costs, and any other related expenses.
  • Clarify the Process for Handling Unexpected Costs: Establish a clear process for managing unexpected costs that may arise during migration. This can include setting aside a contingency budget.

#7 SEO Impact

SEO can be disrupted during Magento 2 migration due to:

  • Changes in URL structure affect search rankings.
  • Loss of site indexing during migration downtime.
  • The new site content has not yet been fully optimized for SEO.


  • Implement Proper URL Redirects: Ensure all existing URLs are properly redirected to the new Magento 2 URLs. This helps maintain search engine rankings and avoid broken links.
  • Optimize Content and Metadata for Magento 2: Review and optimize all content and metadata during the migration. This includes updating keywords, descriptions, and tags to align with Magento SEO best practices.
  • Monitor and Address Any SEO Issues: Post-migration, closely monitor your website’s SEO performance. Use tools like Google Analytics and Search Console to identify and address any issues promptly.

#8 Post-Migration Issues

Despite extensive testing, issues can slip through and impact the live Magento 2 site after launch. For example:

  • Bugs affecting core functionality or flows.
  • Styling and layout issues.
  • Non-functioning extensions.
  • Performance slowdowns under full site traffic.


  • Thoroughly Test the Magento 2 Website Before Launch: Conduct comprehensive testing of the Magento 2 site to identify and fix any issues before going live. This includes functionality, performance, and user experience testing.
  • Address Any Bugs or Functionality Issues Promptly: Be prepared to address any bugs or issues that arise post-launch. A dedicated support team can help resolve problems quickly and efficiently.

#9 User Experience Challenges

The new Magento 2 UI inevitably involves a learning curve for customers used to the old system, which can impact user experience and satisfaction.


  • Communicate the Changes to Customers: Inform your customers about the changes coming with the Magento 2 migration. Provide details on what to expect and how it will improve their experience.
  • Provide Clear Guidance and Tutorials for the New Interface: Offer tutorials, FAQs, and customer support to help users navigate the new Magento 2 interface. This can include video guides, step-by-step instructions, and live chat support.
