After migrating your Drupal site to a new version (such as from Drupal 9 to Drupal 10), it's essential to thoroughly check the post-migration state and optimize the site's performance. Here are some steps and best practices to consider for checking and optimizing your Drupal site after migration:
1. Functional Testing:
- Test all the site's functionalities thoroughly. This includes forms, user registrations, logins, search functionality, and any custom features.
- Ensure that all content types, views, and blocks are displayed correctly.
- Test user permissions to make sure they work as intended.
2. Content Review:
- Check all migrated content to ensure it displays correctly.
- Verify images, videos, and other media files to ensure they are displayed properly.
- Check for any missing or broken links in the content.
3. Performance Testing:
- Use performance testing tools to assess the site's speed and responsiveness. Tools like Google PageSpeed Insights, GTmetrix, or Pingdom can provide insights into your site's performance.
- Optimize images and other media files to reduce page load times.
- Enable Drupal caching mechanisms to speed up content delivery. Configure caching settings in Drupal's performance configuration.
- Consider using a Content Delivery Network (CDN) to distribute your site's static assets across multiple servers worldwide, improving loading times for users in different locations.
4. Database Optimization:
- Optimize your database tables to improve query performance. Drupal's contributed modules like the "Advanced DB Cleaner" can help in cleaning up unnecessary data.
- Regularly monitor and optimize database indexes to enhance search and data retrieval efficiency.
5. Code Review and Optimization:
- Review custom code, especially contributed modules and themes, to ensure they are optimized for the new Drupal version.
- Identify and remove any deprecated or unused code.
- Consider using Drupal's coding standards and best practices to improve code efficiency.
6. Security Review:
- Verify that all security modules and configurations are up-to-date.
- Perform a security audit to identify and fix potential vulnerabilities.
7. SEO and Accessibility:
- Check SEO settings, including meta tags, URL structure, and XML sitemap generation.
- Ensure your site is accessible and complies with accessibility standards. Use tools like WAVE or Axe for accessibility testing.
8. Backup and Disaster Recovery:
- Regularly backup your site and database. Ensure that the backup and disaster recovery mechanisms are functioning correctly.
- Test the backup restoration process to make sure you can recover your site if something goes wrong in the future.
9. Monitoring and Performance Tuning:
- Implement website performance monitoring tools to track the site's performance over time.
- Use server monitoring tools to monitor server resources (CPU, memory, disk usage) to identify and address potential bottlenecks.
10. Documentation:
- Document all changes made during the optimization process. This documentation will be valuable for future reference and troubleshooting.
11. User Feedback:
- Gather feedback from users after the migration. Address any issues or concerns they may have.
