How to Perform Sitecore to Drupal Migration?

Migrating from Sitecore to Drupal involves multiple steps, from pre-migration planning to the actual data migration and post-migration. Below is a detailed guide to performing Sitecore to Drupal migration:

1. Set Up Your Drupal Environment

Set up a new Drupal instance that will serve as the destination for your migrated content. This includes installing Drupal and necessary modules and configuring the environment to support the migration.

Step 1: Install Drupal using Composer. Here is the command to do so:

composer create-project drupal/recommended-project my_site_name_dir
cd my_site_name_dir

Step 2: Install the necessary modules required and enable them for the migration. Install To download migration-related modules, run the command:

composer require drupal/migrate_plus drupal/migrate_tools

Step 3: Once done, enable the modules you downloaded:

drush en migrate_plus migrate_tools migrate_drupal -y

Now you will have a fully prepared Drupal environment, ready to receive content from Sitecore.

2. Prepare Data for Migration

Export your content from Sitecore and transform it into a format compatible with Drupal. This involves writing scripts or using tools to convert data into structured formats like CSV or JSON.

To perform data transformation into a format compatible with Drupal’s structure you can use python scripts. Here is how you can convert JSON data to CSV:

import json
import csv
with open('sitecore_data.json') as json_file:
    data = json.load(json_file)
with open('drupal_data.csv', mode='w') as csv_file:
    writer = csv.writer(csv_file)
    writer.writerow(['Title', 'Body', 'Image', 'Tags'])  # Example fields
    for item in data:
        writer.writerow([item['title'], item['body'], item['image'], item['tags']])

This step results in a cleaned and structured data set that can be imported into Drupal. It will ensure that all content is ready for migration.

3. Create Migration Scripts

Develop migration scripts that will automate the transfer of content, media, and custom fields from Sitecore to Drupal. These scripts ensure the data is correctly mapped and imported.

Step 1: Create a migration YAML file for content types:

id: migrate_sitecore_articles
label: 'Migrate Sitecore Articles'
source:
  plugin: csv
  path: modules/custom/sitecore_migration/data/articles.csv
  ids:
    - id
  fields:
    - name: title
      label: 'Title'
    - name: body
      label: 'Body'
    - name: image
      label: 'Image'
    - name: tags
      label: 'Tags'
process:
  title: title
  body/value: body
  body/format:
    plugin: default_value
    default_value: full_html
  field_image:
    plugin: file_import
    source: image
    destination: 'public://images/'
  field_tags:
    plugin: migration_lookup
    source: tags
    migration: sitecore_tags
destination:
  plugin: 'entity:node'
  default_bundle: article

Step 2: Migration of media can be handled by mapping the file paths:

process:
  field_image:
    plugin: file_import
    source: image
    destination: 'public://images/'

Step 3: Handle custom fields by writing specific process plugins or using existing ones:

process:
  field_custom_field:
    plugin: custom_plugin
    source: custom_data

By the end of this step, you will have a set of migration scripts that are ready to run and capable of moving your data accurately from Sitecore to Drupal.

4. Theme Development

Develop a custom Drupal theme or adapt an existing one to match the look and feel of the Sitecore site. Drupal’s Twig templating engine will be crucial here:

{# Example: A basic page template in a custom theme #}
<div class="page">
  <header>
    <h1>{{ page.title }}</h1>
  </header>
  <div class="content">
    {{ content.body }}
  </div>
</div>

This custom theme development in Drupal will ensure that the design of your new site remains the same as that of Sitecore.

5. Run Test the Migration

Before performing the full migration, it’s crucial to test the process with a subset of data. This helps identify any issues in the migration scripts or data mapping.

Step 1: Execute the migration using the drush command. Here is how:

drush migrate:import migrate_sitecore_articles

Step 2: Once done, check the results and ensure that data is correctly mapped. You may also verify the content in the Drupal backend to ensure data integrity and perform automated tests to validate the migrated data.

After testing, you will have validated migration scripts and identified any necessary adjustments. That will reduce the risk of errors during the full migration.

6. Full Migration Execution

With your scripts tested, you can now execute the full migration, transferring all content and media from Sitecore to Drupal.

Step 1: Execute the full migration for all content types, media, and custom fields:

drush migrate:import --all

Step 2: Review the migrated data to ensure everything has been correctly imported. Fix any issues or errors found during the validation.

This step culminates in the complete migration of your Sitecore content to Drupal, with all data imported and ready for final adjustments.

7. Post-Migration Tasks

Once the migration is complete, there are additional tasks to ensure your Drupal site is fully functional. This includes setting up URL redirects, customizing layout, and optimizing performance.

Step 1: Use the Redirect module to set up URL redirects from old Sitecore URLs to new Drupal URLs:

drush en redirect -y

Step 2: Use Drupal’s tools, like Layout Builder, Views, and Blocks, to further optimize the content presentation of your site.

Step 3: Optimize Drupal’s performance by enabling caching, optimizing images, and configuring content delivery networks (CDNs).

By the end of this step, your Drupal site should be fully operational, with redirects in place, the theme configured, and performance optimized.

8. Launch

With the migration and post-migration tasks completed, your new Drupal site is ready to go live. This step involves deploying the site and monitoring its performance.

Step 1: Deploy the new Drupal site to a live server and monitor the site for any issues during the launch phase.

Step 2: Set up ongoing monitoring to track site performance, user behavior, and Drupal SEO metrics. Plus, regularly update the Drupal core and modules to keep the site secure.

After this step, your Drupal site is live, replacing the old Sitecore site, and is being monitored to ensure a smooth transition.

Migrating from Sitecore to Drupal is a complex task that involves detailed planning, data transformation, and thorough testing. By following the above process with necessary changes, you will be able perform Sitecore to Drupal migration. But if you face any error or want us to migrate your site, consider hiring Drupal developers.
