Laravel vs Symfony: an upgrade decision

Sources: Symfony releases and Laravel release notes, both read on 30 October 2026.

Laravel ships one major a year, each with 18 months of bug fixes and two years of security fixes. To stay supported, you upgrade at least every two years, and in practice about once a year if you want bug fixes too. Laravel’s stated aim is that a major upgrade should take a day or less, and recent upgrade guides are short.

Symfony ships a minor every six months and a major every two years. Teams that want stability sit on an LTS such as 7.4 and upgrade less often, for longer stretches of support, then do a larger move between LTS releases.

So Symfony’s LTS gives you a longer gap between mandatory moves, and that is a real advantage if you have few developers. But the gap only pays back over years. It doesn’t cover the cost of rewriting an application to get it.

Models, queries, queues, validation, views, authentication and tests are all written against the framework’s API. Laravel’s Eloquent and Symfony’s usual pairing with Doctrine ORM work differently, and that alone touches most business logic. Expect to treat a switch as a rebuild, with the same risks: lost edge cases, data migration, and months in which the business gets no new features.

For comparison, the largest upgrade we have published moved a system from PHP 5.6 and MySQL 5.0 to Laravel 13 in about eight months. That was already a rebuild in most senses, and it is the far end of the upgrade range, not the norm. A move from Laravel 11 or 12 is far smaller, as our 12 to 13 guide shows.

Upgrade Laravel when

• The application works and the business rules in it are valuable.
• Your developers know Laravel, or you can hire people who do.
• Your main worry is support dates. An upgrade solves that directly.

Consider Symfony when

• You are rebuilding anyway, and the code has little worth keeping.
• Your team already works in Symfony and would be slower in Laravel.
• Upgrading every year or two truly doesn’t fit, and a long LTS would.

If you are not sure which side you are on, the first question is whether an upgrade would cost as much as you fear. And if you are worried about what you have inherited, our Laravel rescue service starts by finding out.
