- Drupal 9 requires PHP 8.1 or higher, so you will need to make sure your hosting environment meets this requirement. Drupal & required php 5x.
- Drupal 9 has removed several deprecated APIs and features, so any custom code or contributed modules that rely on these will need to be updated.
- Drupal 9 also introduces new features and improvements, so you should plan to take advantage of these in your upgraded site.
- It is important to test the migration process and the upgraded site thoroughly to ensure that everything works as expected.
- Consider hiring a Drupal expert to help with the migration process, as it can be a complex process and requires a good understanding of the underlying technologies.
- Make a plan to backup your site, database and files before proceeding with the migration process.
- Make sure your site's theme and modules are compatible with Drupal 9 by checking the module's page on drupal.org or by checking with the module maintainer.
- If you have custom Drupal 7 modules or Drupal 7 theme, you need to update them to be compatible with Drupal 9, or rewrite them if they are not compatible.
- It is also recommended to use a migration tool to automate the process and minimize the risk of data loss or errors.
