PrestaShop Sylius Migrator

Every platform has its best use. PrestaShop has helped thousands of merchants get online quickly, build their first catalogue, and start selling - and it does that job well. But at some point, most growing businesses hit the same wall, where the platform that got them started can't keep up with where they're going.

Migration tends to come up when the codebase gets harder to maintain, when performance drops are much more visible, or when a new business requirement turns into a six-week development project that probably should have taken two. At that point, moving platforms isn't a drastic move but rather a logical next step.

Done right, migration doesn't have to be the disruptive project most online stores fear. With clear goals, a well-defined scope, and proper testing in place, it becomes a predictable process that minimizes downtime and actually sets the platform up for faster growth going forward.

Keeping this in mind, today’s article will focus on why merchants migrate from PrestaShop to Sylius, when it makes sense to do so, and how the actual data migration works, including the tool BitBag offers specifically to make the process less painful.

Why migrate from PrestaShop to Sylius

The first thing worth saying: PrestaShop and Sylius aren't really competitors. They serve different stages of a business's lifecycle, and thinking of them as rivals misses the point.

PrestaShop is genuinely great for what it's designed for. Low barrier to entry, quick setup, a large module marketplace, and a community that's been around since 2007. If you're a small or mid-size merchant who needs to launch fast without a dedicated development team, PrestaShop delivers. It handles the fundamentals well and gets you selling without unnecessary complexity.

The problem tends to build up gradually. A module here, a workaround there - and then one day the team is spending more time maintaining the platform than building on it. Performance drops as the catalogue scales, integrations get harder to keep in sync, and requirements like B2B pricing or multi-store management start pushing up against the boundaries of what PrestaShop was designed to handle.

That's where Sylius fits in. It's a flexible eCommerce platform built on Symfony, designed from the ground up to be customized. There's no fighting the architecture to implement business-specific logic - the whole thing is built around the assumption that your requirements will be different from everyone else's. Complex pricing, custom workflows, B2B at scale, deep integrations - that's not the hard part in Sylius. That's the point.

The takeaway here isn't that one platform is better than the other. It's that these two tools are built for different problems. PrestaShop is where a lot of great eCommerce businesses start. Sylius is where the ones with more complex requirements often end up. Migration isn't a statement that the first choice was wrong, but rather a sign that the business has grown.

When to migrate from PrestaShop to Sylius

Knowing “why” to migrate is one thing, but knowing “when” is where most businesses get stuck. The timing depends on a mix of business signals, technical constraints, and growth plans that look different for every store. Learn more in the newest Sylius article devoted to the topic.

How to migrate from PrestaShop to Sylius

Migrations have a reputation for being messy (and sometimes they are), especially when done manually. Moving large product catalogues, customer records, and order histories by hand is slow, error-prone, and hard to validate.

To make the process more manageable for clients planning the switch, we built the PrestaShop Sylius Migration Tool, our in-house solution designed specifically for our clients. It brings structure to the whole process, reduces risk, and ensures the store keeps running throughout the transfer. The goal is simple: make moving to Sylius a clear step forward, not a source of stress and uncertainty.

What you can migrate

The Migrator covers the three core data areas that matter most in any platform switch:

Orders: order numbers, purchased products, payment details, shipping information, and statuses
Customer data: demographic, behavioural, and personal data
Product catalog: products and variants, categories, attributes, descriptions, pricing, stock levels, and media

<div class="rtb-text-box is-blue-50">Of course, data is only one piece of the puzzle - integrations, design, and the overall user experience of the new store all need attention too.</div>

The migration process

The export side lives in the PrestaShop admin panel. The store administrator selects which data to export (orders, customers, product catalog, or any combination) and starts the process. From there, everything runs in the background. The store keeps operating normally while the exporter works through the data in batches, and a progress indicator in the panel shows how far along the export is. For large catalogues, this matters - you're not sitting blind waiting for something to finish.

Our migrator allows you to run a test import. This allows us to catch potential inconsistencies in advance, such as duplicate order numbers, SKU conflicts, or existing customer email addresses, so you can resolve them before they become a problem. This small step removes a lot of uncertainty from the entire process.

Wrapping up

Switching platforms is a major step, but it doesn't have to be an uncertain one. With the right preparation and tooling in place, a PrestaShop to Sylius migration can be a clean, well-managed process, one that sets the business up for what comes next rather than creating new problems to solve.
