Replatforming your website to Shopify or Shopify Plus can be quite the experience. While perhaps a little daunting, proper planning can mitigate the chances of failure or costly errors along the way.

In 2026, we see many brands ready to migrate their entire online operations onto the Shopify platform, with the promise of a faster, cleaner online store experience, packed with cutting-edge tools for ecommerce. For a lot of brands, switching to Shopify isn’t about hype; it’s about finally getting onto a platform that supports how they want to do business.

But here’s the part that concerns brands that are thinking of replatforming to Shopify or Shopify Plus: Shopify migrations can hit roadblocks when not handled with proper planning and care, roadblocks that will have you missing your launch date or running into budget overruns.

Behind every online store is a wealth of data, SEO equity, custom features, third-party integrations, and operational workflows that have kept the business running. When even one of those pieces gets overlooked during the Shopify migration process, the new launch may need a reschedule to deal with the hangups.

If you’re thinking about migrating to Shopify, you probably have these concerns in mind:

• Organic traffic drops because of poor Shopify SEO migration
• Products or orders don’t import correctly
• Integrations break
• Checkout errors
• Costs or budget spiral
• Teams scramble post-launch, trying to figure out what went wrong or how to manage the new site.

A successful Shopify migration isn’t about simply moving your website. It’s about protecting and maintaining or upgrading your business while you successfully move your data, your SEO, and your operations. The ideal Shopify migration should be done in a way that no downtime to your business is needed, so that your customers don't even notice an interruption.

In this article, we break down the real reasons Shopify migrations fail, so you can be aware of the common pitfalls to avoid.

1. Inadequate Planning

A lot of brands approach Shopify migration thinking it’s basically a copy-and-paste kind of job, where you simply move the products, move the pages, and launch the new site. However, most stores have a complexity to them, especially the elements that are more behind the scenes. Think about your own store for a moment, the complexity and processes you’ve built over the years. You probably have:

• Custom product logic
• Customer data
• Apps you installed
• Discount rules
• Unique fulfillment workflows
• Years of SEO work

When planning is rushed or simply not done carefully enough, these things get missed, and you don’t want these pitfalls to show up after launch.

It’s worth noting that most migration problems don’t come from Shopify itself; they come from poor planning and discovering what the store actually needs to function right when you think you're ready to launch or even post-launch.

A clear plan laid out before the migration process even begins means fewer surprises, smoother development, and a migration that supports rather than disrupts the business you’ve been building for years.

2. Messy  Data Migration

Your store’s data is the core of your business, so it needs to be preserved during the migration process. This data includes product, variants, inventory counts, customer accounts and data, past orders, discount codes, giftcard codes, metafields, and more. Every piece of it plays a role in how your store runs day to day. The challenge? Most data isn’t as clean or organized as people think it is, especially if your store has been running for a few years.

You might have:

• Old product records that were never updated
• Duplicate SKUs
• Complex variants not supported by Shopify
• Incorrect URL mapping
• Discount codes that were created for one-off promos

When this data gets imported into Shopify without proper cleanup or checks, problems start showing up fast. How to avoid it? Successful migration to Shopify means cleaning up and making sure your data is well-structured. This means auditing your present site before migration.

It may feel tedious, but it’s the difference between a smooth launch and a messy one. Remember, clean data doesn’t just make your migration safer, it makes your business easier to manage post-launch.

3. SEO Problems & Lost Traffic

SEO—something you’ve built brick by brick, with every post, every webpage, earned backlinks, and across meta fields. You want to ensure a successful Shopify SEO migration because this isn't something you built overnight, and the last thing you’d want is to lose your SEO ranking because of replatforming.

Even a single broken redirect or a few missing pages can cause rankings to drop within days. This is because SEO relies on consistency, and SEO issues are one of the most common and most expensive consequences of a poorly executed migration. But it’s completely avoidable when handled right.

Here are the problems we see most often:

• No 301 redirect plan
• Changing URL structures without a strategy
• Missing metadata, alt tags, or canonical tags
• Broken internal links
• Sitemap not updated or submitted

A careful SEO migration protects your traffic, your rankings, and your revenue.

4. Broken Integrations and Apps 

A lot of stores rely on a mix of apps or custom integrations that help them run and customize their business. These apps help with everything, from shipping, inventory, collecting and displaying reviews, managing subscriptions, analytics, you name it. These apps are what quietly run the business, so when one stops working after the Shopify migration, the impact is immediately felt.

Here’s the problem: not every app or integration works the same way on Shopify as it did on your old platform. Thankfully, with Shopify’s vast collection of apps from their App Store, so chances are, your old app exists on Shopify. If not, then there may very well be an alternative app. However, some features need custom development, or you may have to have a developer develop a custom app, but this isn’t always the case.

Just ensure that before you migrate, you've listed down the tools your business relies on, including apps, so you can find the same apps, something similar, or go for custom solutions.

5. Inadequate Testing

You can’t launch your newly migrated Shopify website without first letting it undergo a thorough test. That’s because even a well-planned migration can go wrong when testing isn’t given as much importance as it should. Pre-launch testing and conducting Q&A is when you catch the issues that would otherwise frustrate customers, disrupt fulfillment, or damage the trust of hard-earned customers the moment you go live.

When testing is skipped or incomplete, issues like:

• Checkout errors go unnoticed
• Broken links stay unresolved
• Discounts and shipping rules fail
• Fulfillment workflows break
  

These are just some of the things that can go wrong, but really, there's more, and many of these problems only surface after real orders start coming in, when fixing them is more stressful and costly. A successful launch means everything works smoothly the second your site goes live, with no disruptions to your business and your customers.

It’s important to test every critical flow and to launch only when everything behaves exactly as expected.

6. Budget or Timeline Overruns

Budget overruns or going over the original Shopify migration budget can happen when your team uncovers an unexpected element of migration complexity that requires extra work, like additional apps or integrations. What starts as a “simple platform switch” can quickly become a larger project with surprise additional costs cropping up, mostly due to having a poorly scoped out project, changing one’s mind about a feature mid-project, or a rushed discovery phase.

Budget overruns happen when:

• Integrations require more work than expected
• Custom features weren’t identified early
• There is no clear decision-maker on the project
• Requirements change midway through development

These surprises tend to add development time, require new apps, or lead to last-minute fixes that increase the overall cost. To avoid this, it’s best to set realistic timelines, define a clear scope from the beginning of the project, assign a decision-maker, and work with experienced migration experts who know what to look for early. A well-defined scope protects both the designated launch date and the budget.
