Sylius 2 – Time to Upgrade. Launching an Educational Hub for Engineering Teams

Increasingly, engineering teams maintaining e-commerce platforms based on Sylius 1.x are reaching a critical point where planning a migration to the next version is no longer optional. With the fast-approaching End of Life (EOL) for older tech stacks and the rapid evolution of the Symfony-based framework, upgrading to Sylius 2 has become a cornerstone of many organizations' technological roadmaps. To address this, Commerce Weavers has launched a dedicated Educational Hub – a resource center where we publish in-depth materials designed to help developers prepare for and execute migrations in a structured, predictable manner.

Why should you consider the Sylius 2 upgrade now?

Sylius 2 introduces a complete modernization of the e-commerce platform’s technology stack. Migrating allows your system to transition to:

  • Symfony 7,

  • API Platform 4,

  • modern frontend powered by Bootstrap 5 and Symfony UX,

  • Symfony Workflow replacing Winzou State Machine.

These changes directly impact long-term maintainability, architecture stability and development velocity.

Remaining on Sylius 1.x increases technical debt accumulation. As legacy versions approach End of Life (EOL), security risks grow and feature delivery slows down significantly.

The longer the migration is delayed, the larger the gap between your codebase and the current ecosystem standards.

Expert Insight: Sylius 2 Upgrade Checklist

Why can migrating from Sylius 1 to 2 be challenging?

In many projects, the upgrade appears straightforward until the engineering team begins to analyze the granular implementation details. The most significant hurdles typically emerge in two critical areas:

Hidden Project Complexity. The official changelog is only half the battle. The real challenge lies in the degree of project customization. In many established stores, business logic is deeply coupled with legacy state machine mechanisms, the frontend layer, or older API versions – all of which have undergone radical architectural shifts in Sylius 2.

Plugin Compatibility and Ecosystem Alignment. The Sylius ecosystem comprises hundreds of plugins published on Packagist. While many have already transitioned to support Sylius 2, enterprise-grade projects often rely on proprietary extensions or legacy third–party integrations.

What does Sylius 2 change at the technological level?

Migration involves a comprehensive upgrade of the platform’s core architectural components.

Sylius 2 Migration Hub – A Comprehensive Knowledge Base for Engineering Teams

To support engineering teams, we are launching a dedicated Educational Hub focused on Sylius 2 migration.

The hub will evolve iteratively and include:

1. Technical readiness checklist

A structured checklist to assess migration readiness.

Covers:

  • state machine customizations,

  • plugin dependencies,

  • frontend architecture changes,

  • payment integrations,

  • API surface analysis.

2. Migration effort calculator

A diagnostic tool designed to estimate migration complexity based on specific project parameters. It calculates the necessary engineering resources by analyzing variables such as the number of installed plugins, custom domain entities, and the depth of external system integrations.

3. AI-assisted migration workflow

An experimental framework leveraging AI tools to accelerate the code migration process. This workflow assists in identifying potential architectural bottlenecks and automates repetitive refactoring tasks.

4. Plugin compatibility radar

A dedicated tracker monitoring the compatibility status of the most widely used Sylius extensions. This includes solutions from key ecosystem contributors such as BitBag, Setono, MonsieurBiz, and Synolia.

The Hub will also feature additional educational resources focused on Sylius 2 architecture, long-term upgrade planning, and migration best practices.

Sylius 2 represents the most significant architectural evolution in the platform’s ecosystem in years. Consequently, a well-structured migration strategy is mission–critical for ensuring the stability and future scalability of your e-commerce system.

FAQ - Sylius 2 upgrade

What does the migration to Sylius 2 involve?

Migration means upgrading from Sylius 1.x to a stack based on Symfony 7, API Platform 4 and a modern frontend architecture. In enterprise cases, it also includes auditing custom extensions and integrations.

Is the migration to Sylius 2 mandatory?

Long-term yes. Sylius 1.x depends on legacy components that are reaching End of Life (EOL). Migration ensures compatibility, security and maintainability.

How complex is the upgrade from Sylius 1 to Sylius 2?

It depends on customization level. Simple projects are straightforward. Enterprise systems require deep analysis of plugins, integrations and workflow logic.

Main effort areas:

  • frontend refactoring,

  • integration updates,

  • API Platform 4 upgrade.

When is the best time to plan the Sylius 2 migration?

During low business load periods, outside peak sales seasons. Start with a technical audit and dependency analysis.

Are all plugins compatible with Sylius 2?

Not yet. Many are ready, but enterprise systems require individual verification. That’s why a compatibility radar is part of the Migration Hub.
