A POC for contentful migration

Contentful Migration Proof-of-Concept (POC)

This repository provides a practical demonstration of Contentful migrations.

---

🚀 Getting Started

The following initial steps establish the structure for managing your migrations:

1. Create a migrations directory: Establish a directory at your project's root level, where all JavaScript or TypeScript migration scripts will be stored.

2. Order Migration Files: Ensure migration files are organized in an incremental order to maintain version tracking.

3. Develop Migration Running Script: Implement a script to run the migrations.

4. Incorporate GitHub Actions: Utilize GitHub Actions for continuous integration to automate the migration process.

⚙️ Detailed Migration Workflow

The migration process follows these detailed steps:

1. Create a Migration Branch: Each new migration should be isolated in a separate branch.

2. Implement Migration Runner Script: Develop a script responsible for executing the migrations.

3. Add Migration File: Include your specific migration instructions in a migration file.

4. Export 'master' Environment Data: Preserve the latest 'master' environment content type data from Contentful by exporting and saving it.

5. Create Temporary Contentful Environment: Generate a new Contentful environment as a temporary host during the migration.

6. Import 'master' Environment Data: Load the exported 'master' environment data into the new temporary environment.

7. Run Migrations in Temporary Environment: Execute the migration scripts in the temporary environment.

8. Test the Temporary Environment: Verify the success of migrations and overall system functionality.

9. Merge Migration Branch: Once testing confirms the system's proper behavior, merge the migration branch into the master branch.

10. Execute Migrations on 'master' Branch: Run migrations on the 'master' branch post-merge.

11. Remove Temporary Environment: After successful migration, eliminate the temporary Contentful environment.

12. Manage Version Tracking: The migration script should handle version tracking. To preserve version tracking data, introduce a new Content-type on the Contentful space.

🔎 Libraries Tested

During this proof-of-concept, we evaluated two libraries: contentful-migrate and contentful-migration. Although contentful-migrate required less preliminary work, it has lingering unresolved issues. Consequently, we decided on contentful-migration for the final implementation.

Note: The preservation of the latest Content Type data from the master environment is crucial due to the lack of rollback support in Contentful.
