- Make sure your Drupal 9 site is fully updated to the latest version.
- Backup Your Drupal 9 Site:
- Create a complete backup of your Drupal 9 site, including files and the database, to ensure you can revert to the original state if needed.
- Update Contributed Modules and Themes:
- Check if the contributed modules and themes you're using have Drupal 10 versions available. If not, consider alternatives or wait until compatible versions are released.
