The Ultimate Guide to Ecommerce Replatforming: A Step-by-Step Approach [2024 Updated]

Ecommerce re-platforming is the process of migrating an online store from its current platform to a new website. It’s crucial because it allows online businesses to update their technology, improve user experiences, and stay competitive in the rapidly evolving ecommerce landscape.

Replatforming vs ReDesigning 

  • A platform is a foundational technology used to build your website’s backend infrastructure. 
  • Consider the CMS, the commerce engine, the translation engine, and other components you use to create, serve, and translate content and conduct sales.  
  • The UX, or front end, is the design. This is the user interface and the elements that allow your audience to interact with your application and render the site for them.

Replatforming can imply replacing a single component of your website’s backend tech stack or replacing all of them at once. It may or may not involve modifying your design. 

Redesigning involves altering the look and feel of your website and incorporating new UX components. If you do this by shifting to a new site without re-platforming your content, this is known as a “lift and shift.”

  • Previously, organizations often had to simultaneously undertake both processes, a practice referred to as “rip and replace.” This was common because they frequently coupled an outdated platform with an old design.
  •  However, we should note that there are valid reasons for doing one at a time. For example, perhaps your website has a fresh new look that you’d like to keep.
  • Alternatively, you may wish to reduce downtime and threat by implementing a phased rollout to replatform your site in sections.

How To Replatform Your Ecommerce Store

1. Create a list of requirements for re-platforming your business. 

  • This list should explain why you want to change your current system and what you hope the new system will do. 
  • It’s essential to involve everyone who cares about this – like the IT folks, marketing, sales, and even your customers.
  • Many companies think about changing their online platform when they have a bunch of problems to fix all at once. It could be because they’re growing, adding new ways to pay, expanding to new places, or selling new stuff. 
  • But here’s the thing: if switching to a new platform doesn’t make your website much better in terms of how it works, looks, and performs, then it might not be worth the trouble and the money.
  • So, before you start the whole process, it’s good to be clear about why you’re doing it and what you want to achieve. You should make sure the new platform you’re choosing can do what you need it to do.
  • And once you have this list, put the most important things at the top. It helps you make good decisions and get approval from the higher-ups and everyone else who needs to be on board. Knowing what each team needs is super important before you start this project.

Also, remember that re-platforming isn’t a quick fix. It’s a long-term investment. The platform you switch to should be able to keep up with changes in the market and grow your business as it gets bigger.

2. Choosing an ecommerce platform 

Here’s a brief list of ecommerce platforms to consider. 

  • In a re-platforming situation, most organizations are looking beyond basic options like Shopify, and WooCommerce.
  • Instead, they are exploring more advanced and versatile choices such as Magento (now known as Adobe Commerce), BigCommerce, Shopify Plus, or Kentico.
  • To make the right choice, you should match your requirements with these platforms and consider factors like cost, integrations, features, and the level of service they provide. 
  • It is a crucial step in your decision-making process, ensuring you thoroughly investigate the platform options before making any commitments.

3. Consider Cost and Timing. 

  • Note that any figures you receive before the above phase are just ballpark numbers. That’s why sharing your budget is a good idea. 
  • It can help you decide on the right supplier, platform, or features and save time reviewing proposals that don’t fit your budget.
  • Speaking of budgets, be aware that additional costs can pile up depending on your platform choice if you need third-party plugins. So, while planning, remember to account for this extra expense, as not all providers work the same way.
  • Also, while the final build costs will become clearer as you go along, your annual license fee from the chosen platform should remain consistent from the start.

4. Data Migration and SEO 

  • Data migration can be a major headache during re-platforming, and it’s a legitimate concern. Losing essential data, especially customer information, can be a disaster. 
  • Plus, the time and precision needed to move customer, product, and category data can vary widely from one business to another. 
  • If your current system isn’t causing major issues and you have limited resources to handle data migration, you might want to consider skipping re-platforming.
  • Another essential factor to think about is search engine optimization (SEO). When you replatform, your SEO rankings may take a hit. 
  • All the hard work your marketing and SEO teams put into driving traffic to your site could be lost during the migration. 
  • Be careful about redirecting all your pages, even if you can maintain your SEO rankings.
  • Remember, site errors are a top reason why users abandon shopping carts. So, if you’re worried about keeping your customers happy, you might want to think twice.
  • Make sure that you consider how data migration and SEO will affect your timeline if you decide to tackle this big task.
  • It’s essential to keep your marketing, operations, and SEO teams in the loop while planning to migrate customer data and replatform. 

Pro Tip: We suggest not re-platforming right before a big marketing campaign or during your busiest season, as it could hurt your sales and operational capacity.

5. To design or not to design

That’s the question you need to answer. Are you sticking with your current look or using this opportunity to give your brand a fresh new makeover? 

  • The initial design phase, with all the necessary approvals, can significantly extend your timeline and budget.
  • And if you’re going for a brand revamp and a shiny new interface for your ecommerce site, remember to factor in testing. 
  • You’ll need to do some tests to ensure your site works well on different browsers and devices. 
  • Plan for the tools you’ll need – this might involve ordering hardware, buying software to simulate different browsers and devices, or even hiring a development agency for this kind of work.

