✨ The Augmented Approach: How It Works
Our AI Expertise
When years of Symfony expertise meets artificial intelligence.
Assisted analysis & transformation
Our AI tools map your codebase, isolate deprecations, and automate repetitive code rewrites according to official Symfony standards.
Guardrails & test automation
Every step of the migration is backed by automated test suites to enforce strict non-regression and validate the behavior of the refactored code.
Expert review & architecture sign-off
A certified Symfony consultant takes over for complex architectural choices, handles edge cases, and manually reviews the final codebase before deployment.
Two Approaches, the Same High Standards
No matter if you choose our AI-assisted workflow or our traditional method, your upgrade is delivered under a fixed-price contract by certified experts. Choose the approach that best fits your code governance policies.

Frequently Asked Questions (FAQ)
- How much does a Symfony upgrade cost?
-
It depends on the version upgrade you choose. All our version upgrade services (AI or traditional) are delivered under fixed-price contracts. The exact scope and pricing are calculated following our free diagnostic evaluation, giving you budget predictability before writing a single line of code.
- What are the actual time savings with the AI approach?
-
On average, our internal tools reduce overall project delivery timelines by 50%. The exact timeline depends on your codebase size and how many major versions your application needs to cross. This will be described in your diagnostic report.
- My codebase is highly confidential. Can I opt out of AI processing?
-
Absolutely. We offer our "Standard" approach, which is 100% human-driven. No LLMs or third-party automated processing tools will ever touch your source code. You retain all SensioLabs guarantees (certified experts, thorough testing, fixed pricing), with standard human-paced delivery timelines.
- How do you guarantee that the AI version upgrade won't break my app?
-
We enforce a strict, deterministic testing methodology. Automated test suites validate every automated refactoring phase to prevent regressions. On top of that, a certified Symfony engineer performs a final manual architecture and code review.
- Is AI reliable enough to refactor core business logic?
-
AI is used strictly as a structural and syntax accelerator (handling deprecated method signatures, namespace updates, etc.). It makes no autonomous architectural choices. A SensioLabs consultant drives every automated tool and signs off on every commit.
- Which Symfony versions do you support?
-
We support all upgrade paths (e.g., migrating from Symfony 2.8, 4.4 or 5.4 to 6.4, 7.x, or 8.x), including codebases running on legacy versions that have been unsupported for years.
