Insights from Our Experts

FAQs about eCommerce Migration Services

Our platform migration approach starts with auditing of your current platform. We validate data, map your SEO, run parallel tests, and then build a plan for you. This helps you gain stability and performance. Once this is done, we plan the migration that best suits your current business needs. 

Yes. We specialize in monolith-to-headless migrations using MACH principles, current frontend frameworks, and API-led integrations, allowing brands to migrate faster without backend dependency.

The time it takes to replatform depends on the size and complexity of your website. It also depends on the changes you want to make. Our replatform process takes an integrated approach that allows for different steps to be executed simultaneously. 

You can take small steps at once to ensure your replatform focuses on the most important issues initially, rather than fixing everything at once. 

Everything that is a part of your current ecommerce store is included during migration. This includes the products, the blogs on your website, landing pages, metadata, customer accounts, and other essential things. We plan your migration in a way that it’s carried out so you don’t lose anything. 

You don’t need to take on an entire platform migration if you’re moving from Basic Shopify, Shopify, or Advanced Shopify to Shopify Plus. Instead, you’ll contact Shopify’s team to negotiate your Shopify Plus rate, and then your Shopify store will be upgraded to the Plus plan. After a full business day, you should be on Shopify Plus.

 

Here are the indicators that tell you it’s essential to migrate from your existing platform to another:

  • Slow website performance
  • Difficulty scaling during peak traffic
  • Limited integration capabilities with ERP or third-party systems
  • Outdated technology, rising maintenance costs, and restricted customizations


You can also migrate when expanding to new markets, adding complex product catalogs, implementing AI-driven capabilities, or shifting from legacy platforms to more scalable solutions like headless commerce or cloud-based platforms.

Common challenges during ecommerce data migration include inconsistent or duplicate product data, mismatched data fields, broken relationships between products and categories, incomplete customer records, and difficulties transferring order history. Businesses may also face SEO risks from broken URLs and integration issues with ERP or CRM systems. Klizer minimizes these risks through detailed data audits, precise data mapping, automated validation checks, and structured SEO redirect planning. Our team also tests integrations in staging environments and follows a controlled go-live process to ensure a smooth, disruption-free migration.
