Blog 2: Preparing for Migration from JSS to Sitecore Content SDK

Hi Sitecorian Folks! 👋

Welcome back! In the last blog, we introduced the Sitecore Content SDK and discussed why it’s a better solution for headless content management compared to JSS. Now, it’s time to roll up our sleeves and talk about what needs to be done before you actually start migrating your projects.

Migrating from Sitecore JSS to the Content SDK may seem daunting at first, but with a clear plan in place, it can be a smooth transition. In this blog, we’ll walk through the key steps you should take to prepare for the migration.

1. Assess Your Current JSS Project

Before migrating, the first step is to assess your current setup and identify any potential issues that might arise during the transition. This will help you create a migration strategy and avoid surprises down the road.

Key things to assess:

• API Integrations: Review how you’re fetching data in your JSS application. Are you using GraphQL, REST APIs, or Sitecore Web API? The Content SDK uses its own set of APIs, so you’ll need to identify where changes are needed.
• Front-end Framework: Check which front-end framework (React, Angular, Vue, etc.) your app is using. The Sitecore Content SDK has built-in support for modern frameworks like Next.js and React, but you’ll need to adjust your setup accordingly.
• Sitecore Item Models: Take a look at the way your Sitecore items are structured. The Content SDK uses a more streamlined and developer-friendly model for content delivery, so you may need to adjust your content structure for optimal performance.
• Media Management: If your app uses media items, make sure you’re ready to switch over to the new content delivery mechanisms.

2. Understand the Core Differences in Architecture

The architecture of Sitecore Content SDK is more streamlined than JSS, and understanding the differences will make your migration smoother. Here’s what you need to know:

• Content Delivery: The Content SDK relies on headless delivery via RESTful APIs rather than embedding content directly in the app, which was often done in JSS via API calls to Sitecore.

Action Item: If you were using custom data-fetching logic in JSS, you’ll need to replace this with the Content SDK’s simplified API structure.

• Authentication and Authorization: JSS apps often relied on Sitecore’s Forms Authentication or custom OAuth configurations. The Content SDK uses OAuth to authenticate API calls in a more modern and secure way.

Action Item: Ensure your authentication system is compatible with OAuth-based access tokens used in the Content SDK.

• Deployment: JSS apps often had separate deployments for the back-end and front-end. With the Content SDK, the deployment process is more unified, as Sitecore XM Cloud is used for both content management and content delivery.

Action Item: Review your current deployment setup and plan how you’ll integrate the front-end and back-end deployments under the new Sitecore architecture.

3. Plan the Migration Timeline

Moving from JSS to the Content SDK doesn’t need to be an overnight project. In fact, it’s a good idea to break down the migration into manageable phases.

Here’s how you can approach it:

• Phase 1: Setup and Testing: Set up a clean environment for your Content SDK app. This can be done in parallel with your existing JSS setup to minimize downtime.
• Install the necessary dependencies for the Content SDK and choose the front-end framework (Next.js, React, etc.).
• Create a small test project to familiarize yourself with the new structure and API calls.
• Phase 2: Migrate Core Components: Begin migrating critical features and components over to the Content SDK. You can start with less complex elements (e.g., page layouts, media items, or simple Sitecore items).
• Action Item: Focus on the main components that are essential for the content delivery in your app.
• Phase 3: Full Migration: Once the core components are migrated, start moving over the remaining parts of the app. This is when you’ll want to fully switch over to the Content SDK and test every part of the application.
• Phase 4: QA and Optimization: After the migration, run through rigorous QA testing to ensure everything works as expected. Optimize your content fetching, API calls, and front-end rendering for performance.

4. Identify and Mitigate Potential Migration Issues

As with any migration, there will be challenges along the way. Here are some common issues developers face when migrating from JSS to the Content SDK — and how to handle them:

• Incompatible API Calls: The Content SDK introduces new API structures that are different from JSS. If your app relies heavily on JSS-specific API calls (like graphql), you’ll need to refactor your code to work with the SDK’s APIs.

Solution: Identify all places where you’re calling APIs directly in your code and plan to replace them with the SDK’s native methods.

• Content Model Mismatches: Sitecore’s content models may need to be updated to take full advantage of the Content SDK’s enhanced features.

Solution: Review your Sitecore templates, fields, and content models to ensure they’re compatible with the Content SDK’s streamlined architecture. Consider redesigning models for better performance.

• Authentication Changes: If you’re using custom authentication mechanisms with JSS, you’ll need to ensure they’re compatible with the Content SDK’s OAuth-based system.

Solution: Check your authentication settings and switch to the Content SDK’s OAuth-based authentication if needed.

• Performance Bottlenecks: Even though the Content SDK offers improved performance, you may encounter issues if your code isn’t optimized.

Solution: After migration, take the time to profile your application’s performance. Look for redundant API calls or inefficient data-fetching strategies and optimize them.

5. Documentation and Resources to Help You Along the Way

Before diving into the actual migration, here are some helpful resources:

• Sitecore Content SDK Documentation: Always the best place to start for official guidelines and best practices.
• Migration Guides: Look for migration-specific documentation from Sitecore to ensure you’re following the right steps.
• Developer Forums: Sitecore’s community forums, Stack Overflow, and GitHub repositories can be invaluable for troubleshooting common issues.

Conclusion

With the right preparation, migrating from JSS to the Sitecore Content SDK doesn’t have to be a major challenge. By carefully assessing your current setup, understanding the architectural differences, and planning your migration in phases, you can make the transition smoother and more efficient.
