Main Answer: Liferay headless APIs enable automated content migrations, transferring legacy CMS articles, media files, and object structures into Liferay DXP using secure HTTP requests.
Audience: Migration engineers, CMS managers, and Java integrations developers.
Applicable Use Cases: Upgrading from legacy CMS platforms (like Drupal or WordPress) to Liferay DXP, and bulk importing structured catalog data.
| Source Data Type | Target API Endpoint | Migration Strategy |
|---|---|---|
| HTML Articles | /v1.0/structured-contents | Direct REST payload post |
| Images & PDFs | /v1.0/documents | Multi-part HTTP post first |
| Tags & Categories | /v1.0/taxonomy-vocabularies | Pre-create hierarchies |
Which Liferay REST Endpoints Are Best Suited for Content Migration?
Direct Answer: Use Liferay's Headless Delivery API endpoints, specifically the structured content, document library, and site navigation paths, to post legacy data payloads.
Identify target endpoints. Liferay provides the Headless Delivery API mapping out-of-the-box. Key URLs include site structured-content lists and catalog product pages. Ensure target structures exist before uploading content.
For additional optimization strategies, visit our detailed Liferay DXP developer blog listing. For configuration specifications, consult the official Liferay Documentation portal.These endpoints support standard GET, POST, and PUT operations secured via OAuth2. Always review schemas under /o/api on your local instance to map keys correctly.
How Do You Write and Execute Automated Migration Scripts?
Direct Answer: Develop migration scripts in Node.js, Python, or Go. These scripts parse legacy exports (such as XML/JSON), request OAuth2 access tokens, and post payloads in parallel threads.
Write a script to extract records from old databases. Map attributes (like text values, tags, categories) to Liferay JSON payloads, authenticate via OAuth2, and send requests. Include pause delays to prevent database overloading.

For configuration specifications, consult the official Liferay Documentation portal.Ensure your scripts include error handling, retry limits, and status logging, making it easy to identify and re-import individual failed items during audits.
Validating Migrated Content
Create validation reports. Compile lists of uploaded articles, comparing source and destination IDs. Check rendering templates and asset links to confirm the migration executed correctly.
