How to migrate an eCommerce store: step-by-step process, checklist, and best practices

Why migrate your online store?

The decision to migrate a store usually comes from specific business or technology problems. The current platform may be too slow, difficult to develop, expensive to maintain, or limited when it comes to integrations with external systems.

Store owners also decide to migrate when they want to grow B2B sales, enter new markets, improve UX, add new payment methods, automate order handling, or connect the store with ERP, PIM, WMS, OMS, marketplaces, or marketing automation tools.

A well-executed store migration can bring many benefits:

• better store performance,
• easier product and order management,
• greater flexibility in developing new features,
• simpler integration with external systems,
• a better user experience,
• more control over SEO,
• a more stable foundation for scaling sales.

Not migrating can also create risk. An old platform that no longer keeps up with business growth often limits sales more than it may seem at first glance. Problems may appear in performance, security, large product catalogue management, data handling, checkout development, or integrations.

In practice, store migration should not be treated only as moving products from one platform to another. It is a good moment to analyse the entire eCommerce ecosystem and decide which processes should be organised, automated, or redesigned from scratch.

Migration planning – key steps

A successful store migration starts with a plan. Without one, it is easy to enter a project that grows in scope over time, generates additional costs, and causes problems during the final launch.

The first step is to analyse business needs. You need to answer why the company wants to change platform and what goals the new store should achieve. Is the priority performance, SEO, B2B development, international sales, process automation, integrations, UX, or greater control over technology development?

The second step is choosing the platform. For medium and large stores, a PrestaShop migration plan is often considered, especially when the company needs a flexible open-source solution, strong development potential, and control over integrations.

The next stage is defining the scope of work. You need to decide exactly what will be moved, what will be rebuilt, and what should not be transferred to the new store. Not every module, feature, or process from the old platform should be copied one to one.

An eCommerce migration checklist is very useful during planning. It may include, among other things:

• product data analysis,
• category and store structure audit,
• review of order history and customer data,
• URL and SEO analysis,
• integration verification,
• review of existing modules and features,
• backup preparation,
• test plan,
• migration schedule,
• final store switch-over plan.

A detailed schedule is important because store migration touches many areas at the same time: technology, SEO, sales, logistics, payments, customer service, and analytics. Each of these areas should have its own tasks, responsible people, and deadlines.

A well-prepared PrestaShop migration plan should also include risks. It is worth defining in advance what may go wrong, who makes decisions in emergency situations, and how quickly the previous version of the store can be restored if a serious problem occurs.

Technical preparation for migration

Technical preparation is a stage that should not be shortened. This is where you can detect problems that, after launch, could cause serious disruptions to sales.

The foundation is data backup. Before migration, you need to secure the database, store files, product images, customer data, order history, payment and delivery settings, module configuration, SEO data, and integration documentation. The backup should not only be created, but also tested in a staging environment.

Another element is compatibility analysis. You need to check whether the new environment meets the technical requirements of the selected platform, whether modules have their equivalents, whether integrations can be recreated or rebuilt, and whether the hosting can handle the planned traffic, product volume, and synchronisation frequency.

For a project based on a PrestaShop migration plan, it is worth checking, among other things:

• the PHP version compatible with the selected PrestaShop version,
• the database version,
• server configuration,
• SSL certificate,
• cron jobs,
• PHP limits,
• required extensions,
• cache and performance,
• the staging environment.

The test environment is very important. Store migration should not be carried out directly on production. First, a test version should be prepared, where data can be safely imported, modules configured, integrations checked, checkout tested, and errors detected.

Tools such as Google Search Console, Screaming Frog, Google Analytics 4, Google Tag Manager, performance monitoring systems, backup tools, and page speed testing tools can help with technical preparation. In larger projects, API documentation and a precise description of data flows between the store and external systems are also important.

At this stage, it is also worth expanding your own eCommerce migration checklist with technical tasks. It should cover not only backup and data import, but also server configuration, integration tests, performance tests, a redirect map, and an emergency plan.

Migration step by step

The stages of moving an online store should be carried out in an organised way. This makes it easier to control risks and respond faster when errors appear.

Step 1: Preparing the staging environment

The new store should be built in a staging environment. This is where the platform, modules, theme, integrations, and data import are configured. The test environment should reflect the future production environment as closely as possible.

Step 2: Exporting data from the old store

At this stage, products, categories, customers, orders, prices, images, attributes, variants, and other data needed in the new store are exported. It is worth checking data quality immediately and marking elements that need improvement.

Step 3: Importing data into the new platform

The first import should be a test import. It allows you to check whether data is mapped correctly, whether products have the correct prices, images, and variants, and whether categories have been properly recreated.

Step 4: Configuring store functions

Next, payment methods, delivery methods, taxes, currencies, languages, pricing rules, discounts, modules, and additional features are configured. This is an important stage because even a small configuration error can later affect orders.

