Shopify Theme Migration: A Simple Guide

When you use Shopify to run your eCommerce shop, eventually you'll outgrow your introductory theme. Either because your eCommerce shop is expanding, or because you're ready for a complete makeover, you'll need to migrate to a new theme.

That's where theme migration comes into play.

In this article, we will define and describe what Shopify Theme Migration is, the significance of performing it properly, and how a professional team such as Alien Web Solutions can assist in completing the migration process quickly and easily.

What is Shopify Theme Migration?

Shopify theme migration is the transfer of your store from one Shopify theme to another while retaining all content, data, and functional elements of your current shop. In layman’s terms: You are updating the appearance of your shop and moving to a new theme with assurance that your current shop is safe and continues functioning.

Examples of content, data, and functional elements of your store that will not be lost in the migration process include:

  • Product Listings
  • Collections
  • HTML pages
  • Images
  • Third-Party Applications/Integrations

Why Would You Use Theme Migration?

Theme migration can be required for various reasons, including but not limited to:

  • An old store design
  • Improved page speed/performance
  • Additional customizations
  • A mobile device-friendly layout
  • As your business expands, the design of your store could be improved

A great theme can enhance the user experience and generate increased sales.

What Are The Challenges Associated With Theme Migration?

Migrating themes is not always a straight-forward process. There are common challenges associated with migrating a theme, including but not limited to:

  • Design Setting Loss
  • Layout Disruptions
  • Missing Custom Coding
  • Third-Party Application Compatibility Issues
  • Potential SEO Damage If Migration is not Completed Properly

The key is to take extra precautions when completing a migration.

Steps to Migrate to a New Theme

Theme migration requires an implementation of themes incrementally over time.

1. Backup Current Theme

Before the process begins to prevent losing any data, backup existing theme files using FTP.

2. Choose a New Theme

Choose your new theme that is relevant to your business and design goals.

3. Install and Setup New Theme

Installing your new theme involves downloading the theme and following the instructions provided by the theme developer.

4. Transfer Content

Transfer necessary information such as section information, banners, product information, and landing pages from the old theme to the new one.

5. Customize New Design

Once the new theme has been implemented, make any necessary adjustments so the new theme matches your company's brand.

6. Testing

The following areas of your new theme must be evaluated for functionality:

  • Mobile view
  • Site load speed
  • Checkout process
  • App functionality

7. Launch the New Theme

Once you have confirmed the new theme is functional throughout the entire site, go ahead and launch the new theme.
