Shopify Migration Checklist: Pre-Migration Steps

Step 1: Audit Your Current Store

Before migrating to Shopify Plus, a detailed audit is necessary. A website audit identifies the data that needs to be migrated and categorizes it by importance.

This step also identifies what should be left behind. High-revenue stores usually accumulate outdated content, broken redirects, unused integrations and apps, and legacy codes that can slow performance. These are things you don’t want to bring with you when you migrate. Migration is the ideal opportunity to clean up technical redundancies, streamline operations, and refine your online strategy.

A structured audit of your old website is what’s going to help you reduce risk, prevent valuable data loss, and help you build a more optimized Shopify environment from day one.

Start with:

• Export product data, customer data, and order history
• Document URL structures
• Identify top-performing pages and revenue-driving products.
• Review apps, integrations, and custom functionalities
  

Step 2: Back Up Everything

Even with a detailed audit, migration carries some risk. With this in mind, it’s important to note that before making any structural changes, one needs to create complete backups of your store’s data and assets. This includes databases, media files, theme files, and SEO metadata.

Having secure backups ensures that if anything goes wrong during the migration process, you can quickly restore critical information. For high-revenue stores, this safety net is essential because downtime or missing data can directly impact customer trust and revenue.

Make sure to back up:

• Website files and databases
• Product images and media assets
• Customer and order records
• SEO metadata and redirect rules

Even if you’re using automated migration tools, like  Matrixify, manual backups add an extra layer of protection.

Step 3: SEO Preservation Planning

SEO rank is something you want to safeguard during migration, as organic traffic is often one of the most valuable acquisition channels. A poorly executed migration can result in broken links, lost rankings, and significant traffic drops. That’s why SEO preservation should be at the top of your core Shopify migration checklist.

Start by mapping your existing URL structure to Shopify’s format. Since Shopify has its own URL hierarchy, you’ll need to prepare accurate 301 redirects from old URLs to their new equivalents. This ensures both users and search engines are guided to the correct pages.

It’s equally important to preserve on-page SEO elements, including:

• Title tags and meta descriptions
• H1 and heading structures
• Image alt text
• Canonical tags
• Structured data
  

You should also export your current XML sitemap and crawl your existing site using an SEO tool to capture all indexed URLs before migration. After launch, resubmit your updated Shopify sitemap to Google Search Console and monitor crawl errors closely.

When handled properly by Experts, migration can maintain and even improve your SEO ranking. But without structured SEO planning, recovery can take months.

Step 4: Evaluate Apps and Integrations

Shopify has an extensive and powerful app ecosystem, but not all previous integrations will transfer directly. Many legacy platforms rely on custom-built features or third-party extensions that may require a Shopify equivalent or redevelopment.

This stage of your ecommerce migration checklist should focus on reviewing your entire tech stack. Identify which tools are critical for running your business, which ones can be replaced with native Shopify functionality, and which should be retired. Migration is a smart time to simplify your systems and eliminate unnecessary subscription costs, opting for better, newer options that lead to efficiency.

Pay special attention to:

• Payment gateways
• Inventory management systems
• CRM platforms
• Subscription and recurring billing tools
• Analytics and tracking integrations

Step 5: Theme & UX Planning

Migration is not just a backend transition; it’s also an opportunity for you to improve the front-end and user experience of your website. Many brands opt to renew their design instead of replicating their old one, going for a more contemporary ecommerce website design, and also using migration as a chance to refine the customer experience.

The Shopify theme store featured a curated selection of ecommerce themes designed to enhance site speed and performance, all of which are mobile responsive and designed for checkout optimization. Shopify themes are also designed to enhance navigation clarity and product discovery.

Before migration, explore Shopify’s collection of themes. By combining a modern theme with intentional UX improvements, your Shopify store won’t just replicate your old site—it will perform better, engage customers more effectively, and support higher revenue from day one.

Post Ecommerce Migration Checklist

This section assumes that you’ve successfully migrated all your data to Shopify or Shopify Plus and have completed your launch. Once your Shopify store goes live, this doesn’t mean that the work is over. The post-launch phase consists of some basic checks and reviews that are critical for maintaining performance, ensuring smooth customer experiences, and preserving revenue streams.

Here is what to do after you launch on Shopify post-migration:

Test Everything Immediately

After migration, you need to monitor and test across every aspect of your store. Go to your website and confirm that the checkout process works flawlessly, all payment gateways are processing correctly, shipping calculations are accurate, email notifications are sent as expected, and discount codes function. Placing multiple test orders helps identify any issues before real customers encounter them. This stage ensures that the user experience is seamless and working up to standards.

Monitor SEO & Traffic

When migration is done right, it shouldn’t affect your SEO status, but it is worth monitoring your SEO and site traffic closely. Use tools like Google Search Console and analytics platforms to track indexing status, identify crawl errors, monitor traffic fluctuations, and check keyword ranking stability. Addressing any possible issues in the first few weeks can prevent long-term losses, maintain, or even improve search engine visibility.

Re-Submit Your Sitemap

After launching, generate a new Shopify sitemap and submit it to search engines, such as Google Search Console or Bing Webmaster Tools, and verify that your robots.txt file is configured correctly. Submitting your site map manually ensures faster indexing and that search engines crawl your new site efficiently, helping maintain your rankings and discoverability after migration.

Optimize for Performance

Although Shopify is optimized for speed, migration does leave behind bloat and redundancies found in your old website; additional performance checks can make a significant difference for high-volume stores. Best practices will have included compressing images, removing unused apps, monitoring page load times, and optimizing Core Web Vitals. These actions help your store maintain enterprise-level performance and improve the customer experience.

Communicate With Customers

If your migration includes design or functional changes, notify your customers proactively. Send email announcements highlighting exciting improvements, new features, or navigation updates. Clear communication reduces confusion, builds trust, and encourages customers to engage with your upgraded, better-than-ever Shopify-powered store.

By carefully following these post-migration steps, your high-revenue store can transition seamlessly to Shopify Plus while maintaining performance, SEO, and customer satisfaction.