6. Seamless Integrations

  • Your current ecommerce setup probably has various extensions, plugins, and apps that handle essential tasks like subscription billing, marketing, CRM, and sales. 
  • It’s crucial to pick a new platform that can seamlessly fit into your existing system. This way, you don’t have to worry about performance issues or spending lots of time on development to make everything work together.
  • For example, if you’re happy with your current Sales application, the new platform you’re moving to can easily connect with it. 
  • If you’re thinking about changing some of your integrations, be sure that the data transfer process is secure and automated. That way, you can keep things running smoothly during the transition.

7. Testing is Crucial 

  • Testing is the crucial step of re-platforming. It’s often the neglected step in the process.
  • Testing isn’t the most exciting part, and it’s usually the first thing people want to skip. 
  • You need to thoroughly test your new platform, making sure it fits perfectly into your entire system. So, when it comes to testing, leave no stone unturned. 
  • Try out every piece of functionality and every system you can think of. Place orders, process returns, ship products, and even throw in some tricky scenarios and promotions. 
  • Find a way to test live transactions because testing in a controlled environment is one thing, but the real deal is quite different. 
  • Plan to interact with your live technology stack during testing.

8. The Go-Live Strategy

While the concept of launching your website might be exciting, practical considerations should govern your approach to going live. 

There are crucial aspects to be meticulously planned before the go-live date. Foremost among them is your transition plan: 

  • How will you discontinue the old site? 
  • Will you maintain the parallel operation of your previous platform? 
  • Are all your service providers informed of the impending change? 
  • Failure to communicate this effectively could lead to distressing midnight calls about website downtime.

After ensuring a well-structured plan, clear role assignments, and pressing the ‘Go’ button, it’s imperative to initiate SEO checks promptly. 

Verify that your URLs are redirecting correctly and extensively test the functionality of your newly implemented ecommerce platform by engaging in activities such as placing orders and exploring its full range of capabilities.

9. Post-Launch Support

The post-launch phase should not be overlooked, and it can be divided into three distinct sub-phases:

  • Go-Live Support (on launch day)
  • Immediate Post-Launch (the two weeks right after launch)
  • Long-Term Support

Ensure each phase has its distinct set of contact procedures and Service Level Agreements (SLAs). Maintain absolute clarity regarding whom to contact at various times of the day, the expected response times, and the definition of emergencies for all parties involved.

Keep in mind that your platform provider should handle hosting, upgrades, and security issues, while your development agency will take care of all other bugs or development-related matters.

Bonus: Remember To…

  • Remember to schedule training sessions for your customer service team. They’ll be the ones navigating the new system, and it’s crucial for them to be confident in using it before they begin managing actual customer orders.
  • It’s essential to define roles for project stages while structuring your project team.
  • The involvement level of your team member may vary depending on the project phase. So, as you outline your stakeholders, create an organizational structure that accommodates this variability. 
  • For instance, your agency might lead the design phase but have no involvement in the data migration process.

Ecommerce Migration: How is it Different from Ecommerce Replatforming 

  • Ecommerce migration involves moving an ecommerce website from one platform to another without modifying the website’s code or structure.
  • This process is straightforward when transitioning between similar platforms, but it can become complex when dealing with multiple platforms, referred to as “Rehost” in the 7 R’s framework.
  • Ecommerce re-platforming involves making significant changes to the core structure and code of the website.
  • While re-platforming may be more challenging, it offers greater opportunities for enhancements.
  • If you wish to add new functionality or features, re-platforming is a more suitable option than migration.
  • The choice between migration and re-platforming depends on your specific requirements.

When is the right time to replatform your site?

When deciding to replatform your website needs careful consideration of several factors.

  • Check out the age of your site and whether it requires any significant updates or changes. If it’s been around for a while without recent updates, replatforming could be a good decision to keep up with the current trends and technologies.
  • Consider the size of your target market and the platforms they prefer. Different user groups require different platforms and design templates.
  • If your site caters primarily to a specific demographic or platform, replatforming might be necessary to serve their needs better.

Do I need to hire a consultant? What are the risks of attempting to replatform on my own?

Replatforming an online store, whether small, medium, or large, is a complex process that necessitates technical expertise and experience. 

While it can be tempting to try a do-it-yourself approach to save money, doing so may result in numerous risks and challenges that can ultimately harm your business. Some of the risks of doing a replatform on your own are as follows:

  1. Lack of Required Technical Knowledge: Re-platforming an ecommerce website necessitates extensive knowledge of coding languages, API integrations, and data migration. You or your team may face significant roadblocks and delays if you or your team don’t have the necessary technical expertise.
  2. Downtime: Your ecommerce website may experience brief outages or downtime while it is being migrated. This can lead to revenue loss and a negative customer experience. An experienced development team can assist you in minimizing downtime and mitigating the impact of any issues that may arise.
  3. Loss of Data: Incorrectly transferring data during the migration process can jeopardize vital customer and business data, putting your business and reputation at serious risk.
  4. Security: When it comes to ecommerce, security is a major concern. You may be vulnerable to identity theft, hacking, and other cyber attacks if your website is not secure. A professional development team can assist you in ensuring that your website is secure and meets industry standards.
  5. Integration Difficulties: Integrating third-party systems and software can be difficult, and if done incorrectly, it can lead to problems with data sync, shipment fulfillment, and other critical business operations. An experienced development team can assist you in ensuring that your systems are properly integrated and running smoothly.
