Why migrate to Swell?

Before diving into the how, let’s understand the why. Swell offers several compelling advantages over Shopify:

• Flexible architecture: Build unique shopping experiences with complete design freedom while maintaining powerful backend functionality.
• Native subscription support: Unlike Shopify where subscriptions feel like an afterthought, Swell has subscription functionality built into its core, making it more reliable and customizable.
• Shopify theme compatibility: Swell's Proxima storefront can actually run your existing Shopify 2.0 themes, making the transition smoother.
• API-first design: Full backend API access gives you unprecedented control over your store data and functionality.

Understand your migration options

Swell offers several migration paths depending on your technical comfort level:

Option 1: CSV import (easiest for non-technical users)
This is the most straightforward method and requires no coding knowledge. You'll export your data from Shopify as CSV files and import them into Swell through the dashboard. This method works well for:

• Products and product information
• Customer data and accounts
• Basic inventory information

Option 2: Theme upload (keep your current design)
If you're using a Shopify 2.0 theme, you can often upload it directly to Swell's Proxima storefront. This means you can keep your current design while benefiting from Swell's backend capabilities. This is a huge advantage that most other platforms don't offer.

Option 3: Developer-assisted migration (for complex stores)
For stores with custom apps, complex workflows, or technical integrations, working with a developer to use Swell's migration API might be necessary. However, most small to medium-sized stores won't need this level of complexity.

Option 4: FlexiPort automated migration (fastest for large catalogs)
For stores with large catalogs or complex data structures, FlexiPort offers AI-powered automated migration directly to Swell. Instead of manually mapping fields, FlexiPort analyzes your data, handles inconsistencies, and transfers everything via Swell's API—typically in one business day. This is ideal for stores with 1,000+ products where manual CSV work becomes impractical.

What requires special attention:

• Customer passwords: For security reasons, passwords cannot be migrated. Your customers will need to reset their passwords on your new Swell store. You'll want to communicate this clearly to them.
• Product Images: Images hosted on Shopify will disappear once you close your Shopify store, so you'll need to re-upload them to Swell. Swell provides a batch import feature to make this easier.
• Payment information: Stored credit card information will need to be handled carefully and may require customers to re-enter their payment details.
• Shopify Apps: Custom apps and Shopify-specific integrations will need to be replaced with Swell-compatible alternatives.

Timeline expectations

Plan for a minimum of one week for a complete migration, depending on your store’s complexity.

• Small stores (under 100 products): 2 - 3 days
• Medium stores (100 - 1000 products): 1 - 2 weeks
• Large stores (+1000 products): +3 weeks
