Custom Fields Migration

What are custom fields in general and why do you need it?

1. What are custom fields?

Custom fields are fields which originally does not exist in your platform core. They are created through a plugin or module built by the platform’s developers or other plugin providers. They can also be created by directly modifying your database. You use custom fields to specify additional information to your products or pages.

Below is an example of Custom Field created by Product Brand Plugin on WooCommerce:

2. Why is custom field necessary?

Custom field allows you to extend the power of the platform you are currently using. There are some situations in which you will need a function or field that is not in default of your platform, that’s when custom field comes in handy.

For example, you can use custom fields to add specific information to your Customers or Products such as: Price, weight, color or dimensions, etc.

This will make it easier for your customers to filter products or information on your websites to find what they really want, based on the fields you set up.

What are custom fields in migration?

When migrating your store on current platform to another, it’s important to transfer everything over including custom fields. Otherwise, you will have to establish everything again manually.

Custom fields are defined slightly different in migration process from its original meaning. There are three types of data field which will be considered custom fields including:

  1. Fields which are in the Source cart’s default but aren’t in the Target cart’s.
  2. Fields which are not in both the Source cart’s and Target cart’s default.
  3. Fields which are custom in Source cart but available in Target cart.


  • Your custom fields in Source store may be created by a popular plugin (e.g. Product Brand, Preserve Order number plugin in WooCommerce and Product review in PrestaShop). If these fields are in the Target store’s default, our team can consider it a default field.
  • Many source carts have the ability to create their own custom field in the backend. These fields are not considered custom fields as per our terms and CAN BE MIGRATED automatically.

LitExtension can transfer the data in custom fields for you by customizing our tool based on the their structure.

Let’s suppose you want to migrate from 3dCart to WooCommerce. In your 3dCart website, there are additional information stored in fields from 1 to 13 as follows:

3dcart custom fields
3dCart custom fields

These fields are displayed as tabs on your 3dCart website’s front end:

3dcart custom fields
3dCart custom fields

However, when migrating your store to WooCommerce, this platform does not allow you to show the fields in the old way because it only supports attributes. Therefore, your additional information will not be displayed in separate tabs but a common one as shown below:

migrate custom fields to woocommerce
Migrate custom fields to WooCommerce

If you want the information to be displayed the same as on your Source store, you need to install Custom Product Tabs plugin into WooCommerce.
