Unlike diamonds, ecommerce migrations are not forever. Here are some principles to consider the next time you have to face an Ecommerce replatforming.
eCommerce migrations can be scary. But, like many other scary things, they can be worth it. The million-dollar question — or at least the a‑lot-of-dollars question — is how to tell whether yours will be. Read our replatforming guide and find out.

The first question opens up a lot of others, most of them potentially expensive and potentially very profitable. When is it a good idea to change eCommerce platforms? What are the advantages and disadvantages of the jump? Is there any way to make the most of the pros — and reduce the impact of the cons — of the migration process?
It is possible that the answer to most of these questions is that it depends. The right eCommerce platform for your business depends on your organization’s specific needs, on the platform you’re leaving behind, on the platform you’re considering moving to (here’s our recommendation) and on how you plan to handle the move.
In this guide, we cover the questions we hear most, and share a few answers based on what we’ve learned from doing this many times — to help you decide if, when, and how to migrate to a platform that works for you and not the other way round. Play it, Sam.
Replatforming becomes a viable option when your current platform starts causing more headaches than it solves, and more fears than it calms.
In a nutshell, the triggers relate to three things — poor performance, poor scalability, or poor you (high or unpredictable costs) — and combinations thereof. Here are the most common scenarios.
The first scenario in which it would be a good idea to migrate your eCommerce site is inadequate performance. This can manifest in various ways and it can be a common issue with legacy, monolith platforms. Some examples include poor customer experience, inefficient processes, difficulties to handle increased traffic, slow page load times, outdated web experiences, frequent downtime or increased security threats, a particularly critical factor that might call for an ecommerce migration plan to protect your business and your customers’ sensitive information.
If your website is not functioning as it should or is unable to keep up with the demands of your business, replatforming can provide an opportunity to overcome these limitations.
Migrating to a new eCommerce platform can help improve the overall performance of your site, resulting in a better experience for your customers. This can include faster page load times, improved navigation, and increased security measures to protect against cyber threats. By addressing these issues, you can enhance the overall functionality and efficiency of your website, ultimately leading to increased sales and customer satisfaction.
Additionally, a successful migration can also provide an opportunity to update the design and user interface of your site, giving it a fresh and modern look that can attract new customers and retain existing ones.
Another scenario in which replatforming may be a good idea is not related to what your site is doing now, but to what you may need it to do in the future.
As customer needs constantly evolve, your platform should be able to adapt and add new features to meet those demands. For example, if your existing solution cannot provide an omnichannel selling option or lacks flexibility in customization, replatforming becomes a strategic move to make sure you can meet your evolving requirements.
Flexibility and scalability are key features to look for when considering the best eCommerce platform for your business, because you don’t want your own platform to be the reason why your company is unable to grow to its fullest potential. If your current platform is not equipped to support your company’s growth and becomes a hindrance rather than an enabler, it’s probably the right time to explore other options.
Furthermore, replatforming can also be beneficial if you are looking to expand your business globally. Different regions have different payment methods, shipping regulations, and tax laws, and your current platform may not be able to accommodate these variations. This can result in a poor user experience and hinder your international growth. A platform with proper localization and internationalization capabilities makes cross-border growth possible instead of painful.
Or over (your) head. A third scenario is that your existing solution does what it should, and can therefore still be called an eCommerce solution, but at a great cost, or (possibly) worse, at unforeseeable costs.
Legacy platforms can have a higher TCO (total cost of ownership) than newer, more streamlined options, which means you are spending more resources just to keep the site running. High operational costs, expensive resources, such as dedicated developers, and inability to develop new features or updates quickly can weigh down your business and limit your ability to innovate.
Another thing to watch out for is hidden costs, a common downside of several technically “free” solutions. Maintenance costs, expensive plugins, and customization that requires high cost development solutions can drain your resources.
An efficient platform should let you make custom changes, scale your business, and innovate without breaking the bank. If your current platform is causing financial strain, resourcing issues, and difficulties in developing new features or updates when you need them, it’s time to explore alternative options. Migrating to a better platform can streamline your operations, reduce costs in the long run, and help with the challenges associated with managing and maintaining your eCommerce platform.
Ultimately, an ecommerce replatforming process is not about giving your site a purely aesthetic makeover but about future-proofing and growth-proofing your business. It might be challenging, but if you find that your current platform is hindering your ability to scale, make custom changes or address existing problems, and generally speaking, causing more problems than it solves, migrating to a new platform is not just a good idea, but an urgent imperative.
Now we move on to the next question. Beware, there’s a catch.
What are the advantages and disadvantages of replatforming? The short answer is it depends. The long answer is we’ll need to ask more questions.
As we said earlier, apart from very obvious scenarios, like replatforming from an inefficient, outdated, expensive legacy systems to a modern, flexible eCommerce solution with lower costs, it’s impossible to define the pros and cons of replatforming without asking other questions first, such as where you are now and why you need to walk out that door. Or without considering what led you to choose the platform in the first place and what changed since then. Why aren’t things working (anymore)? Did they change? Did you?
Every platform has a reason people loved it once. And every platform has a reason people leave it eventually. Here’s what we see, grouped by the platforms our clients most often migrate from.
If you want a fully customizable solution that gives you total control over both design and functionality, if you can count on an advanced technical team to implement those customizations, and if “money is not a problem”, there aren’t many reasons for you to consider migrating from PrestaShop.
Businesses that initially choose PrestaShop are usually drawn to its open-source nature and the promise of complete customization. Unlimited flexibility and control sound great, but come at a significant cost — in complexity, hidden expenses, and ongoing maintenance challenges.
