Why Upgrading Strapi Matters
Upgrading Strapi is not just about accessing new features---it plays a pivotal role in the following areas:
1. Security Enhancements
Each update may include patches for vulnerabilities that could expose your application to risk. Staying current reduces the attack surface and ensures compliance with security best practices.
2. Performance Improvements
New releases often include optimizations for query speed, API response times, and build performance. Faster backend performance improves the total user experience.
3. New Features & Plugins
Major and minor Strapi updates introduce new core features, plugin improvements, and better customization capabilities.
4. Framework Compatibility
Strapi relies heavily on Node.js and modern JavaScript tooling. Upgrades help maintain compatibility with supported versions of Node.js, database drivers, and third-party APIs.
Pre-Upgrade Preparation
Before upgrading Strapi, it's important to make sure your environment and project are ready. A smooth upgrade begins with proper preparation.
1. Check the Current Version
You can confirm your installed version using:
npm list strapi
Or if using Yarn:
yarn list --pattern strapi
2. Review the Official Strapi Upgrade Guide
Strapi's documentation provides version-specific upgrade notes. Different versions---such as v3 to v4 or v4 minor updates---have varying migration requirements. Always review the breaking changes and migration notes.
3. Backup Everything
Before proceeding with any upgrade:
- Backup your entire project folder.
- Backup your database.
- Backup your environment variables.
This helps mitigate any unexpected issues during the upgrade.
4. Verify Node.js Compatibility
Each Strapi version supports specific Node.js versions. To check your current Node version:
node -v
If needed, install nvm to manage multiple Node.js versions.
Steps to Upgrade Strapi Version
Below is the detailed, step-by-step process to upgrade Strapi, especially from one v4.x version to a newer v4.x release.
1. Update Dependencies
The core Strapi packages include:
@strapi/strapi@strapi/admin@strapi/plugin-users-permissions- Additional plugins based on your project
To update all Strapi-related packages using npm:
npm install @strapi/strapi@latest @strapi/admin@latest
To update plugins:
npm install @strapi/plugin-users-permissions@latest
If using Yarn:
yarn add @strapi/strapi@latest @strapi/admin@latest
2. Apply Required Code Modifications
Major versions such as Strapi v3 → v4 require migration steps like:
- File structure changes
- Updated project bootstrapping logic
- Admin panel rebuild modifications
- API routes & controllers updates
For minor version upgrades, these changes are usually minimal.
3. Rebuild the Admin Panel
Once dependencies are updated, rebuild the admin panel to register new components and UI updates:
Using npm:
npm run build
Using Yarn:
yarn build
4. Run Database Migrations (If Needed)
Some updates require database structure updates. These often happen automatically, but review migration notes to verify if any manual updates are needed.
5. Start the Strapi Server
After the upgrade is complete:
npm run develop
Or:
yarn develop
Monitor the terminal for warnings or errors. Fix any migration-related issues immediately.
Special Considerations When Upgrading Major Versions
1. Strapi v3 to v4 Migration
This is the most complex upgrade and involves:
- Complete change in backend folder structure
- Updated routing system
- Brand-new plugin architecture
- Admin panel rebuild requirements
- Content-type builder improvements
- Different service & controller logic
Migration often requires creating a new Strapi v4 project and manually migrating content-types, controllers, and custom logic.
2. Plugin Compatibility
Always verify plugin support before upgrading. Custom plugins may require refactoring.
3. Database Schema Changes
Some models may require updates to match new Strapi requirements.
4. API Response Format Changes
A major update might introduce differences in API structure, including:
- Pagination formats
- Filters and query syntax
- Relations behavior
Testing After Upgrade
Testing is an essential step to ensure that everything works as expected after the upgrade.
1. API Endpoints
Test all endpoints manually with:
- Postman
- Thunder Client
- cURL
- Swagger/OpenAPI (if configured)
2. Admin Panel
Check:
- Content Manager access
- Media Library loading
- Plugin functionality
- Role-based permissions
3. Frontend Integration
If using React, Next.js, Vue, or Angular, test all connected features such as:
- Authentication
- Protected routes
- API calls
- Webhooks
4. Database Integrity
Verify that:
- Content-types load correctly
- Relations are intact
- No missing or corrupted data exists
Troubleshooting Common Upgrade Problems
1. Admin Panel Build Fails
Typical reasons:
- Outdated Node.js version
- Conflicting plugin versions
- Missing migration steps
2. Server Crashes on Startup
Check the logs for errors related to:
- Plugins not matching the current Strapi version
- Incorrect environment variables
- Custom code incompatible with new APIs
3. Content-Type Errors
You may need to remove .cache and build folders:
rm -rf .cache build
Then rebuild again.
4. Plugin Compatibility Issues
Disable or temporarily remove outdated plugins until updated versions are released.
Best Practices for Strapi Upgrades
1. Perform Upgrades in a Development Environment
Never upgrade directly in production. Always use local or staging environments first.
2. Use Version Control
Ensure your project is backed by Git. Commits help revert changes quickly if needed.
3. Follow Semantic Versioning
Strapi uses semantic versioning:
- Patch updates: safe to upgrade
- Minor updates: generally safe but check notes
- Major updates: require migration planning
4. Document Every Change
This helps teams stay aligned and reduces confusion during future upgrades.
5. Schedule Regular Maintenance
Regularly check for available Strapi updates using:
npm outdated
