In this blog post, we’ll explore everything you need to know to make your upgrade from Sitecore 8 to Sitecore 9 as smooth as possible. From understanding the key changes in Sitecore 9 to outlining best practices and common pitfalls, this guide will help ensure that you successfully navigate the upgrade process.
Why Upgrade to Sitecore 9?
Before diving into the technical aspects of the upgrade, it’s essential to understand why upgrading to Sitecore 9 is a worthwhile investment.
- Improved Performance: Sitecore 9 brings performance enhancements, such as better caching and faster content delivery, to provide a more responsive experience for both content editors and website visitors.
- Enhanced Scalability: Sitecore 9’s architecture is designed for greater scalability, allowing it to handle larger amounts of content and higher web traffic volumes with greater ease.
- Better Personalization: The introduction of xDB (Experience Database) in Sitecore 9 improves user experience personalization. With better tracking and analysis of user interactions, marketers can create more relevant and personalized content for their audiences.
- Integration Capabilities: Sitecore 9 offers new and improved integration tools, such as Sitecore Experience Edge, which simplifies the process of connecting to third-party systems like CRMs, ERP systems, and marketing automation platforms.
- Content Management Upgrades: Sitecore 9 comes with enhancements to the content management interface, making it more user-friendly and intuitive, which can significantly improve the productivity of content authors and editors.
Key Changes in Sitecore 9
To successfully upgrade from Sitecore 8 to Sitecore 9, it’s crucial to understand the key changes introduced in the newer version. Here are some of the most important updates: - xDB and Experience Platform:
o Sitecore 9 fully integrates xDB, which stores detailed user interaction data. While Sitecore 8 had xDB, Sitecore 9 refines the capabilities, enabling organizations to make more data-driven decisions for better content delivery and personalization.
o The Experience Platform combines the experience management capabilities with data tracking and analytics. This means upgrading to Sitecore 9 will require migration of xDB data, which might be complex depending on how much data you have. - Content Serialization (Helix and Sitecore CLI):
o Sitecore 9 promotes Helix—a set of best practices for Sitecore development that encourages modular development, clean architecture, and reusability. The Sitecore CLI (Command Line Interface) also becomes more important in Sitecore 9, allowing for easier deployment, version control, and CI/CD pipeline integration.
o If you’ve been using Sitecore 8’s previous version of serialization (like Sitecore Rocks), you’ll need to migrate to Sitecore 9’s improved serialization methodology and adopt Helix. - Sitecore Rocks and the Content Editor:
o The Content Editor in Sitecore 9 has undergone changes to improve user-friendliness, including faster load times and a more intuitive interface.
o Sitecore Rocks, the development tool, also has been enhanced, and some custom tools and integrations may need to be reconfigured for compatibility with Sitecore 9. - Sharding and Distributed Content Delivery:
o Sitecore 9 introduces a new sharded database architecture to handle large-scale websites more effectively. You may need to adjust your infrastructure to support this new distributed model, which could involve configuring your environment to ensure high availability and failover capabilities. - Experience Editor and Sitecore JSS:
o Sitecore 9 introduces JSS (JavaScript Services), which allows for a more flexible and modern approach to web development by leveraging front-end frameworks like React, Angular, or Vue.js.
o The Experience Editor has also been revamped, providing a better and more intuitive editing experience. - Security Enhancements:
o Sitecore 9 comes with several new security features and fixes, addressing vulnerabilities found in earlier versions. As security is a crucial aspect of any upgrade, be sure to review the security updates and patches before moving forward.
Steps to Upgrade from Sitecore 8 to Sitecore 9
The process of upgrading from Sitecore 8 to Sitecore 9 requires careful planning and testing to avoid disruption. Here’s an overview of the key steps to consider: - Preparation and Planning
• Audit Your Current Sitecore Implementation: Begin by assessing your current Sitecore 8 environment. Take inventory of customizations, third-party modules, and integrations to understand how they may be affected by the upgrade. This includes identifying any deprecated features or APIs.
• Review Sitecore 9 Requirements: Sitecore 9 may have different hardware and software requirements compared to Sitecore 8, such as updated versions of SQL Server, Windows Server, and .NET Framework. Ensure your environment meets the prerequisites before proceeding.
• Backup Your System: Before making any changes, ensure you have a full backup of your Sitecore 8 instance, including databases, files, and configurations. This will allow you to revert to the previous version if necessary. - Migrate xDB Data and Content
• Migrate Data: Sitecore 9 features a more robust xDB and Experience Platform, so migrating your xDB data (such as analytics and user interaction data) from Sitecore 8 to Sitecore 9 is essential. This is often one of the most complex tasks in the upgrade process, especially if you have a large amount of data.
• Use Sitecore’s Upgrade Tools: Sitecore provides tools to help migrate content and configurations. The Sitecore Upgrade Guide offers detailed instructions on how to perform this task. Tools like Sitecore Content Serialization and the Sitecore Data Migration Toolkit can assist in the migration. - Update Custom Code and Integrations
• Refactor Custom Code: Sitecore 9 introduces changes to the APIs, so you’ll likely need to refactor your custom code to ensure compatibility. This may include updates to your pipelines, processors, and Sitecore modules.
• Third-Party Integrations: Review and update integrations with third-party tools such as CRMs, marketing automation platforms, or payment gateways. Ensure that your integrations are compatible with the new version of Sitecore. - Testing
• Set Up a Staging Environment: Perform the upgrade in a staging environment first. This allows you to test everything in a controlled setting before making changes to the live site. Ensure all components—such as the site’s front-end, back-end, and integrations—work seamlessly.
• User Acceptance Testing (UAT): Involve your content authors, marketers, and other key stakeholders in UAT to verify that the site functions as expected in Sitecore 9. Pay particular attention to the Experience Editor and personalization features. - Deployment and Go Live
• Deployment: Once testing is complete and you’re confident that everything is working, plan the deployment. Sitecore 9 supports more modern deployment strategies, such as using Sitecore’s Continuous Integration/Continuous Delivery (CI/CD) pipelines. Ensure you have a solid plan in place for the go-live phase.
• Monitor Post-Upgrade: After upgrading, monitor the system for any issues, particularly performance-related ones. If any problems arise, have a plan for quickly resolving them.
Common Pitfalls and How to Avoid Them - Neglecting to Test Custom Code: Custom code can break during an upgrade, especially when using new APIs in Sitecore 9. Ensure you perform thorough testing before going live.
- Underestimating the Complexity of xDB Migration: Migrating xDB data can be time-consuming, especially for large websites. Allocate adequate time and resources for this step.
- Failure to Address Infrastructure Changes: Sitecore 9 may require changes to your infrastructure to support new features such as sharding. Don’t skip infrastructure preparation to ensure a smooth upgrade.
- Skipping User Training: Sitecore 9 introduces significant changes to the UI and workflows. Provide proper training for content editors, marketers, and other users to ensure they’re comfortable with the new interface.
