Shopify 2.0 is designed to offer greater flexibility, faster performance, and more customization options. But migrating to this upgraded version isn’t just about hitting the “update” button. It’s about understanding what changes under the hood, how your store’s data will move, and how to avoid common pitfalls during the process. In this blog, we’ll walk you through the technical aspects of migration, highlighting the problems you might encounter and the solutions Shopify 2.0 offers.

So, let’s break down what this migration really involves and why it’s worth the effort.

What is Shopify and Shopify 2.0?

Source

Shopify is one of the largest eCommerce platforms globally, whose rise to prominence can be attributed to its accessibility, ease of use, and constant evolution to meet the needs of businesses.

In 2021, Shopify introduced its biggest upgrade yet—Shopify 2.0. This new version isn’t tied to any specific plan and offers a range of exciting features, including a revamped theme architecture, enhanced customization options, and improved design flexibility. With the introduction of JSON templates alongside the existing Liquid templates, Shopify 2.0 allows for deeper customization, enabling businesses to create more personalized and visually engaging online stores.

Upgrading to Shopify 2.0 is optional, but it’s strongly recommended for businesses aiming to grow, enhance performance, and provide a better shopping experience. This upgrade addresses several challenges faced by eCommerce businesses, such as slow load times, limited customization options, and clunky design elements.

What are the Key Differences Between Shopify 2.0 vs Shopify 1.0?

Shopify 2.0 is a major upgrade, offering more flexibility, faster performance, and enhanced customization compared to Shopify 1.0. While Shopify 1.0 relied on static layouts and limited editing capabilities, Shopify 2.0 introduced dynamic sections, metafields, and better developer tools, making it easier to build and scale online stores. Here’s a closer look at the biggest improvements.

1. Revamped UI & Theme Improvements

Shopify 1.0’s default theme, Debut, was functional but had limited customization. Shopify 2.0 introduces Dawn, a modern, mobile-friendly theme optimized for speed, media-rich product pages, and flexible free themes. Businesses can now create visually engaging storefronts with announcement bars, high-resolution images, and better product storytelling.

2. Faster Load Times

Speed is a game-changer in Shopify 2.0. The Dawn theme loads 35% faster than Debut, thanks to optimized JSON templates and app extensions running on Shopify’s servers instead of client-side JavaScript. These improvements enhance page load speed, create a smoother browsing experience, and make the checkout process significantly faster.

3. More Customization Across the Site

Shopify 1.0 allowed merchants to customize only the homepage with sections. Shopify 2.0 removes that limitation, enabling sections on every individual page. Merchants can add up to 25 sections per page and 50 blocks per section, making it easier to structure pages exactly how they want without needing custom code.

4. Metafields for Advanced Customization

With meta fields, Shopify 2.0 allows businesses to store and display custom data like product details, size charts, part numbers, or release dates—all without third-party apps or manual coding in the Shopify admin. Metafields work across products, collections, pages, and orders, allowing for more dynamic and data-driven storefronts.

5. App Blocks for Greater Flexibility

Shopify 2.0 introduces App Blocks, making it easier to add and manage app-powered elements within themes, including those in a vintage theme. Merchants can now integrate 3D models, live pricing updates, product reviews, and star ratings directly into their store design without modifying Liquid code. Elements can be added, removed, or reordered with a simple drag-and-drop interface.

6. Improved Developer Tools

For developers, Shopify 2.0 enhances workflow efficiency with new tools like GitHub integration for version control, an upgraded Shopify CLI for faster theme development, and Theme Check for debugging Liquid code. The improved Theme Editor simplifies design adjustments, while Theme App Extensions reduce reliance on custom Liquid coding, making store management more seamless.

How to Migrate to Shopify 2.0 (Step-by-Step Guide)

Migrating to Shopify 2.0 isn’t just about upgrading your store—it’s about unlocking better performance, customization, and flexibility. The process can be smooth if you follow the right steps. Here’s how to do it:

Step 1: Assess Your Current Shopify Store

Why it matters: Before making any changes, you need to understand how your current store functions.

1. Review your theme, apps, and custom code to see what might need updates.

2. Check if your existing theme has a Shopify 2.0 version available.

3. Identify custom scripts or third-party integrations that could break during migration.

Tip: Shopify offers a Migration Assessment tool to help determine the best path for your upgrade.