It’s a bit of a catch-22: using the flexibility of open source means increasing complexity, which in turn requires extensive resources, higher development costs, and longer implementation times. The ability to add functionality is good. The burden of never knowing what might break when you add it is not.
So maybe you don’t need to edit the source code to get customization. You can migrate to a platform with the most commonly needed core functionality baked in, and the flexibility to scale the platform when specific needs arise. Here’s our suggestion, compared to PrestaShop.
The only worse thing than high costs is unclear costs. Calculating all expenses accurately with PrestaShop can be tricky — hosting, technical support, maintenance, development costs, and additional extensions all add up. If you invested substantial development resources on the initial build, and then realized that even minor updates require dev resources to implement, and that the more you customize the harder it becomes to manage versions and patches and stay on top of things, you know exactly what we are talking about.
PrestaShop can become cumbersome to manage over time. Minor updates break customizations. Updates requiring additional developer resources. Replatforming from PrestaShop doesn’t mean giving up freedom. On the contrary, it brings different kinds of freedom, that you can actually enjoy.
For example, freedom from the technical complexities and unexpected costs associated with open source solutions. Also, you won’t spend valuable resources making — or worrying about — minor tweaks, installing patches, updates, putting out fires, just to keep the engines running, so you’ll gain the freedom to choose what to focus on and where to allocate your time and talent.
If you’re using WooCommerce, the primary plugin used to power ecommerce stores on WordPress, and considering it leaving behind, you are most likely worried about two things: scalability and cost.
WooCommerce is not modular or built to scale, so large or growing brands that start on WooCommerce eventually have to replatform. The frontend and backend share resources, which makes it hard to scale without slowing down the live store, an issue you will not have with a SaaS solution. This also means daily activities of running your store (such as processing orders or running reports can affect the uptime & speed of your live store, which is also not great for your conversion, SEO, and brand in general.
And then there’s cost, a potentially significant issue, potentially being the operative word because the main issue with cost in WooCommerce is that it’s unclear. Although the plugin is technically free, total cost of ownership is not easy to sort out because of app and developer costs. Also, merchants are responsible for hosting and security/PCI plugins, regular maintenance & security patches. This could mean thousands of dollars in fines, in case of PCI compliance violations, as well as damage to your brand reputation.
WooCommerce stores also lean heavily on apps and plugins (some free, many with installation fees plus annual paid updates) for core functionality, which stacks on top of developer costs. Setup can be time-consuming and extensive. Managing updates can be costly.
What you gain replatforming from WooCommerce. Freedom from the technical burdens of self-hosted solutions, so you can focus on your business’s core operations. Access to more native features for shipping, sales tax, payments, product options, and omnichannel sales — less required customization, lower developer costs. Better and easier options to do what you’re already doing, and to start doing what you want to do.
What’s not to like? Well, replatforming is not trivial.
Migrating to a more efficient and scalable solution may present challenges in data migration and require some adaptations. Adapting customizations or themes to the new framework, which means evaluating whether to replicate those customizations or implement alternatives is one. Also, users and administrators will need to adapt to the new platform, which means you will have to factor the training and learning curve associated with the migration.
None of these are significant drawbacks if you consider, as you should, an eCommerce solution with solid training and onboarding processes, and enlist the support of an experienced agency to help with the migration. Don’t try this without adult supervision.
Adobe Commerce (formerly Magento Commerce) is enterprise-grade. Robust, flexible, B2B-capable at core, with a huge extension ecosystem. For enterprise operations with serious technical depth, complex catalogs, multi-brand/multi-region setups, and a roadmap that demands full architectural control — Magento can be the right answer.
But “can be” and “is” are different things. And a lot of the merchants who landed on Magento didn’t need that much platform. They needed what someone told them Magento would give them.
When you stay. If you have an internal team (or a retained agency) that owns the platform day-to-day, if your yearly TCO sits comfortably inside your P&L, if upgrade projects don’t feel like hostage negotiations, and if the flexibility you’re paying for is flexibility you’re actually using — stay. Magento was built for you.
When you leave. The most common reasons we see teams migrate away from Magento 2:
What you gain replatforming from Magento. Depending on where you go, lower TCO, faster development cycles, easier upgrades (SaaS removes the upgrade project altogether), and a team that spends less time on platform maintenance and more on commerce.
This is a conversation we have a lot. We’ve run the Magento-to-BigCommerce migration enough times to have a pattern for it. If your Magento build is starting to cost more than it returns, let’s talk.
It could mean freedom from the technical complexities and unexpected costs associated with open source solutions. Or freedom from spending valuable resources on minor tweaks, patches, and putting out fires just to keep the engines running. Or the freedom to choose what to focus on and where to allocate your time and your team’s talent. Replatforming can also give you the freedom to make financial decisions with a clearer understanding of your total cost of ownership. Freedom from surprise costs. Always a good thing.
It can be a chance to future-proof the business, reduce costs, and regain velocity. Whatever platform you move to, choose one with solid training, good onboarding, and solid support. And partner with an experienced team because the difference between a migration that goes well and one that goes catastrophically is usually experience, not price.
If you’re at this point, our B2B eCommerce Guide covers the architecture decisions that shape where you should go next.
Every replatforming we’ve done started with someone saying “this is fine” for six months too long. The cost of that delay usually dwarfs the cost of the migration itself. If you’re reading this guide and recognizing yourself in one of the three scenarios, that’s the signal.
