We know that Drupal 7 reaching the end of life on January 5, 2023. It means it will no longer receive security updates or support from the Drupal community. So organizations or individuals that use Drupal 7 should upgrade to the latest version of Drupal 10.
In Drupal migrations content, data, and configurations are transferred from one Drupal site to another. Migrations are commonly used when we upgrade from Older versions of Drupal to newer versions of Drupal.
Here’s a concise list of steps to take before starting a migration
First, back up the database of the Drupal 7 site. This ensures that if any issues are encountered during the migration, you can restore the site and re-run the process.
Using below command
Export: mysqldump -u root -p database name > filename.sql
Review the configurations and modules of the Drupal 7 site and create a list of modules and themes available in Drupal 10.
Here’s a detailed outline of the migration steps:
Create a new Drupal 10 site using Composer.
Using below command
composer create-project drupal/recommended-project my_site_name
Replace my_site_name with the desired name of your new Drupal 10 site.
Migrate Plus provides additional features and extensions for the Drupal migration framework, such as source plugins and process plugins.
Migrate Tools offers Drush commands and a user interface for managing migrations, running migrations, and viewing migration status.
The core Migrate module provides the base migration framework and APIs for migrating content and configuration from external sources to Drupal.
Migrate Drupal offers migration support for importing content and configuration from previous versions of Drupal (e.g., Drupal 6, 7) into Drupal 10.
Migrate Drupal UI provides a user interface for configuring and running Drupal-to-Drupal migrations using the Migrate Drupal module

Here’s a list of additional steps for migration
After setting up your Drupal 10 site, install the above-listed modules mentioned in the 2-step using Composer or by downloading and enabling them via the Drupal admin interface.
Install Drush if not already installed, and ensure that you have the Drush Migrate module installed. Drush provides command-line tools for managing Drupal sites, including running migrations.
If your Drupal site is multilingual, enable the necessary translation modules from the Extend page, such as Language, Content Translation, and Configuration Translation. Configure these modules as needed for your site’s language requirements.
Open your Drupal 10 site’s settings.php file
Add the Drupal 7 database connection details with the migrate key. The structure should resemble the following:

Run the following Drush command to generate migrations:
drush migrate:upgrade –legacy-db-key migrate –legacy-root=/var/www/yourdrupal10site –configure-only command on drupal.
upgrade –legacy-db-key=migrate –legacy-root=https://yourdrupal10site –configure-only.

After running the migrate: upgrade command, check the migration status using drush migrate: status

Decide whether to migrate all content at once or individual migrations based on site complexity
For complex sites with many customizations, consider choosing individual migrations.
To migrate all content, use:
Migrate all command: drush migrate: import –all
For individual migrations, use:
Individual migration command: drush migrate: import <migration name>
Run the command drush migrate: status
drush migrate rollback –all
Here are the steps for migration execution:
check your migration status using the migration status command.
Be prepared to handle errors that occur during the migration process.
Take the help of the Drupal community and Drupal documentation to handle these issues.
After completing your migrations, thoroughly check the functionality of all site pages. Ensure all links are working and images are displaying correctly on both the site and admin pages. Also, run update.php.
Sometimes you need to write code for custom modules and themes that you need in Drupal 9 from Drupal 7. So you need to upgrade your code manually.
In conclusion, drupal 7 to 10 migration is a process that requires careful planning, execution, and testing. By following the steps explained in the guide above you can successfully migrate your site from drupal 7 to its latest version.
