- Allow the site capabilities to migrate along with the content automatically.

Best Strategies for Drupal 9 Migration
1. Ensure the Preparation Is Thorough:
Undertaking the migration process to Drupal 9 does involve a great deal of preparation with some preliminary steps. Update the Drupal 7 core to the latest version combined with its extensions. Have a backup handy of the present site before the migration process. The fresh installation for Drupal 9 should have migrated modules enabled and should be in a stable form.
2. Identify Content Structure and Modules:
Identify the structure and content types and the modules that need to be migrated with possible site configurations. Use the Migrate UI Drupal module and choose the /upgrade path to automatically list the modules that cannot be migrated to Drupal 9. Install and enable Drupal 9 modules since they are not the same as in the previous version. The migration scripts should be built based on the data and content catalogue, then map the content types to the new platform version.
3. Use of the Drush Method for Drupal 9:
Utilise the method to act on commands for data migration with prompt status message delivery. Define the database connection details to connect the local development database and thus import data from Drupal 7. Use a manifest file and set up a migration set with the help of Migrate Manifest module. List them in random order but execute them based on perceived dependencies.
4. Upgrading the Site to Drupal 9:
After ensuring that the core site is upgraded to Drupal 9, enable the contributed modules and themes to Drupal 9, and finally execute the migration scripts for your custom modules.
5. Skillset Is Critical to the Migration Process:
The migration exercise is hugely dependent on the skillset of your team of Drupal developers. They should be well versed with the newer versions of Drupal and its attributes. The migration will be smooth if they are capable of using the platform embedded with significant improvements. The team of Drupal developers needs to upgrade and update themselves with later versions of Drupal for performing a speedy process that could ensure a lower budget for the migration. Use a Drupal development agency as a partner who could understand your business workflows and have enough prior experience for the migration.
6. Consider Your Resources:
Set out a budget for the migration process. A detour through the Drupal 9 migration route could be pricey, but you could also opt for phased upgrades. Consider the factors like business goals and objectives and assess the design whether the site promises a great user experience or not.
