It provides developers with powerful tools to build dashboards, forms, tables, and management systems quickly and efficiently. As new versions of Filament are released, upgrading becomes important to gain access to improved performance, enhanced security, bug fixes, and new features.

This article explains the process of upgrading Filament versions in a Laravel project, common challenges developers face, and best practices to ensure a smooth transition.

 1.1 Scope of This Guide

This guide primarily focuses on upgrading Filament 3.x projects to Filament 4.x. While many of the preparation, testing, and deployment practices apply to any Filament upgrade, specific migration steps, architectural changes, and compatibility considerations discussed throughout this article are based on the Filament 3 → Filament 4 upgrade path.

If you are upgrading from Filament 2.x, review the official Filament upgrade documentation and complete any intermediate upgrade requirements before proceeding.

2. Why upgrade Filament?

Upgrading Filament offers several advantages:

• Improved performance and optimization
• Better compatibility with newer Laravel versions
• Access to new UI components and features
• Security patches and bug fixes
• Cleaner APIs and developer experience
• Long-term maintenance support

Regular upgrades help keep applications stable, secure, and easier to maintain.

3. Preparing for the upgrade

Major Filament upgrades can introduce breaking changes, dependency conflicts, and compatibility issues. Proper planning helps reduce risk and downtime. Therefore, before initiating the upgrade process, thorough preparation and planning are essential. Establishing a structured approach and following the correct upgrade sequence helps minimize risks, reduce downtime, maintain system stability, and ensure a smoother transition throughout the implementation process.

The following steps provide a structured approach to upgrading Filament safely and efficiently.

3.1. Backup the Project

Always create a complete backup of the following before starting the upgrade process:

• Project files
• Database
• Environment and configuration files

Maintaining proper backups ensures that the project can be safely restored or rolled back in case of unexpected issues, failures, or compatibility problems during the upgrade.

Create a new branch from the master branch to isolate upgrade-related changes and maintain version control stability:

git checkout -b filament-upgrade

Pull the latest changes from the master branch to ensure the upgrade process is performed on the most up-to-date codebase:

git pull origin master

3.2. Commit Current Code Before Upgrading 

Before modifying any dependencies, create a Git snapshot of the current application state: 

git add . 

git commit -m "Pre-Filament upgrade snapshot" 

This provides a reliable rollback point if the upgrade introduces unexpected issues.

3.3. Check Current Versions

Document the current versions of PHP, Laravel, Filament, Livewire, and installed plugins before starting the upgrade. This helps identify compatibility requirements, avoid version conflicts, and ensure a smoother transition during the upgrade.

Ex-

PHP

php -v

Laravel

php artisan --version

Filament

composer show filament/filament

Livewire

composer show livewire/livewire

Confirm that all existing versions are compatible with the targeted upgrade path and supported package ecosystem before proceeding further.

3.4. Pre-Upgrade Compatibility Review

Before upgrading, thoroughly review all compatibility requirements for the target Filament version.

Review the following resources:

• Official Filament upgrade documentation
• Release notes
• Changelogs
• Laravel compatibility requirements
• Livewire compatibility requirements

Many breaking changes and migration recommendations are documented in release notes rather than the upgrade guide itself.

Additionally, verify that all third-party plugins support the target Filament version before proceeding.

Common examples include:

• Filament Shield
• Filament Breezy
• Filament Spatie Media Library
• Custom in-house plugins

Plugin incompatibilities are one of the most common causes of upgrade failures. Update, replace, or temporarily disable unsupported plugins before beginning the upgrade process.

4. Updating Composer dependencies

The upgrade process mainly starts with updating Composer packages.

4.1 Example Composer Update:

composer require filament/filament:^4 -W

The -W flag allows Composer to update dependent packages automatically

After upgrading check-

PHP

php -v

Laravel

php artisan –version

Filament

composer show filament/filament

Livewire

composer show livewire/livewire

New Filament versions may introduce updated assets, configuration changes, database migrations, or additional frontend dependencies that are required for proper functionality and compatibility.

Run the following command to upgrade Filament and publish the necessary assets and updates:

php artisan filament:upgrade

NOTE- Verify the command exists for your target Filament version by consulting the official upgrade guide.

Run database migrations after the upgrade to apply schema changes required by the new Filament version

php artisan migrate

This ensures that all database schemas, tables, and system configurations remain compatible with the upgraded Filament version.

If new frontend or NPM dependencies are introduced during the upgrade process, install the required packages using:

npm install

Then rebuild the frontend assets to ensure all updated packages and compiled resources are properly generated:

npm run build

Running these commands helps prevent common asset compilation issues, missing dependency errors, frontend inconsistencies, and version-related build failures after the upgrade.

5. Clear Cache and Verify Dependencies

After completing the upgrade, clear all Laravel caches to prevent issues caused by stale configurations, cached routes, compiled views, or outdated optimization files.

php artisan optimize:clear

In most cases, php artisan optimize:clear is sufficient. Run individual cache clearing commands only when troubleshooting specific issues.

php artisan config:clear

php artisan view:clear

php artisan route:clear

This helps ensure that the application loads the latest configurations and updated resources correctly after the upgrade.

6. Optional Project Cleanup Tasks

Check for unused or unnecessary dependencies in the package.json file to keep the frontend environment clean and optimized.

npx -y depcheck

This scans the project and identifies unused packages, missing dependencies, and potential cleanup opportunities.

To install a specific package and automatically add it to package.json, use a cmd like:

npm install @tailwindcss/vite --save

To install all dependencies defined in the package.json file:

npm install

After installing or updating dependencies, rebuild the frontend assets:

npm run build

This generates updated production build files and helps avoid frontend compilation or asset-related issues.

7. Verify and Clean Composer Dependencies

Check for unused or unnecessary dependencies in the composer.json file to maintain a clean and optimized backend environment.

Install the dependency analyzer:

composer require –dev shipmonk/composer-dependency-analyser

Run the dependency scan:

php composer-dependency-analyser

This helps identify unused Composer packages and dependency inconsistencies within the project.

To remove unused packages:

composer remove <package-name>

Regular dependency cleanup improves maintainability, reduces package conflicts, and helps keep the application lightweight and stable.

8. Filament-Specific Upgrade Considerations
