Custom Plugin & Addon Data

Why Custom Plugin & Addon Data needs Custom Migration

Many stores run on Magento modules, WooCommerce plugins, PrestaShop modules, OpenCart extensions, or Shopify apps. That data often lives in custom tables, option keys, or app metafields—outside standard products, customers, and orders. Cart2Cart Custom Migration for plugin & addon data scopes what must move and how it should land on the target platform.

Who this customization is for

• Stores whose checkout, pricing, or fulfillment depends on plugin-stored data
• Merchants with subscriptions, bookings, memberships, gift cards, or loyalty plugins
• Teams moving Magento modules or Woo plugins to a cart without a 1:1 app equivalent
• Businesses that need a map-or-rebuild decision before go-live

Common use cases

• WooCommerce plugin tables (subscriptions, bookings, memberships, product add-ons, wholesale)
• Magento module data (custom EAV, flat tables, module-specific attributes)
• Shopify app metafields or exported app data remapped after a platform change
• Loyalty points, gift cards, wishlists, or review plugins with their own storage
• B2B / ERP companion plugins storing account-level pricing or approvals
• Rebuilding critical addon behavior when no target equivalent exists

What Cart2Cart customizes

Migration Experts inventory plugin tables and configuration, identify business-critical records, and design export/import or rebuild rules. Where the target has no matching app, we map valuable fields into native entities, metafields, or a documented handoff for your developers.

Platform considerations

Plugin schemas are unique per extension. Feasibility depends on readable data, APIs, and target counterparts. Custom Migration starts with an inventory—not assumptions that “all plugins migrate.”

Note: The Target platform may require installing additional apps, plugins, or add-ons when a capability is not available by default. Custom Migration can map and import the data, but those Target-side apps/plugins often need to be installed and configured so the feature works in admin and on the storefront.

The best way to make sure everything is mapped correctly is to run a Demo Migration with your real Source platform data, then carefully check how entities look on the Target store before Full Migration.

Checklist for evaluating this customized migration

• Inventory plugins/modules/apps and which store must-keep business data.
• Identify custom tables, option keys, or app metafields involved.
• Decide map-to-native, metafield, or rebuild when no target equivalent exists.
• Prioritize features that break checkout, fulfillment, or B2B if missing.
• Validate sample plugin-driven records after Demo before Full Migration.

How to apply for this customization

1. Open Custom Migration or Schedule a Call and mention plugin / addon data.
2. List source/target carts plus plugins, modules, or apps that store must-keep data.
3. Share plugin names, versions, and key tables or metafields if known.
4. We assess feasibility, propose a map-or-rebuild plan, Demo-check samples, then schedule Full Migration.

Self-service Additional Options vs Custom Migration

Plugin/module/app tables are outside standard Wizard Additional Options. Self-service covers core entities and the options listed on other Custom Migration pages; addon data needs scoping with Migration Experts.

• Core entities + Additional Options only — Self-service: Use the Wizard for products, customers, orders, and documented Additional Options. Choose Custom Migration when: Custom Migration to inventory plugin tables/metafields and map or rebuild what checkout, B2B, or fulfillment depends on.

Availability depends on your Source → Target pair—confirm checkboxes in the Migration Wizard Entities / Additional Options step. See the Additional Options guide and Additional Options FAQ for pair-specific details. If Wizard options are not enough, schedule a Custom Migration call.

Already ran a self-service migration?

Yes—you can still apply this Custom Migration after a Wizard (self-service) run. Cart2Cart can restart migration with the customized rules; the Target store typically needs Clear current data on Target Store before Migration (or an equivalent cleanup of the entities from the previous self-service migration) so customized results are not mixed with the old import. Share your Source/Target carts and what already moved—Migration Experts will confirm the safest clear-and-rerun plan before Full Migration. Schedule a call if you already completed a Demo or Full Wizard migration and need customization next.

What we need to scope plugin & addon data

Third-party plugin tables and app metafields are the most store-specific layer of a migration: the same plugin version can store different custom columns depending on settings and other addons.

The preferred approach is staging or production access so we can identify installed plugins, their data tables, and what must move vs stay behind. If you cannot grant access, a full or plugin-scoped database dump can be analyzed offline; that work typically requires a deposit for environment setup and schema discovery before we estimate the Custom Migration.

Tip: Initial data-structure analysis is much more efficient when you prepare exact examples of the important attributes and fields on the Source, plus how each should be mapped on the Target store (sample products/customers/orders with field names, values, and desired Target destinations). Clear examples reduce discovery time and help Migration Experts quote and implement the customization accurately.

FAQs

Do you migrate the plugin software itself?

No—we migrate data. Installing/configuring replacement apps on the target is separate.

What if there is no equivalent app on the new cart?

We extract critical fields into native/metafield storage or provide a rebuild brief for your developers.

How do we prioritize which plugins matter?

Start with anything that affects checkout, money, fulfillment, or B2B pricing.