Step 2: Choose Your Upgrade Method

There are three ways to migrate, depending on how much customization you need:

1. Download a New Shopify 2.0 Theme (Best for those who want a fresh start)

2. Head to the Shopify Theme Store and select a 2.0-compatible theme like Dawn.

3. Customize it using the new drag-and-drop sections and metafields.

4. Update Your Existing Theme (Best if your theme has a 2.0 update available)

5. Check if your current theme has a 2.0-compatible version.

6. Install the update and test your store to ensure everything runs smoothly.

7. Manually Migrate Your Theme (For those using a heavily customized theme)

8. Convert your Liquid template files to JSON templates.

9. Move Liquid or HTML code into sections to unlock drag-and-drop editing.

10. Add App Blocks for better customization without affecting your theme code.

Tip: If you’re unsure, consult a Shopify development expert like The Genie Lab to avoid breaking your store’s layout.

Step 3: Back Up Your Store Data

Why it matters: Migration involves modifying core files, so having a backup ensures you can revert if needed.

1. Duplicate your theme in Shopify’s admin panel.

2. Export key store data (products, customers, orders) as CSV files.

3. Save copies of any custom scripts or Liquid code.

Tip: Use Shopify’s Rewind App for automatic backups.

Step 4: Implement Shopify 2.0 Features

Once your theme is upgraded, it’s time to unlock the real power of Shopify 2.0.

1. Use Sections Everywhere to customize product pages, collections, and more.

2. Add Metafields for extra product info (e.g., size charts, material descriptions).

3. Use App Blocks for reviews, pricing tables, and other interactive features.

Tip: Test new features on a duplicate theme before applying them to your live store.

Step 5: Test & Optimize

Why it matters: A glitchy site can hurt sales. Always test before going live.

1. Check for broken pages, missing images, and app conflicts.

2. Run a speed test using Google PageSpeed Insights.

3. Test checkout and mobile responsiveness.

Tip: Get feedback from a few real customers before launching your updated store.

Step 6: Launch & Monitor Performance

Your migration is complete, but your job isn’t over yet.

1. Monitor site traffic and conversion rates to see how the new setup performs.

2. Keep an eye on SEO rankings (some theme changes can affect them).

3. Track app performance—remove outdated or conflicting ones.

Tip: Set up heatmaps (using tools like Hotjar) to understand how visitors interact with your new layout.

What Data Will Be Migrated During Shopify 2.0 Migration?

Migrating to Shopify 2.0 ensures that your store retains all essential business data while gaining access to new features and optimizations. The process involves transferring key elements to maintain continuity and functionality.

1. Product Data

All product listings, including titles, descriptions, pricing, SKUs, inventory levels, and images, will be migrated to Shopify 2.0. This ensures that your storefront remains consistent, with no loss of product details.

2. Customer Records

Customer profiles, including names, contact details, order history, and saved addresses, will be transferred. This allows businesses to maintain their customer relationships without disruption.

3. Order History

Past orders, transaction details, invoices, and payment records will be preserved. This is crucial for customer service, accounting, and reporting purposes.

4. Store Settings

Core store settings, including shipping rates, tax configurations, and payment gateways, will carry over. However, merchants may need to review and optimize certain settings, such as the URL structure, to align with Shopify 2.0’s new customization capabilities.

5. Theme and Customization Elements

Themes and design customizations do not migrate automatically. If your store is using a Shopify 1.0 theme, a manual migration is required to rebuild the design within the new version of your current theme in Shopify 2.0. However, merchants using custom-coded elements may need to adjust them to align with the platform’s new framework.

What are the Potential Challenges in Migration?

Migrating to Shopify 2.0 offers significant benefits, but it’s important to be aware of the technical challenges that could arise during the transition. Addressing these challenges upfront can ensure a smoother migration process.

1. Compatibility Issues with Existing Third-Party Apps

Some third-party apps built for Shopify 1.0 may not be fully compatible with Shopify 2.0 due to differences in the underlying platform architecture. Certain apps may require updates or replacements from app developers to work seamlessly with the new version, impacting functionality and user experience.

2. Learning Curve for JSON Templates

Shopify 2.0 uses JSON templates, which may require technical expertise in coding languages like CSS to fully understand and customize. Merchants with little coding experience may face difficulties in utilizing these templates effectively, especially when making adjustments to page layouts or integrating advanced features.

3. Need for Theme Restructuring

Shopify 1.0 themes are built on a different architecture, and when migrating to Shopify 2.0, you may need to completely restructure your theme using the new theme architecture. This involves rebuilding sections and templates to ensure compatibility with Shopify 2.0’s flexible section-based customization and dynamic elements.

4. Possible Loss of Custom-Coded Elements

Custom-coded elements from Shopify 1.0 may not directly transfer to Shopify 2.0. Shopify 2.0’s new architecture, including the use of app blocks and JSON templates, might require the redevelopment of custom functionality, which can be time-consuming and potentially costly.

5. Testing Requirements Before Launching

After migration, extensive testing is necessary to ensure everything works as expected. This includes checking the performance of apps, theme responsiveness, checkout flow, and data integrity. Any errors or issues uncovered during testing need to be resolved before the store goes live.
