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