Step 5: Configuring integrations

Connections with ERP, PIM, WMS, OMS, BaseLinker, marketplaces, courier systems, payment systems, invoicing, and marketing tools need to be checked. Integrations should be tested end to end, from placing an order to handling it in external systems.

Step 6: Preparing SEO

Store migration can affect visibility in Google, so you need to prepare a 301 redirect map, check URLs, meta titles, meta descriptions, headings, internal linking, the sitemap, and the robots.txt file.

Step 7: Testing before launch

Before the final switch-over, the entire store needs to be tested. The most important areas are: search, categories, product pages, cart, checkout, payments, delivery methods, transactional emails, invoices, order statuses, and the mobile version.

Step 8: Final store switch-over

It is best to plan this for a period with the lowest traffic. Before the switch-over, an up-to-date backup should be created and the team should be ready to monitor the store after launch. After the DNS change, the store should be observed for the first 24–72 hours.

eCommerce migration checklist as a control tool

A well-prepared eCommerce migration checklist helps make sure that none of these stages are skipped. It is worth treating it as a practical working tool for the technical team, SEO team, project manager, and people responsible for sales.

In practice, the stages of moving an online store should be divided into actions before migration, actions during migration, and actions after the launch of the new platform. This makes the whole process easier to control.

Checking store functionality after migration

Launching the new platform does not mean the work is over. The first days after migration are critical because this is when errors that were not detected earlier most often appear.

After migration, the entire purchase process needs to be checked. Users should be able to find a product, add it to the cart, choose a delivery method, pay, and receive the correct order confirmation without any issues. Tests should include different scenarios: guest checkout, purchase from a customer account, different payment methods, different delivery methods, products with variants, discount codes, and orders placed on mobile devices.

It is also worth running performance tests. The store should load category pages, product pages, the cart, and checkout quickly. It is especially important to check how the store performs under higher traffic, with a large number of products, and during intensive synchronisations.

Another area is UX. After migration, it is worth checking whether users understand the store structure, whether the menu is clear, whether the product page answers the most important questions, whether CTAs are clearly visible, and whether the checkout does not contain unnecessary obstacles.

To monitor the store after migration, you can use, among other things:

• Google Search Console,
• tools for monitoring 404 errors,
• Google Analytics 4,
• page speed analysis tools,
• Google Tag Manager,
• server monitoring systems,
• click maps and user session recordings,
• customer service reports.

Checking store functionality after migration should be an ongoing process. Even if the store works correctly on launch day, it is worth observing data over the following days and weeks to detect issues with indexing, conversion, integrations, or user behaviour.

A well-prepared PrestaShop migration plan should also include a post-launch monitoring schedule. This is important because some problems appear only when the store starts handling real customers, real orders, and ongoing synchronisations.

Best practices after migration

After migration is complete, it is worth implementing several best practices that help stabilise the store and make better use of the potential of the new platform.

• Monitor SEO after implementation – check indexing, 404 errors, 301 redirects, the sitemap, and the visibility of the most important pages.
• Analyse sales data – compare the number of orders, conversion rate, average order value, and revenue before and after migration.
• Observe how integrations work – pay attention to the synchronisation of stock levels, prices, orders, invoices, and delivery statuses.
• Check store performance – monitor page loading time, server load, and checkout performance.
• Test UX – analyse how users interact with the new store, where they click, where they abandon the cart, and which elements need improvement.
• Train the team – people managing the store should know how to handle products, orders, customers, promotions, and basic settings.
• Update documentation – after migration, it is worth documenting integrations, processes, access data, emergency procedures, and implementation rules.
• Plan further development – store migration is often the first step. After stabilisation, it is worth planning SEO and UX optimisation, automation, new features, and expansion into new markets.

The best results come from an approach where store migration does not end on the day the new platform is launched. It is a process that requires monitoring, analysis, and further optimisation.

A well-prepared PrestaShop migration plan should therefore cover not only moving the store itself, but also post-launch activities. This way, the new platform does not merely replace the previous solution, but genuinely supports the development of the entire eCommerce business.

It is also worth returning to the eCommerce migration checklist and adding post-implementation conclusions to it. This gives the company not only a new store, but also better documentation of processes and technology.

Summary

Store migration is a project that requires a good plan, technical preparation, and thorough testing. The key areas are not only the stages of moving an online store, but also risk analysis, data protection, SEO protection, integration testing, and post-launch monitoring.

A well-prepared eCommerce migration checklist helps organise the entire process and reduce the risk of errors. It makes it easier to check whether all areas have been covered: data, products, customers, orders, integrations, SEO, performance, UX, and the purchase process.

If you are planning to change platform, prepare a detailed PrestaShop migration plan and treat migration as an opportunity to organise the entire online sales ecosystem.

This way, the new store can not only work better technically, but also support sales, customer service, and further business growth more effectively.
