[White Paper] Migration from legacy to Symfony

As the creator of Symfony, SensioLabs has been advocating in favor of PHP for many years. To keep up with the breathless pace of innovation in PHP, you should implement a migration to Symfony, a modern, robust framework. That is the story SensioLabs and Smile tell you in their new joint white paper.


SensioLabs and Smile released a new joint white paper

Before writing this white paper, SensioLabs and Smile noticed that a lot of old unmaintained frameworks are still active. Starting from this fact, they have been both working on a joint white paper explaining why you should migrate to Symfony.

For several years, Smile and SensioLabs have shared a common passion for innovation in Open-Source. Smile is the European market leader in digital Open-Source, and SensioLabs is the creator of the Open-Source framework Symfony. The two companies established a strategic alliance in 2019 to scale their expertise in PHP and Symfony for the benefit of their respective clients.

The two companies are complementary. Smile builds digital projects, and SensioLabs brings expertise in PHP and Symfony. Because code legacy and unmaintained frameworks are detrimental to PHP and digital projects, SensioLabs and Smile decided to address this decisive issue together. This white paper is a practical approach to help businesses and non-profit organizations grow and stay relevant in the future years. The good news is that you can reach this objective, thanks to Symfony.

You need a high-performance framework

First of all, the white paper looks into the PHP landscape in 2021. It explains why you should use a framework to develop your application in PHP. PHP now fits a new tech environment: Cloud computing, online customer experience, IoT, cybersecurity, etc. To deal with these critical innovations it has become essential that your application relies on a modern framework.

What are the signs showing that you need to switch to a modern framework? SensioLabs and Smile have identified 10 signs your code is rot from their extensive experience in web development. They also explain the most important criteria to choose a framework like fame, documentation, or philosophy. After reading of this white paper, you can assess if you need to migrate and what aspects if your project you should explore before migrating.


A migration to Symfony is a safe decision

You have realized that you should migrate to a new PHP framework? Symfony is probably one of the best options you have for your app. Symfony relies on a set of principles, making it powerful yet simple. These principles include Open-Source, interoperability, easy access, and pragmatism.

The white paper also tells why a Symfony migration is a safe choice. Thanks to backward compatibility, a predictable release cycle, and the continuous upgrade path, Symfony is easy to manage. Rules are clearly established from the beginning, so you won’t get nasty surprises in your journey.


In addition to this, Symfony comes with a comprehensive ecosystem. Symfony has a global community with thousands of developers. Many high-performance tools help your Symfony project: Blackfire on performance, SymfonyInsight to audit your code, and SymfonyCloud to automate the deployment of your Symfony infrastructure.

As the creator of Symfony, the company SensioLabs can support your migration to Symfony. To suit your migration needs, SensioLabs can organize a Migration Workshop, a Progressive Migration, coaches, and train your development team.
