Magento to BigCommerce Migration
Use Nventory's product sync engine to move your Magento catalog to BigCommerce — configurable products, EAV attributes, images, and pricing all transfer automatically. Keep both platforms live with synced inventory while you validate BigCommerce, and cut over only when you're ready.
Migration Timeline
Estimated timeline for syncing your Adobe Commerce (Magento) product catalog to BigCommerce using Nventory.
Large catalog, custom functionality, or enterprise setup
Factors That Affect Timeline
- •Catalog size including configurable, grouped, and bundled product transformation requirements
- •Depth of EAV attribute usage and complexity of the attribute-to-custom-field mapping
- •Product image count and total file size affecting transfer time to BigCommerce's CDN
- •Number of product categories and depth of the category tree requiring hierarchy mapping
What Moves to BigCommerce
Nventory moves your product catalog so you can start selling on BigCommerce without rebuilding from scratch. Here's exactly what transfers and what doesn't.
Nventory Handles This
- Products & Configurable Variants
Nventory transforms Magento configurable products (parent entity + linked simple products via catalog_product_super_link) into BigCommerce products with options and SKUs.
- Inventory Levels
Nventory syncs Magento stock quantities across warehouses to BigCommerce inventory levels.
- Product Attributes & Custom Data
Nventory flattens Magento's EAV attributes (spread across entity type-specific tables) and maps them to BigCommerce custom fields.
- Categories & Navigation
Nventory maps Magento's nested category tree (using the nested set model in catalog_category_entity) to BigCommerce's category hierarchy, which supports full nesting.
- Product Images
Nventory transfers product images from Magento's media gallery to BigCommerce's CDN.
- Product Pricing
Nventory transfers Magento product pricing including regular price, special price, and tier pricing structures to BigCommerce's price, sale price, and bulk pricing fields.
You'll Handle Separately
- Customer accounts and data
Customer databases, saved addresses, and login credentials cannot be transferred between platforms through Nventory
- Order history
Historical orders and transaction records from the source platform cannot be migrated to the destination platform
- Magento custom module data in proprietary tables
Magento extensions store data in custom database tables with unique schemas (e.g., amasty_amtable, mageworx_seoextended). This extension-specific data has no BigCommerce equivalent and requires per-extension assessment to determine if the data can be exported and imported into a BigCommerce app or custom field structure.
- Magento's advanced catalog price rules and conditions
Magento's catalog and cart price rules support complex conditions including attribute combinations, customer group intersections, and date-range scheduling. BigCommerce's promotion engine handles many scenarios but does not replicate every Magento condition type. Complex stacking rules and attribute-based conditions may need simplification.
- Magento admin customizations and custom reports
Custom Magento admin grids, reports, dashboards, and mass actions built through modules do not transfer to BigCommerce's admin interface. These workflows must be recreated using BigCommerce's admin panel, API-driven tools, or third-party analytics platforms.
- Magento multi-website with separate root categories
Magento multi-website installations where each website has a completely separate root category tree and product catalog require separate BigCommerce storefronts. BigCommerce multi-storefront shares a single product catalog, so stores with isolated catalogs per website need architectural adjustments.
Powered by Nventory's product sync engine: The same reliable sync that keeps multichannel sellers in stock across platforms also powers your migration. Your Adobe Commerce (Magento) catalog syncs to BigCommerce and stays in sync — run both stores in parallel until you're ready to switch.
Things to Consider
Platform-specific details and how they affect this integration.
Magento's EAV database design allows unlimited product attributes with per-store-view values. BigCommerce custom fields are simpler — they support text, date, and number types but lack Magento's attribute validation rules and input renderer types. Attributes used for Magento's faceted search may need restructuring as BigCommerce's product options or facet-enabled custom fields.
Nventory reads Magento's EAV tables with full scope resolution and maps each attribute to the most appropriate BigCommerce field type. Attributes used for filtering become BigCommerce facet-enabled fields. The complete mapping is reviewable before sync execution.
Who Should Migrate from Adobe Commerce (Magento) to BigCommerce
Common scenarios where a Adobe Commerce (Magento) to BigCommerce migration makes sense.
Migration Process
A structured, step-by-step migration through Nventory.
Adobe Commerce (Magento) → Nventory → BigCommerce
Connect Both Platforms
Connect your Magento instance and your new BigCommerce store to Nventory. Nventory reads your Magento product catalog, EAV attributes, and category structure to prepare the data for sync.
Sync Your Product Catalog
Nventory syncs your complete product catalog from Magento to BigCommerce — configurable products transform into BigCommerce product options, EAV attributes map to custom fields, and images transfer to BigCommerce's CDN.
Enable Inventory Sync
Nventory enables real-time inventory sync between Magento and BigCommerce. Stock levels stay consistent across both platforms so you can sell on either without overselling.
Sell on Both, Switch When Ready
Run both stores in parallel with Nventory keeping inventory synced. Validate your BigCommerce setup, test checkout, and confirm product data accuracy. Cut over on your timeline.
Frequently Asked Questions
BigCommerce supports complex catalogs with product options, custom fields, and price rules. While the data model differs from Magento's EAV approach, Nventory transforms your catalog structure to leverage BigCommerce's native features without losing product detail or relationships.
BigCommerce has native B2B features including customer groups, price lists, quote management, and purchase order support. Most Magento B2B extension functionality has direct BigCommerce equivalents. Customer data migration is outside Nventory's scope, but Nventory migrates your product catalog and pricing structures.
BigCommerce has its own REST and GraphQL APIs. Custom integrations built against Magento's API will need to be updated to use BigCommerce's endpoints. Nventory migrates the data but API integration code needs to be adapted by your development team.
BigCommerce's multi-storefront feature serves a similar purpose to Magento's multi-website setup. Each storefront can have its own domain, theme, and product selection while sharing a single catalog and inventory pool.
The initial catalog sync typically takes 8-48 hours depending on catalog size, EAV attribute depth, and image volume. Nventory keeps both Magento and BigCommerce live with synced inventory throughout the transition, so there is zero downtime — you continue selling on Magento while validating BigCommerce and switch DNS only when everything is confirmed.
Nventory transfers products, configurable variants, EAV attributes, category hierarchies, images, pricing, and inventory. Customer accounts, order history, custom module data in proprietary tables, admin panel customizations, catalog price rule logic, and Magento theme code don't transfer — these require BigCommerce-native rebuilds or third-party migration tools.
BigCommerce supports custom fields but has a limit of 250 custom fields per product and a 255-character value limit per field. If your Magento EAV attributes exceed these limits, Nventory's sync log flags which attributes were truncated or skipped. For attributes that don't fit, consider consolidating related fields into a single structured custom field or using BigCommerce metafields via the API as an alternative storage approach.
