5 Laravel Upgrade Pitfalls Tha ...

A Laravel upgrade that was supposed to take a sprint just burned three weeks. The tests pass locally, staging is broken in ways the upgrade guide never mentioned, and two critical packages don’t have compatible releases yet. Sound familiar?

We’ve worked with development teams running Laravel apps from v6 through v10. The pattern is remarkably consistent: the framework upgrade itself isn’t what stalls the project. It’s the assumptions made before anyone opens composer.json.

Five pitfalls account for most of that lost time.

1. Treating the Upgrade Guide as a Complete Checklist

Laravel’s official upgrade guides are thorough. They cover breaking changes, deprecated methods, and configuration shifts between versions. What they don’t cover is your application.

The guides assume a clean, idiomatic Laravel codebase. Production apps rarely are. They carry custom service providers built three versions ago, middleware chains that reference deprecated interfaces, Blade templates relying on helpers that quietly vanished two releases back. A team follows the upgrade guide line by line, finishes every item, runs the suite — and hits a wall of failures that no documentation prepared them for.

What works instead: Before touching Composer, run a dependency audit against your actual codebase. Map every service provider, middleware, custom Artisan command, and third-party package to its version compatibility. The upgrade guide tells you what Laravel changed. Your audit tells you what those changes break in your application.

2. Skipping Versions and Expecting a Clean Jump

Laravel’s release cadence means a team on v6 is now four major versions behind. Jumping straight to the latest release is tempting. It almost never works cleanly.

Each major version introduces breaking changes that compound across releases. A method deprecated in v7 gets removed in v8. A config key renamed in v9 triggers silent failures in v10. Skip the intermediate versions, and you skip the incremental migration paths that would have caught these breaks one at a time.

The compounding effect is what makes multi-version jumps unpredictable. A change that takes five minutes in an incremental upgrade can take five hours to debug when you’re crossing three versions at once, because the error messages reference the current state — not the version where the break actually originated.

The fix is counterintuitive: step through each major version sequentially, even if you don’t deploy the intermediate versions to production. Run your test suite at each step. This isolates breaking changes to the version that introduced them, which makes debugging dramatically faster.

3. Underestimating Third-Party Package Drift

The average Laravel application pulls in 40 to 80 Composer packages. Each one has its own Laravel version compatibility matrix, its own deprecation timeline, and its own maintainer situation.

This is where the upgrade grinds to a halt. Your app depends on a package that hasn’t shipped a compatible release for the target Laravel version. Sometimes the fix is a one-line change. Sometimes the package is abandoned and you need a replacement. Sometimes the package technically supports the new version but introduces its own breaking changes that cascade through your codebase.

Teams that don’t audit package compatibility before starting the upgrade discover these problems mid-migration, when rolling back is expensive and pushing forward requires unplanned refactoring.

Do the audit first. Generate a full package compatibility matrix before starting the upgrade. For each dependency, check whether a compatible version exists for your target Laravel release. Flag any package that’s unmaintained (no commits in 12+ months), has open compatibility issues, or requires a major version bump of its own. Resolve these blockers before you touch composer.json.

4. Running Without Adequate Test Coverage

This one is uncomfortable because it’s rarely the upgrade’s fault. Teams with strong test suites upgrade Laravel in days. Teams without them spend weeks debugging in production.

The problem isn’t just missing tests — it’s missing the right tests. Unit tests that mock everything won’t catch a broken service provider binding. Integration tests that skip HTTP layer won’t catch middleware changes. Feature tests that don’t exercise Blade rendering won’t catch template-level deprecation.

Without coverage that exercises the actual integration points between your code and the framework, you’re relying on manual QA to catch breaking changes. Manual QA at the framework layer is slow, inconsistent, and misses edge cases.

What works instead: Before starting the upgrade, identify your application’s framework integration points — routes, middleware, service providers, Eloquent observers, event listeners, Blade directives, queue jobs. Write targeted tests for any integration point that lacks coverage. This investment pays for itself across every future upgrade, not just this one.

5. No Rollback Strategy Beyond “Revert the Branch”

Git makes it easy to revert code changes. It doesn’t revert database migrations, cache schemas, config file changes, or queue job formats. Teams that treat git revert as their rollback plan discover this when a partially-applied upgrade breaks production and reverting the code doesn’t fix the state.

The most expensive upgrade failures we’ve seen weren’t caused by bad code changes. They were caused by database migrations that ran successfully in the new version but created schema states that the old version couldn’t read.

Rollback has to happen at the infrastructure level, not just the code level. Snapshot your database before migrating. Tag your deployment artifact. If you’re running queues, drain them before upgrading. Document the exact sequence to restore both code and state, and test that procedure in staging before you touch production.

The Common Thread

Every one of these pitfalls traces back to the same gap: starting a Laravel version migration before mapping what your application actually depends on. The framework’s breaking changes are documented. Your application’s tangled relationship to the framework — the implicit bindings, the quietly-patched packages, the hand-rolled middleware from 2019 — usually isn’t.

And that gap widens with every version you fall behind. A team running Laravel 6 isn’t facing one upgrade. They’re facing four sequential modernization steps, each with its own compatibility surface. Auditing all of that by hand, for every major release, is exactly the kind of tedious and error-prone work that’s better handled programmatically.

Laravel Ascend is an open-source upgrade tool built for this problem. It automates dependency analysis, version-stepping, and compatibility checking — turning a multi-week Laravel migration into a predictable, repeatable process. If your team is staring down a multi-version jump, it’s worth reviewing before you start pulling threads manually.
